Before you sign on to a VOIP service or plan, make sure that your broadband connection is up to snuff.

Voice Over IP (VOIP) needs a certain amount of bandwidth to be usable. Bandwidth is the amount of digital data that can be transmitted in a certain time period.

In general, an upload speed of 88 Kbps is recommended, although each VOIP service provider will have their own requirements.

You can test your current broadband Internet connection (provided through a cable or DSL service) using the free web tools. Here’s a couple to try:

• Vonage broadband speed test — automatically tests your upload and download speeds.
• TestYourVOIP.com — tests your broadband connection in a real VOIP call (requires Java enabled browser)

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.

Peter Csathy’s post on how SightSpeed runs things in the office is a great testament to how things CAN work if a company has the will. I started working exclusuively from home in 2003, but even before that point I remember having to negotiate hard to work even a few days out of the office–and that was as a contract tech writer. I mean if a contractor has trouble convincing management, an employee doesn’t have a hope. Since then, I’ve learned that it takes a certain kind of discipline to work effectively from home, and not everyone can do it well. However, with commute times for people edging up into the 4 hour range, companies have to start taking work-at-home scenarios more seriously. The impact of commuters on the environment is staggering as well. We need “to commute less and collaborate more — and more effectively — online”, as Peter puts it.

With tools like SightSpeed that are inexpensive and easy to deploy, there’s really no excuse for not entertaining a work-at-home policy. However, based on my experience, it hasn’t been the tools so much as the mindset. The biggest obstacle I see is a lack of skills or expertise in managing remote workers. It’s not the same as managing employees in the office. But there’s no training and no support, so managers operate the way they always have. It’s up to the remote worker to adapt and fit into the system. And guess what, there’s no support or training for employees to be fantasitc home-based workers either. In my view, you need both.

I just had a look at SightSpeed’s brand spanking new video community called Vlip, and not surprisingly, Peter the SightSpeed Guy is in there like a dirty shirt (or t-shirt, I should say). It looks like a sort of video message board where you can post your own videos and allow others to reply to you with their own cinematic responses. Just like SightSpeed, the video generation tools are built right in–all you need is a web cam.

They say it’s for adults only, 18 years and older, but I don’t know how they’ll enforce that exactly. The terms of use indicate they want to see respect for all opinions, but they will police the posts and take down vlips considered inappropriate.

You can read the official Vlip Manifesto on Peter Csathy’s blog (SightSpeed CEO). The VOIPGirl doesn’t vlip yet, but stranger things have happened.

Ted Wallingford got the scoop from Sightspeed’s Peter Csathy about their new and improved video mail feature. Faster, smoother, cooler. Gonna try it! 

Today SightSpeed went live with some great updates. If you’re already a SightSpeed user, you don’t have to do anything. All the new features will be there the next time you start the application.

Luca has already posted a great summary of what’s inside the new and improved SightSpeed so I won’t repeat. However, here’s a sample of the new video blogging feature. Rather than post a link to your video message, you can embed the video post right into your blog or web site. Great job!

By the way, to post this in Wordpress, I had to turn off the Rich Text Editor, and then paste in the code.

I recently bemoaned the fact that I was having a hard time recruiting followers to my SightSpeed network. SightSpeed is an easy-to-use video calling application that lets you make free video and voice calls.

I found that asking friends to join using the “Invite” feature generated an autoresponder-type email that at least one of my buddies deleted without even reading. It looked too suspicious.

Peter Csathy, SightSpeed CEO, points out that you can embed a click-to-call link in any email, or paste HTML code for clickable “call me” buttons into your web site or blog. The email recipient or web user clicks the link or button to launch a SightSpeed plugin that automatically dials you up. You’re not asking them to download or trial anything.

I tried it and it works great. At work, my husband could see and hear me, but I only had the audio. He also started a text chat while we were talking from his end.

To use click-to-call links or buttons:

1. In the SightSpeed window, click the Account button (top right).
2. In the Account Management menu, click Account Information > My SightSpeed.
3. Copy the Easy Email Link or Private Link code or copy the HTML code for the SightSpeed web button of your choice.
4. Paste the code into your email, web site, or blog.

 

Just noticed that SightSpeed has some basic parental controls. Yeah! See previous post on Kid Safety Online.

Log in to your SightSpeed account,  click Safety > Block Lists.

Looks like you can create a list of blocked users, either by email address or by community. Some onscreen examples would do well here. You then lock these settings by a password (Parental Key). Again, a better description of the type of key…letters, numbers, number of characters, would be useful.

I would also suggest an optional approach that lets parents specify a list of “allowed” contacts (such as friends, grandparents, cousins) and exclude everything else.

Hark ye, SightSpeed Guy…

You may have heard this before: Voice Over IP (VOIP) needs a certain amount of bandwidth to be usable. In other words, VOIP needs bandwidth so that voice conversations are intelligible by both parties. Your broadband Internet connection (provided through a cable or DSL service) provides that bandwidth.

Basically, bandwidth is the amount of digital data that can be transmitted in a certain time period. Internet connections are usually measured in KiloBits Per Second (kbps). Your connection may be rated at 512/128 kbps. This means that the upload stream (leaving your computer) has a maximum bandwidth of 128 kbps and download stream (coming to your computer) has a maximum bandwidth of 512 kbps. Find out the speed of your broadband connection…

For example, a web page that is 3000 bytes can theoretically viewed in 0.05 seconds – almost instantaneously - at a download speed of 512 kbps. However, in the real world web pages don’t usually load that fast.  That’s because data is held up, or delayed by various factors. Latency is the delay caused by the physical limitations of each piece of hardware the data is passed through. Delays are also caused by pathway congestion, error checking, transmission negotiations and extra data sent with the web page to identify its type, origin and destination.

What this means for VOIP is that enough bandwidth must be supplied to allow for the transmission of the actual voice data in real time as well as extra bandwidth for the overhead required for any data transmission.

So how much bandwidth does voice data use up? Well that depends on the codec (enCOder/DECoder) used to compress the data. Anywhere from 16 to 64 kbps is normal. Add onto that the extra overhead of about 10 to 24 kbps. In total, VOIP uses 26 to 88 kbps. As a general rule, assume that you will need at least 88 kbps to use VOIP reliably. Note that VOIP service providers will provide you with their broadband requirements.

You will need an Internet connection that can handle at least 128 kbps on the upload side. Extra bandwidth will allow others in the household to surf the net or download files while you are talking on the phone. If you wish to use conference calls even more bandwidth will be required.

While there is no set rule for the amount of bandwidth that a household will need, count on 128 kbps as a minimum.  If you have several computers and other devices connected to the Internet, consider going up to the maximum available.

Note that these speed are for uploads – the download speeds are usually quite a bit faster and present no problem for VOIP.
