I use jmf library to make a client on PC, this library seems to provide 3 RTP audio codec supports. They are
ULAW_RTP, GSM_RTP, and Gxx_RTP.
About the client on Android, I customize the source code from SipDroid and run it on Galaxy Tab device. But it just support two codecs - PCMA and PCMU.
My problem is that the client on PC can understand the packet sent from Android, but not vice versal. And two Android devices can understand. So I wonder that if Android supports those codecs which are provided by JMF as mentioned above?
Anyone experience on this ? I need your help.
