Hi, This is Awais. I have read your requirements and understand it. I was recently working on SIP based project and doing the calling part in that. I was successfully able to achieve the task by using open source Linphone Library in Android.

Our softphone solution is a standalone client-side software VOIP phone application and is not bundled together with a VoIP service. To make and receive VOIP calls using our Solution, you must subscribe to any SIP or IAX based service provider across the globe. Our Solution key features include: - Support for different color schemes - Bluetooth support - Lowest battery usage with highest reliability/stability on google play - Lowest latency of all android softphones - Excellent audio quality, even on older devices - Supports calling over 3G and WIFI - Multiprotocol with SIP and IAX support, compatible with all RFC compliant PBXs - Background/multitasking support - Native dialer integration - Integration with the native android contact list - Speakerphone mute and hold - UDP and TCP transports (use TCP for better battery life!) - Supports g711 (ulaw, alaw), Speex, iLBC and gsm codecs - Supports sending of DTMF - DNS SRV - Built-in echo cancellation - STUN support - Change ringtone per account - call waiting - Video support - ZRTP / TLS support - Call Transfer - Wideband audio Please let me know your view to proceed and discuss this project in detailed. Anticipating your prompt response looking forward to hearing back from you
