TheVOIPGirl.com’s had another nice welcome from PhoneBoy (no, we’re not related), a prolific VOIP, telecom and technology blogger with an affable writing style. He explains things…

Check out his review of GotVoice and you’ll see what I mean. GotVoice is an interesting service that takes voicemail messages from different voicemail services (including VOIP ones) and sends them to your email inbox. You get convenient access to all your voice messages in one place. He also points out a few shortcomings of TheVoipGirl.com that I hasten to address. Thanks PhoneBoy!

Today BridgePort Networks announced the commercial availability of MobileSTICK, a USB device that transforms your PC or laptop into an extension of your cell phone. When you plug MobileSTICK into a PC or laptop with a fixed line or Wi-Fi broadband connection, the device launches a PC softphone, secured by a SIM card that utilizes the your existing mobile phone number to make and receive phone calls, SMS messages and multimedia (MMS) messages. Your existing mobile remains active and continues to utilize its existing SIM.

Ken Camp had the opportunity a few months ago to do a podcast with BridgPort’s Sanjay Jhawar that explains the MobileSTICK technology in detail. It’s really good and worth a listen.

The good news is that hovering your mouse over just about anything in the Skype window will display a tool tip (a little one-sentence definition or status report).

However, I found that almost right away I needed a cheat sheet for the online status icons, those green or gray clouds beside each contact. If you have anything to add or change, please do.

 Online: the person can receive calls or chats. If you set your status to , you can receive calls/chats from other Skypers. Depending on your privacy settings, you can receive calls from anyone, from people in your contact list, or from people who you’ve authorized to see your online details. To set privacy settings, go to Tools ->Options->Privacy.

 SkypeMe: the person is in SkypeMe mode, which means that everyone on Skype knows he/she is available and interested in talking or chatting, including contacts they don’t know. If you set your status to SkypeMe, you are allowing calls and chats with other Skypers who can find you by searching the Skype directory. To turn SkypeMe mode ON or OFF, go to File –> Change Online Status (Windows) or Account -> Change Status (Mac OS X).

 Invisible: the person appears to you as  offline, which means you can’t call or chat with them. If you set your status to invisible, you will appear as  to everyone else. Use invisible if you want to be able to make your own calls or chats, but don’t want to receive them. You’ll also be able to see the online status of everyone else in your contact list, even though you’ll appear to them to be offline.

 Away: the person temporarily can’t be reached–out to lunch, away from computer, in a meeting or whatever. If you set your status to Away, you are still notified of incoming calls or chats. Skype automatically switches your online status to Away if you have been inactive for a certain number of minutes. Go to Tools ->Options ->General to change this setting.

 Not available: the person can’t be reached. Sounds a bit more long term than Away. If you set your status to Not Available, you are still notified of incoming calls or chats. Skype automatically switches your online status to Not Available if you have been inactive for a certain number of minutes. Go to Tools ->Options ->General to change this setting.

 Do not disturb: the person doesn’t want to be bugged. Calls or messages are queued for you to check later. If you set your status to Do Not Disturb, you won’t be notified of incoming calls or chats (no pop-ups or ringtones).

 Not sharing: the person does not give you permission to see if he/she is online, offline, away, and so on. It’s probably nothing personal. When adding the contact you may have decided not to request their details, or they may have dismissed your request. To ask again if they’d like to share details, right-click the contact name and select Request Contact Details.

 Offline: the person is not available through Skype. They may have set their status to offline or invisible, or they may have logged off. If you set your status to Offline, you can’t make or receive calls/chats with other Skypers. But, if you have a voicemail account, people can leave you messages. You can also call forward your calls when offline to another number (either a regular number or Skype name), and you can still make SkypeOut calls (calls to regular numbers). 

 Skypeout contact: a person with a regular landline/mobile number. Not a Skype number.

Bloggers like Andy and Phoneboy have made mention of Gizmo Project growing pains and bugs. Sometimes timing is everything because I was just thinking that. Well, maybe I’m feeling a little cranky today. I haven’t seen the problems Andy and Phoneboy have, but I do see other Gizmo-related errors and general “not responding” messages regularly, and it’s getting me down.

I’ve also never been able to get GizmoCall to work for me at all despite numerous pleas to tech support and the forums. I reported on it’s launch but was waiting to give a user opinion. Never happened. I really think that Gizmo is going in the right direction with the additional services like SMS, web calling, integration with other IM networks. I recently decided to use Gizmo as my primary chat interface since I can integrate with MSN,Yahoo, Google, and others. A new features lets you import your MSN contact list into Gizmo at one shot instead of laboriously one by one. And Gizmo is SO easy to set up with the Nokia N95 which means I can use it to make mobile internet calls.  I also use Gizmo to handle all my incoming calls through GrandCentral. Another big plus.

When the sun is shining you can overlook application not responding and other weirdness. But you can also get tired of making excuses. Sigh. I feel it’s kind of like a great outfit, love the color, the style, looks good on me, perfect for the occasion, but it doesn’t quite fit right.

I’ve been playing catchup a little this week so I’m reading the flurry of posts that started with SightSpeed’s Peter Csathy on Video as the Next Big Thing in Social Networking. Luca Filigheddu and Ken Camp had some interesting things to say. However, PhoneBoy really put it together for me.

First, he says that until video is literally built in everywhere, like right in my laptop or as part of a web site, the masses on the whole may not bother. I see this already in my efforts to get friends and family to join SightSpeed. After all, it’s free, it works, and it’s easy. What’s the holdup? Seems that my friends are either a little suspicious of something FREE off the Internet (what’s the catch) or they simply don’t have a webcam. Why can’t they could just rush down to Staples immediately and spend $40 on a web cam and some gel pens? Not everyone’s a Staples geek like me. If the technology isn’t right there staring them in the face, it’s not a priority.

Phoneboy goes on to say that even if technology catches up and “the ability to do video is as ubiquitous as a mobile phone”, people may still not use it to interact on the Internet. It depends on what you have to say and how you want to say it. For example, I can convince my parents to use SightSpeed because they see huge value in the ability to see and talk to their kids in other cities. My friends are lukewarm on the idea of video calling me just to chat because it seems unnecessary (and they can’t do dishes or look for car keys at the same time).

That said, I’m still trying to get friends, family and colleagues into my SightSpeed network. I may have to resort to webcams as Christmas presents. Because SightSpeed has a great feature that lets you email video messages, I’m just gonna video mail them until a) they tell me to stop, or b) give in and try it.

Free Internet phone service lets you to make free long distance calls over the Internet in three different flavors. The first enables you to make calls from one phone to another as long as both are connected to broadband lines. The second allows you to make calls from one computer to another and the third makes calls possible from a computer to a traditional phone.

But, there are limitations to free services. Let’s take a look.

Phone-to-phone service providers require that you purchase their telephone adaptor (or ATA). As long as you are calling other people who have purchased the same equipment, the call is free. PhoneGnome is one such service. The PhoneGnome adaptor costs about $119. You literally plug it in to your broadband connection and to your regular phone, it configures itself, and you are good to go. You can start calling other PhoneGnome users anywhere for free. You don’t have to switch phone numbers or change telephone companies. Vonage, Packet8, AT&T CallVantage, and others you may have heard of follow the same model.

PC-to-PC service providers allow users to make free calls from one PC to another. Both parties need a PC with an Internet connection and some software easily downloaded from the Net. However, for a call to ring through, both parties have to be online at the same time and have the same, or at least compatible, software. By adding voicemail to a PC-to-PC service though, callers can leave messages even when you’re not online. Unfortunately, voicemail may or may not be free.  Skype, Gizmo Project, and FWD are three typical PC-to-PC services.

PC-to-phone services let you to call a regular phone numbers for free. However, you may be restricted to the locations that you can call or the length of the call. VoipBuster, for example, provides free calls from your PC to landline phones in about 30 countries. The restrictions are a little bit complex, but free is free…Lucky for us, the bigger software-based phone companies are trying hard to entice users so there’s also a current wave of promotions trumpeting free calls to landline phones. Skype for example offers free calls to any phone within North America until the end of the year. Gizmo offers free calls to phones in 60 countries as long as both parties maintain an active Gizmo Project account.

In all of these cases, free Internet telephone services make money by selling credits for calling minutes to landline phones or mobiles, long distance destinations, or phone numbers not on the same VOIP service. Rates are low, however, and you can expect to save significantly over traditional long distance companies. For regular phone users to call you on your free Internet phone account, you must “buy” or subscribe to a conventional phone number. Most services allow you to buy a phone number in different locations, so if your family is in the UK and wants to phone you regularly, you can buy a local UK number that they can call for free or inexpensively.

I’ve been wondering about the GrandCentral “One number for life” mantra, and TalkPlus‘ second number for your mobile phone. While I understand these products target different markets, I find it hard to keep them distinct in my mind. It dawned on me that this could be a problem that consumers have as well.

There’s a lot of chatter about Voice 2.0 applications–the user in control not the network–but that is the VOIP blogosphere talking. Me, I think okay, I get another number, it’s free for now, and it’s solving what problem exactly? 

GrandCentral:

Provides a phone number not tied to a device or location. When people call this number, the phones you have “attached” to it ring, like your cell phone, home phone, and office phone. Up to six phones can be linked to your GrandCentral number. The service is all about giving you control over how people reach you (inbound calling) as opposed to how you place calls. Callers can leave voice messages that can be checked by phone, email or online. You’re notified of a voice mail via email or text message to a cell phone. And you can flag unwanted callers as spam. It’s also free.

You need it if people have a hard time tracking you down. You find yourself playing telephone tag. You WANT to be found but heck, you’re always bouncing between work, home, and on the road.

TalkPlus:

Provides a second number for your cell phone so you can separate personal life and work life. The number can be used as a second line for business, dating, classified ads, online auctions, social groups, or a second residence. Like GrandCentral, unwanted callers can be blocked while priority numbers ring through. When making outbound calls, you can specify which caller ID to use so that the person you are calling doesn’t know how or where you’re calling from.

You need it if your mobile phone is your primary means of communication but the  separation of work and play is important to you. You want people to know that you’re calling from the office (the caller ID says this is a work-related call) even though you’re calling from home or the beach in Maui. You are also concerned about personal privacy and want to make sure that your personal number is only available to the people you want to have it.

***

In talking with Craig Walker, GrandCentral CEO, he tells me they couldn’t be more different than TalkPlus.

“Our philosophy is that we don’t need MORE numbers for people to reach us at…we need less.  As long as I have the control over my inbound calling that GrandCentral gives me, there’s no reason that I would want to juggle different personas. I don’t want phone numbers that identify me as being located at a certain place or doing a certain thing, I want a phone number that is personal to me.  If you want to reach me, call my ONE NUMBER.  I’ll be able to answer it wherever I want…I will be able to know who’s calling every time, and I’ll even be able to listen in on the voicemail as its being left if I’m still unsure whether I want to take the call.  When somebody calls me, they shouldn’t be able to “figure out” or know where I am based on the number…if I’m in the office, working from home or on the beach, that’s my business.” 

Obviously there’s more to both GrandCentral and TalkPlus than what I describe here, and the enthusiasm voiced by many in the VOIP blogging community seems to be not so much what these services are doing today, but what we can expect from them in the future.

To set up a free GrandCentral account, click here. To sign up for a TalkPlus sneak peak beta (for Cingular, T-Mobile, and Sprint customers in select U.S. states only), click here. TalkPlus won’t be a free service like GrandCentral and pricing is to be determined.

Did you know that for the year 2006, “J” was the most popular letter of the alphabet? Okay, I made that up. I have no idea if it’s true, but three out of ten most popular baby names last year started with J….

I had a comment a few days ago from Eric C. wanting to know about Jaxtr, Jangl and JaJah. What’s the difference? What indeed! People (like me) are starting to ask questions like this because…who can remember what these guys do! They sort of sound alike, they’re in the same industry space, they appeal to the same type of folks. Eric then wanted to know how the Js relate to GrandCentral. Oiy!

Jaxtr:

• Provides a click-to-call widget (button) for social networking sites like MySpace, web sites, and blogs. Visitors to your page have the option to call you, send you a text message, or leave you a voice message. They don’t need a microphone or headset. They call you by entering their phone number in the widget, Jaxtr then provides a local number for them to dial.
• Free registration, then you buy jax credits to forward calls to your phone. 100 free credits per month.  You can send unlimited calls to voice mail for free and unlimited text messages for free. Calls to other Jaxtr users are also free.
• No software download required.
• Unique feature is Voiceblast. You can record your own message or greeting that’s played automatically or on mouse-click when a someone visits your web page. I’ve added my voiceblast to my About page here.
• Like Jangl, Jaxtr has privacy options that allow you and the person calling to hide your phone numbers or email addresses.
• Like GrandCentral, you can block incoming calls or forward calls based on caller ID. Unlike GrandCentral, Jaxtr does not give you a 10-digit phone number that can be dialed from any phone. People calling you are given a special 10-digit number they can use, but they must use the same phone every time. If they call from a different phone, Jaxtr provides a different number.
• I like it.

Jangl:

• Provides a click-to-call widget (let’s call this widget dialing) for social network sites, web sites and blogs that masks the incoming and outgoing numbers. It’s a way for people to make and receive calls without giving out phone numbers. I guess the advantage here is privacy. For example, you can post the Jangl widget on MySpace without revealing your personal phone number.
• When you register, you receive a Jangl ID that people use to call you. Someone enters your Jangl ID in the online widget, Jangl then gives them a special number to call you on a regular phone. Your number and the calling person’s number are never exchanged.
• Registration is free, then you pay per call based on telephone company charges.
• You can choose from several cool looking widgets
• Not really like GrandCentral at all, except in that they both have widget dialing (GrandCentral recently introduced web buttons).
• Sounds a lot like Jaxtr but I still found Jangl a bit confusing and not a lot of info or online support. I haven’t used it much.

JaJah

• Provides web-based dialing, or dialing from a web page, without a microphone or headset. All calls are made phone to phone, whether landline or mobile. This means the person you’re calling does not have to be connected to the internet.
• You log in to your Jajah account, enter your friend’s number, and click the CALL button. Your phone will ring, you pick up, then your friend’s phone will ring.
• No software download required.
• Other Jajah services and tools include conference calls, call scheduling, access to Jajah phone book from the web browser on your mobile phone, Jajah plugins for Google, Outlook, Mac OS X Address Book, Firefox, and Plaxo
• Registration is free, you get 5 minutes free calling anywhere, then you pay as you go. Calls to Jajah users are free.
• I have an account but haven’t used it.

I’ll leave TalkPlus, Talkster, and Talk-Now for another time….”Tango of the Ts” perhaps? 

Analog audio signals: Analog audio signals are used to transmit voice data over telephone lines. This is done by varying or modulating the frequency of sound waves to accurately reflect the pitch of the sound. The same technology is used for radio wave transmissions.

ATA: ATA or the analog telephone adaptor is the hardware device that connects the conventional telephone to the Internet through a high speed bandwidth line, provides the interface to convert the analog voice signals into IP packets, delivers dial tone and manages the call setup.

Bandwidth: Bandwidth is the volume of data that can be transmitted over a communication line in a fixed amount of time. It is expressed in bits per second (bps) or bytes per second for digital devices and in cycles per second, or Hertz (Hz) for analog devices. Bandwidth can also be defined as the difference between a band of frequencies or wavelengths.

Broadband: It is a term used to define high speed Internet connection, generally provided by cable TV, DSL or dedicated telecom lines. The high speeds are achieved by the carrying capacity of the cable that can carry multiple messages simultaneously.

Cable modem: The cable modem is a device that is used to connect a computer to the high speed coaxial cable run by cable TV companies to provide access to the Internet. The connection is made through an Ethernet port, which is a shared medium and can affect download speeds if too many users log on simultaneously to the Internet on that particular cable segment. However, despite this cable modems provide extremely fast access to the net.

Circuit switched networks: These networks have been used for making phone calls since 1878. They use a dedicated point-to-point connection for each call. This reduces their utility because no network traffic can move across the switches that are being used to transmit a call.

Client (Softphone client): The software installed in the user’s computer to make calls over the Internet.

Codec: Codec is a term that arises from the Compressor-Decompressor or enCOder/DECoder process. It is used for software or hardware devices that can convert or transform a data stream. For instance, at the transmitting end codecs can encode a data stream or data signal for easy transmission, storage or encryption. At the receiving end, they can decode the signal in the appropriate form for viewing. They are most suitable for videoconferencing and streaming media solutions.

Compression: This is a term that is used to indicate the squeezing of data in a format that takes less space to store or less bandwidth to transmit. It is very useful in handling large graphics, audio and video files.

Data compression: This is the process that is used to compress large data files into mall files so that they use less bandwidth during transmission and less disk space when stored. The compression depends upon the repeatable patterns of binary 0s and 1s. The higher the number of repeatable patters, the higher is the compression. The right compression codes can compress data files to 40% of their original size. The graphics files can be compressed even more – from 20% to 90%.

DSL modem: A DSL modem is a device that is used to connect one or more computers to the high speed DSL line provided by a DSL operator to gain access to the Internet. The customers use these modems to log on the net to download or transmit data. Since the DSL lines have high bandwidth capacity the data transfer speeds are very high.

E911: E911 is the short form of the term Enhanced 911, and is used for providing emergency service on cellular and Internet voice calls.

Emergency 911 calls: This is an emergency telephone number that handles all calls related to police, fire or medical emergencies. The number, which is allotted under the North American Numbering Plan (NANP), is answered by either a telephone operator or an emergency service dispatcher, who, in turn, alerts the appropriate emergency service.

H.323: An ITU standard that lays down guidelines for real time voice and videoconferencing utilities on the Internet. The H.323 standard supports voice, video, data, application sharing and whiteboarding and defines media gateways for conversion to packets.

Internet congestion: Internet congestion occurs when a large volume of data is being routed on low bandwidth lines or across networks that have high latency and cannot handle large volumes. The result is slowing down of packet movement, packet loss and drop in service quality.

IP address: An IP address, also known as Internet Protocol address, is the machine number used to identify all devices that are connected to the net. Each device has its own unique number which it uses to communicate. This number is fixed in the case of those computing devices that have a fixed IP address. The rest are allotted a dynamic IP address, which is valid for the period they are connected to the net. The numbers range from 0.0.0.0 to 255.255.255.255.

IP mapping: IP mapping is the process of identifying IP addresses on the basis of their geographical locations. The mapping enables web administrators to pinpoint the location of any computing device connected to the Internet.

IP Phone: An IP phone is one that converts voice into digital packets and vice versa to make phone calls over Internet possible. It has built-in IP signaling protocols such as H.323 that ensure that the voice is routed to the right destination over the net. The IP phones come with several value added services like voicemail, e-mail, call number blocking etc.

IP telephony: IP telephony refers to the two-way transmission of voice over Internet. The voice is transmitted in real time by using the packet-switched technology over the IP network. Some of the applications that use IP telephony are IP-based phone services, voice over instant messaging and videoconferencing.

IP: IP, which is the acronym for Internet Protocol, defines the way data packets, also called datagrams, should be moved between the destination and the source. More technically, it can be defined as the network layer protocol in the TCP/IP communications protocol suite.

ITU: ITU, which is the acronym of International Telecommunication Union, is a telecommunications standards body based in Geneva. It works under the aegis of the United Nations and makes recommendations on standards in telecommunications, information technology, consumer electronics, broadcasting and multimedia communications.

Jitter: It is a term used to indicate a momentary fluctuation in the transmission signal. This happens in computing when a data packet arrives either ahead or behind a standard clock cycle. In telecommunication, it may result from an abrupt variation in signal characteristics, such as the interval between successive pulses.

Kbps: Kbps is the acronym for kilobits per second and is used to indicate the data transfer speed. If the modem speed, for instance, is 1 Kbps then it means that the modem can route data at the speed of one thousand bits per second.

Lag: Lag is the term used to indicate the extra time taken by a packet of data to travel from the source computer to the destination computer and back again. The lag may be caused by poor networking or by inefficient or excessive processing.

Latency: Latency is the time that elapses between the initiation of a request for data and the start of the actual data transfer. This delay may be in nanoseconds but it is still used to judge the efficiency of networks.

Mapping: The process of identifying all related data fields or data streams and putting them in an easily identifiable context. For example, IP mapping enables users to pinpoint the geographical location of any computing device on the Internet.

MGCP: Acronym of Media Gateway Control Protocol. Used for a Voice over IP system. It consists of a Call Agent and a set of gateways, of which at least one works as the “media gateway” and performs the conversions.

NANP: Stands for North American Numbering Plan. A telephone numbering system that has evolved the way area codes and numbers are allotted. The system was established in 1947 and covers the United States, Canada and a few neighboring areas. It uses a three-digit area code and seven-digit telephone numbers. Its fiat is, however, limited to the public switched telephone networks only.

Net Phone: A net phone uses the Voice over IP technology to make voice calls. These calls are made by converting analog sound signals into digital data packets, and then moving the packets to their destination over the net.

Packet loss: Packet loss is the term used to indicate the loss of data packets during transmission over a computer network. This may happen on account of high network latency or on account of overloading of switches or routers that are unable to process or route all the incoming data.

Packet switched networks: These are networks that break messages into small digital packets, stamp each packet with the destination IP address, and route them across different channels to their destination where they are reassembled in their proper sequence. This is done to avoid network congestion and speed up data movement from multiple sources.

Packet: A packet is a unit of data transmitted over the network in a packet-switched system. It consists of a header that stores the destination address, a data area which carries the information that is being transmitted, and a trailer which contains information to prevent errors during transmission.

Peer-to-Peer (P2P): The term peer-to-peer is used to indicate a form of computing where two or more than two users can share files or CPU power. They can even transmit real time data such as telephony traffic on their highly ad hoc networks. Interestingly, the peer-to-peer network does not work on the traditional client-server model but on equal peer nodes that work both as “clients” and “servers” to other nodes on the network.

POTS: POTS is the short form of plain old telephone service. It transmits voice as analog data on communication lines that are much slower when compared to today’s ISDN or FDDI lines. However, not long ago POTS, which is also known as the public switched telephone network, was the standard telephone system across the world.

Processor drain: This is a term used to indicate a drop in the quality of VoIP phone service when a user opens several applications on his computer simultaneously.

Protocol: It is a convention or standard that defines the procedures to be adopted regarding the transmission of data between two computing end points. These procedures include the way the sending device should sign off a message or how the receiving device should indicate the receipt of a message. Similarly, the protocols also lay down guidelines for error checking, data compression, and other relevant operational details.

PSTN: PSTN, which stands for Public Switched Telephone Network, refers to the telephone system that transmits analog voice data. Till recently, PSTN was the heart of all phone systems worldwide. However, most of the developed world is now switching to or has switched to telephone networks that are based on digital technologies, such as ISDN and FDDI. RJ45: RJ45, which is the acronym of Registered Jack-45, is a telephone connector that is used in Ethernet and Token Ring Type 3 devices. It has eight “pins” or electrical connections.

Router: A router is a network device that that handles message transfer between computers that form part of the Internet. The messages, which are in the form of data packets, are forwarded to their respective IP destinations by the router. A router can also be called the junction box that routes data packets between computer networks.

Sampling: This is a methodology used to measure the value of an analog signal at regular intervals, and encoding it into a digital format for VoIP phone services.

Service provider: A service provider is a business entity that provides a communication, storage or processing service for a fee. Some of the service providers in the digital world are the Internet service provider (ISP), application service provider (ASP), storage service provider, mobile phone service provider, web hosting provider, and of course, VOIP service provider.

SIP phone: A SIP phone is a telephone that uses the SIP (Session Initiation Protocol) standard to make a voice call over the Internet. The SIP phones come with several value added services like voicemail, e-mail, call number blocking etc. There are no charges for making calls from one SIP phone to another, and negligible charges for routing the call from a SIP phone to a PSTN phone.

SIP: SIP, which is the acronym of Session Initiation Protocol, is an IP telephony signaling protocol. It is primarily used for voice over IP (VoIP) calls, though with some extensions it can also be used for instant messaging. It is less complex than H.323, the other IP telephony protocol.

Skype: Skype is a peer-to-peer Internet telephony company that revolutionized the way voice calls are made by using VoIP technology. The company, which has been acquired by eBay, was founded by Niklas Zennström and Janus Friis. Skype users can speak to other Skype users for free, but have to pay a small fee for calling or receiving calls from conventional phones.

Soft switch: It is a software application that is used to keep track of, monitor or regulate connections at the junction point between circuit and packet networks. This software is loaded in computers and is now replacing hardware switches on most telecom networks.

Softphone: This is a software application that is installed in the user’s PC. It uses the Voice over IP technology to route voice calls over the net and provides several value added features, such as call forwarding, conference calling, and integration with applications such as Outlook for automatic dialing The audio is provided through a microphone and speakers plugged into the sound card. The only limitation of a Softphone is that the phone call has to made through a PC. Many softphone are free VOIP software downloads.

Voice chat: This is an application that enables two or more than two individuals to carry on a verbal conversation over the Internet. Voice chat is also known as audio-conferencing or telephone conferencing on the net.

Voice over IP (VOIP): VoIP or Voice over IP is the technology that is used to transmit voice over the Internet. The voice is first converted into digital data which is then organized into small packets. These packets are stamped with the destination IP address and routed over the Internet. At the receiving end the digital data is reconverted into voice and fed into the user’s phone.

Voicemail: It is a telephone messaging system that digitizes the analog voice signals and stores them on disk or flash memory in a central computer. These messages can then be retrieved by users by logging on to the server or forwarded to another voice mailbox. Most voice mail systems have auto attendant capabilities, that is they can use prerecorded messages to route callers to the appropriate person or mailbox. Voicemail is usually a free feature in VOIP service plans

IM: IM, which stands for Instant Messenging, is a software that allows users to exchange messages in real time. However, to do so both the users must be logged on to the instant messaging service at the same time. Some of the popular IM services are: MSN Messenger, AOL Instant Messenger, Yahoo! Messenger, Google Talk and ICQ.

VOIP Gateway: This device provides the conversion interface between the public switched telephone network (PSTN) and an IP network for voice and fax calls. Its primary functions include: voice and fax compression/decompression, packetization, call routing and control signaling. It also provides an interface to Gatekeepers or Softswitches, billing systems, and network management systems.

VOIP PBX: VoIP PBX, which stands for Voice over Internet Protocol Private Branch eXchange, is a telephone switch that converts IP phone calls into traditional circuit-switched TDM connections. It also supports traditional analog and digital telephones.

VOIP Phone: A VoIP phone is one that uses the Internet to route voice calls by converting the voice data into IP packets and vice versa. The phones come with built-in IP signaling protocols such as H.323 or SIP that help in the routing of data to the right destination. A VoIP phone can also be a software application that is installed in the user’s PC. In this case it is known as the Softphone. Also, the calls in this case have to be made from the PC, and not through a telephone instrument.

VOIP services: The VoIP services are packet-based services that use the Internet to move voice data.
