Hello, We need to develop a SIP to Viber gateway. The gateway should be able to pass voice calls incoming over SIP and forward them through Viber to complete the call to the called party number. The development platform/operating system is not important. The project should be completed either by using the Linux/Windows Viber executables, or by using the Android /Symbian/ Windows Phone mobile versions of the application, no matters on the version number. The implementation should return the correct call error codes to the SIP backend, i.e. CALL SUCCESS, BUSY, UNAVAILABLE, etc. For a successful project we'll select the one, triggering successfully continuous SIP/Viber calls.

Dear Employer, Yes, we have worked on SIP/VoIP apps for android and iPhone both. In backend, we used Asterisk SIP server and on app part we used SIPDroid. We were able to establish call & responding with proper action code like Ringing, Busy Error & more. Kindly allow us to work on this application. Regards, Soniya Thakur
