Android Dialer to receive SIP calls via internet Connection and dial call from the phone.

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.

Kĩ năng: Android, Java, Mobile App Development, VoIP
