I want to make a bandwidth efficient voip dialer. Cant seem to make up my mind about which protocol to use. I see 3 main candidates SIP, H.323, IAX2. Can anyone please suggest me what to use and why? Also possibly some links or books to read more 🙂

Most flexible and best Protocol is
SIPand easy to build.H.323is the most complex and difficult to build.There is Demo App in Android API level 15 Samples folder called
SipDroidProject which comes with android API 15 Level.You can go through that project.
