SIP Mobile Dialer (iPhone, Android, Symbian) with VPN Tunnel (Relay Based)

Best Example for what I am looking for is Zoiper App only additional feature I am looking for is tunneling (Relay Based)

We are looking for a mobile dialer(Full source code) SIP or H323 (SIP is preffered) which can run on

1) User friendly interface

2) Mobile Dialer should support SIP/H323 for signalling.

3) Mobile Dialer supports G729, G723.1 and [url removed, login to view] codec for sending audio stream

4) Mobile Dialer can run behind NAT or on private IP with VPN Tunneling embedded (Relay Based)

5) This software will run on the phone having iPhone, Android Symbian or Windows Mobile 5 and 6 having internet via GPRS/EDGE/Wi-Fi/3G and all other available OS and Phone models.

6) Mobile Dialer should be fully customization.

7) Able to use Mobile Dialer with any kind of Softswitch,Voip Billing Platform which support SIP/H323. (VOS, VoIP Switch)

The dialer must be runing from the application layer. The most important part is to add G729,G723.1 codec and Tunneling in it.

Very important part of this project is to add tunneling feature so call can placed even where VOIP protocol (SIP/H323) is blocked.

Example of Mobile SIP Clients === MobileVoip, Siphone, Rynga, Fring sip clients and SKYPE.

If network is not present and user wants to use voip calls from provider then application will automatically dial access number of provider through GSM network to connect provider calling card or callback system.
