JAJAH brings telephone call to twitter

JAJAH, VoIP (Voice Over IP) provider will allow its users to make free calls using Twitter. The service is started in beta now.
Note both the caller and the callee needs to be part of the @Call service. So how does it work?
From twitter, you tweet: “@call @username” using the twitter username of the person you wish to call.
If you are logged in to twitter from a PC, you phone will ring, once you answer, the call will be placed you will hear a message “Please hold, JAJAH is connecting your call…” and you wait for the person to pick in the other end. You can also try it from your mobile phone.
JAJAH will connect the call without reveal contact information to any party. For privacy reasons, calls can only be made to followers.

The free call is only 2 mins long and according to JAJAH it is the voice equivalent of a text tweet. I think they figured out a nice way to say “we can only afford 2 mins for free, please buy credits to talk more”, but anyway it’s a good marketing campaign that will probably lock some businesses. This is at least JAJAH’s expectations.
Hopefully JAJAH@Call won’t cause any further downtimes on twitter’s servers if everyone wants to benefit from Free Calls.
