Talkster: VoIP App for Facebook

Talkster, the makers of a cool VoIP app, have now released a Facebook application. The original Talkster app lets users make free calls over the internet, but, unlike other VoIP apps like Skype, Talkster users make free calls to voice-enabled IM services. From your web-enabled mobile phone, you can call some on your IM buddy list. From the Information Week article on this app, Talkster gets rave reviews:

Talkster pushes the VoIP envelope in the direction of presence, the ability to see whether the person you want to communicate with is online, and how. Once you’ve set up your voice IM contacts in Talkster, you can see your buddies’ presence information from your mobile phone’s browser. (Talkster does this without installing any software on your phone, either.) …Talkster’s technology has an immediate benefit — it lets you pick the least expensive way to reach your contacts — and it’s got long-term potential as well, because voice communications are moving away from reliance on the 10-digit telephone number and over to Web 2.0 addressing schemes, such as IM handles that can be resolved to IP addresses. Talkster is positioning itself for the future.

Now, with the Facebook application, you can use Talkster and the Free World Dialing application to make free calls to friends or groups of friends from your mobile, your home phone or wherever. To get started, just add the application, send your friend(s) an invitation, and start calling immediately.
