Jili

Jili, this bird can talk!

Jili lets you receive or make voice calls using your twitter @names and #tags without needing a phone number. Your username is your phone number and #tags lets you have a voice "huddle" with many other twitter users at the same time.

You can control who is allowed to call you, followers, those you follow or anyone. Or create a voice #tag for your followers to join you on a room like a conference call.
