Luca got the scoop on this one this morning. (Or is it afternoon for him?) Fring now works with SIP services like Gizmo Project, VoipCheap, VoipStunt and Free World DialUp. It’s still in beta mode, but I’m going to download it today and see what’s what (handy to do on my Nokia N80i).

Fring is a free application for your mobile phone that lets you talk with fring, Skype, GoogleTalk, MSN and now SIP-based applications over VoIP, GSM, WiFi and PSTN networks.

I’ve used it most with my Skype buddy list. On my phone, I can see who’s available on Skype and who’s not, etc.

At present, fring is only available on certain Nokia handsets (Symbian 8 - Series 60 and N Series phones). See a visual list of compatible handsets on their web site (look under “Minimum Requirements”).

Truphone is a UK software developer that has just released free VOIP software for Nokia E series cell phones. Mobile calls are free forever to other Truphone users and, until the end of the year, free to landline phones as well. For Truphone to work, you must have Internet access to a Wi-Fi network, which means your home, coffee shops, and public access points, among other places.

The company also resides on an all organic farm in Kent, UK, which I think is kind of cool. Their web site is well documented from a user point of view, so if you’re thinking of giving it a try, click the Help tab and have a look the Frequently Asked Questions and How-to-Guides.

Just a phew PhoneGnome tips to pass along:

What if your Internet goes down?

Okay, like my Internet never goes down except that it DID right at the exact moment I went to make a phone call. My PhoneGnome (actually the phone connected to PhoneGnome) wasn’t giving me any dial tone. According to David Bekenmeyer, top gnome over at TelEvolution, PhoneGnome takes a few minutes to detect that Internet has disappeared. DO NOT panic. Wait a few minutes and your PhoneGnome will switch over to PSTN mode and give you dial tone.

But what’s with the Phunky Dial Tone?

If your Internet goes down and your PhoneGnome switches to PSTN mode, you’ll hear a phunky sounding dial tone, higher pitched than normal. It’s not a malfunction. You can make regular landline calls just fine. The PhoneGnome folks thought that a distinct dial tone would be helpful in alerting you to the fact that Internet calling is temporarily unavailable. If you find this feature alarming rather than reassuring, let them know. The TelEvolution support gnomes are very receptive to feedback so your ideas are welcome.

Why is there a ring delay between my PhoneGnome and the other phones in the house?

This I noticed right away. When I receive an incoming call, the upstairs phone rings twice before the PhoneGnome starts ringing. It was bizarre to hear the ringing out of sync. Almost sounded like two separate calls coming in. What’s happening is the PhoneGnome needs a bit of time to collect caller ID and other information before passing the call through. The best way to solve this is to put all your phones in the house on PhoneGnome. For $19.95, you can buy a Whole House Wiring kit that uses the Line 2 wiring to distribute PhoneGnome features to all your phones in the house. If messing with wiring isn’t your thing, an easier and inexpensive option is to buy a cordless telephone with multiple handsets.  Connect the cordless phone base station to PhoneGnome, and deploy the extra handsets around the house.

 

 

Alec Saunders reviews Talkster, a new service that lets you make inexpensive cell phone calls anywhere in the world, and mobile to IM (Instant Messenger) calls. In Talkster’s words: “There are a couple of cool perks to note with the Talkster service; some of the most important being that there is no subscription to the service to buy (ala Rebtel), there is no software to download (ala Jajah), it works on the cell network you are already used to using (no 3G requirement ala Fring), and it works on the phone you already have today (not just select Java phones). It also works today, with popular IM services MSN, GoogleTalk, and Gizmo Project. In a nutshell, Talkster is the first company to enable mobile-to-PC Voice over IM (VoIM) calls, that works without software, on virtually any phone.” That sounds like something worth trying.

Alec reviews it using his Blackberry and he’s impressed by how easy it is to browse his list of contacts, view their online presence, and make calls. While the service works without software on virutally any phone that supports a browser, in reality only browser-friendly phones need apply. For example, my cell phone has a browser, but the phone itself is of the entry level variety so using the web enabled capabilities is awkward (I find). I’ll be giving Talkster a try with my basic handset and with my husband’s fancy one and I’ll add my comments to the mix.

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.

Carolyn Schuk from Voxilla has an interesting post on TelTel, who she calls one of IP communications’ best kept secrets:

“With an estimated 2 million registered international users for its service, TelTel is probably one of the best-kept secrets in VoIP. By comparison, Jeff Pulver’s much better-known Free World Dialup, has some 600,000 users.”

Now, two million is a pretty big number so I thought I’d give the TelTel softphone a try (I’ll be honest and say I hadn’t heard of them unitl now).

I was pleasantly surprised by the packaging. The software has a nice look and feel to it and I think the installation and account setup really have the novice user in mind. For new users, the first tip of the day is a handy glossary of screen symbols. Unfortunately, there’s no way to find it again once you dismiss the window. Oh well….

Further exploration of the software revealed a few problems. I experienced delays and serious hang-time as I clicked various screen elements and links (such as Buy Credit, Help and the user forum of all things). Plus, when I tried to make a call, I got the add contact dialog box instead. 

I’m also not sure what’s free about this service and what’s not. TelTel subscriber to subscriber calls are free, and TelTel to landline phones are subject to low calling rates (nothing new here), but what about TelTel to SIP phone numbers, or SIP phones to TelTel?

While the marketing message is that TelTel is Skype-like but SIP-driven, I’m going to stick with GizmoProject until this softphone lives up to its looks.

Katie Fehrenbacher at GigOm has a good summary of what’s going on at the big mobile conference in Barcelona 3GSM. She picks the top stories from the big players and notes that entertainment and content providers are new trends getting some notice. Check it out. Phoneboy finally also gets to add his two cents about the Nokia phones launched at 3GSM. His fave… the E90 Communicator.

I’ve just got home from an inspirational but exhausting weekend at the Surrey International Writer’s Conference. Sorry folks, no blogging here, IP whats-its, new-fangled phones, gadgets of any kind (can you imagine?), or mobile VOIP. Just 800 enthusiastic writers, editors and agents from all over North America. What  a blast!

So next year, if you feel like rubbing shoulders with the likes of Bernard Cornwall and Diana Gabaldon, or better yet, if you’ve got a novel that’s been simmering inside you for years waiting to make a dramatic entrance, then see you in Surrey, BC (Oct. 19-21, 2007).

When shopping around for a VOIP phone, no doubt you’ll come across buzzwords like: softphone, SIP phone, IP phone, and Internet phone.

Do all these terms mean the same thing, or is there a difference? Let’s take a look.

VOIP phone or Broadband phone: A handset used to make VOIP calls. A VOIP phone has an Ethernet port (RJ-45) instead of regular phone jack (RJ-12), and they connect directly to a broadband Internet modem. A VOIP phone does not require a computer or softphone application to make or receive calls. A high speed Internet connection and subscription to VOIP phone service is all that is required. A SIP phone is a type of VOIP phone.

SIP Phone: A VOIP handset that complies with the SIP standard for voice over IP. SIP is the latest open standard, succeeding H323 standards. Bottom line, SIP compatibility is good. Phones that compete with SIP use proprietary signaling protocols for voice over IP. SIP softphones are VOIP software applications that comply with SIP standards.

IP phone: An umbrella term but used to mean any phone that can be used on an IP network (like the Internet). An IP phone may comply with either proprietary or open standards for voice signaling. An IP phone doesn’t have a RJ-12 connector like regular phones.

Internet phone: This term is used pretty loosely and depending on the context can mean the same as IP phone.

Softphone: A software application that lets you make calls over the Internet using the mouse or keyboard to dial phone numbers. To use a softphone, your computer must have an sound card, plus a speakers or headset, and a microphone. A USB phone can take the place of headset and microphone. Softphones are often free to download. Free VOIP software such as Skype and Free World Dialup are two popular choices.

USB phone: A handset that connects to the USB port on your computer. It is used for convenience when dialing from your computer, but it requires that a softphone application be installed first. Instead of using the softphone with a headset or microphone, the USB phone looks and acts like a regular phone and keypad. USB phones require driver software to be installed on the computer.

WiFi phone or WLAN phone: A handset used for making wireless VOIP calls. It has a  built-in WiFi transceiver unit instead of an Ethernet port. When you talk over WiFi, the phone connects wirelessly to a WiFi base station and from there to the Internet and a remote VoIP server. A computer or softphone is not required to make and receive VoIP phone calls. All that is required is access to a WiFi base station. Many cell phone companies are developing handsets with WiFi capability. This means you can make calls on the regular cell phone network and make VOIP calls on a local WiFi network (called a WiFi hotspot).

Skype phone: A handset that is much like a USB phone, except that the softphone application used to make the calls is Skype. A Skype phone can only make calls using the proprietary Skype phone software running on your computer. Linksys recently announced the release of its CIT200 wireless Skype handset which makes using Skype convenient from anywhere in the home.

Web phone: A marketing term that has been used to mean many things, both softphone and IP phone-related.

Net phone: Same as IP phone

Computer phone: See softphone, PC phone or USB phone.

PC phone: See computer phone, softphone or USB phone.

In order to use VoIP, both parties need a broadband connection. This is a high-speed Internet, or broadband connection usually provided by a cable or DSL modem. Broadband modems are usually used to connect computers to the Internet, but in the case of VoIP, computers are not necessary.

The simplest form of VoIP is a computer-to-computer voice connection. All that is required for this type of connection is a computer, a headset consisting of earphones and microphone, and VoIP software. Most software packages are free and allow you to connect to any computer running the same software. There is no charge for this type of connection and calls can be made to anywhere in the world.

VoIP software can also be used to connect to land-line phones — that is, phones which are not connected directly to the Internet. This type of call is usually not free but the cost is quite a bit lower than what your telephone company charges. Some VoIP services also allow you to make calls to cellular phones.

The only time that both parties need a particular VoIP software package is when they are making computer-to-computer calls. Parties receiving land-line or cellular calls do not need any extra equipment or software.

VoIP Transmissions

VoIP is based on digital data transmission. The first step in any VoIP call is to convert the analog signal of the human voice into digital data. This is done within an Analog-to-Digital Converter (ADC) that divides an analog signal into discrete steps which are represented by numbers. The next step is to compress the audio data using a codec (enCOder/DECoder) which significantly reduces the amount of digital data while maintaining audio quality.

The compressed digital data can now be sent over the Internet. The data stream must be divided into packets which, besides containing the audio data, also have information concerning their destination and their place in the data stream.

All data that is sent over the Internet is encapsulated in ‘layers’ which aid in its proper delivery. For example, web pages may use the Internet Protocol (IP) network layer to specify destination and origin addresses, the Transmission Control Protocol (TCP) transport layer to create a connection between two computers and the Hyper Text Transfer Protocol (HTTP) as an application layer to allow the Web browser to display the web page correctly.

Most VoIP uses a transport layer called User Datagram Protocol (UDP) which is faster than TCP. A commonly used application layer is Real-time Transmission Protocol (RTP) — originally developed for delivering audio and video over the Internet. RTP provides information about the sequence of the data packets so they can be reconstructed in the correct order at their destination.

RTP also has the ability to drop packets if they do not arrive within a certain amount of time. This is necessary for telephone conversations because if the telephone software waited for every packet of information to arrive before reassembling it there would be unacceptable delays in the audio stream.

Even though some of the packets are dropped, there is usually still enough information to make the conversation legible. The number of packets that will be dropped depends on the speed of your Internet connection in the distance between the two parties.

Once the voice data has arrived at its destination, it is reassembled in the correct order and converted back from digital to analog.
