I need an app for android phones.
The purpose of the app (or other alternative) is to serve SIP ----> GSM gateway.
Calling should be automatic - No human intervention. The app should be capable of working continously 24/7 dialing out calls as they are received.
The phone will receive the SIP/VOIP call through the data cable while normal GSM SIM card will re-originate the call.
The app should be able to keep daily cumulative call statistics.
I want to speak to expert android developers who have already done a similar project and have some samples to show how they are working.
