How to make video calling

On this page, we look at video calling - the technology used to make voice and video calls over the Internet. The idea of having video phones in people's houses, or making video calls from mobile phones, is nothing new, but from 2006, there's a push to make house-to-voice video calling more popular - the magic ingredient being broadband Internet, which now makes person-to-person home videocalling practical.
BT Videophone 1000Video phone calling was first trialled a few years back over standard phone lines, but these lacked the bandwidth to support stable video calls. Now that more and more homes have moved over to higher-bandwidth broadband services, video calling is now possible in higher quality, and users of services such as MSN Messenger have been able to use webcams to do two-way video for a couple of years now.
In an attempt to make video calling easier and more accessible, BT has brought out a couple of videophones, to encourage less computer-savvy people to make use of video-over-Internet. To use these devices, you need to sign up to the free BT Broadband Talk service (free with BT Total Broadband). With BT Broadband Talk, video calls via your broadband connection can be made between two BT Videophones, a BT Videophone and a Softphone (on a PC with a webcam), or two Softphones used with webcams. If you're looking for advice on getting or using a videophone, hopefully we can help.

Videophones

In 2006, BT brought out two dedicated videophones that can be used to make video phone calls over broadband. We've been lucky enough to get hold of these handsets for review, and have been generally pleased with the results. The two handsets are listed below.
The Videophone 1000 and Videophone 2000 both make use of a Broadband connection for voice and video calls over the Internet, and BT are encouraging users to make use of their voice/video-ready BT Home Hub with BT's Videophones and BT Broadband Talk. These phones use something called Hi-dS (standing for High definition Sound) to achieve decent voice quality over the 'net, and in tests we did for our podcast, the quality of voice calls over BT Broadband Talk were pretty impressive (Take a listen to our tests in Frequencycast Show #08) .

BT Softphone

This is a free bit of software from BT, and if you've even used a PC Instant Messenger application such as MSN or Yahoo, you'll be familiar with the concept. The app is downloaded and installed onto your PC, and runs in the background. You can use it to initiate a voice or video call, using a microphone and/or webcam connected to your PC. The Softphone application can communicate with other PCs using Softphone software, or can make voice/video calls to phones such as the Videophone 1000 or Videophone 2000. You can also use the service for cheap voice calls over the Internet using BT Broadband Talk.
