Group test: what's the best internet telephony software?

Save money with the best VoIP services

PC Advisor reviews the best internet telephony software you can use in the UK right now.

5. Jajah

Anyone who wants cheaper international calls without being tied to a PC should give Jajah a try.

4. Google Voice

Google Voice has so many features that we've barely scratched the surface of what it can do. Is it worth trying? Absolutely. Since it's free, you've got nothing to lose by giving it a whirl.

3. Skype 4

With a VoIP program such as Skype, improved voice and video quality trumps dubious interface changes any day. So we are moving to Skype 4.0. That said, some Skype users might want to skip this upgrade. If you're content with the call quality of your current version of Skype, you're happy with its look and feel, and you'd miss Skype's public chats (the new version doesn't let you add new ones), consider staying with the version you have. And of course there are competing services, such as ooVoo, to consider.

2. Sipgate

Sipgate is a good bet for those looking for a VoIP service that isn’t tied to their PC and doesn’t require a separate handset.

1. Vonage

Vonage is the perfect VoIP service for international callers who want to personalise the countries in their VoIP subscription. Recommended.
