How to implement voice & video chat [closed]

Question

I am working on a android application in which i have to implement peer to peer voice chat. I found in android this is possible in API level 12 or above because Google added android.net.rtp package in API level 12. By using this package we can implement peer to peer voice chat and video chat. But I need to implement this for API level 8. Now my questions are:

1. How i can implement this peer to peer voice chat for API level 8.
2. Is Jmf (java media framework) is compatible with android.
3. Is any other API available for android to implement this idea.

Answer 1

I suggest have a look at PJSIP opensource SIP stack. It isn't officially ported to Android, but some people have succeeded in using it on Android and have posted patches too.

The "csipsimple" project seems to be under active development.

http://sipdroid.org/ might be helpful too.
