Hi Benny, et al, With your help (thanks a lot!) and from the sample stateful_proxy.c, I was able to create sip server which does registrar and proxy functions. This setup allows two soft-phones to registrar themselves and make calls between them. However the rtp stream for the call is established directly between the User Agents and not via the sip server. Hence I would like to know what changes should I have to perform to make the rtp go through the sip server. Appreciate your help. Thanks, Senthil. ____________________________________________________________________________________ You rock.
