Internet Telephony(VoIP) in android
<p>Is it possible to build android app for voice call without any sever. Presently i saw the sample app in android which uses SIP. But that needs a SIP Server. Can we do similar work without the need of any server. I am afraid that if i use any server then the load on the server will increase a lot with increase in number of user. Correct me if i am wrong. Any possible approach to this?</p>
