We are a VoIP provider who is looking for a SIP IPhone/Mobile phone dialler with source and the following features:
1. UI could be very similar to Fring
2. Must supports G729 or G723.1 and G.711 codec
3. Can run behind NAT
4. Should be accessible from 3G and WIFI
5. Subscribers should be able to call each other (PIN-PIN calling), check balance and call history.
6. TLS support for encrypted SIP would be a plus
