i'm new it this area .
i'm trying to write sip client in j2me on s60 according to http://dev2dev.bea.com/pub/a/2005/09...ip-part-1.html
just for the clarification the process is "register" (with the proxy server) , then "invite" .the voice is handle by the sdp string that actually set the encoding
on rtp ... am i right or i'm missing something
