Hi all, Currently I'm using pjsua API for my application. In my application, I would like to check for incoming instant message and extract the message from the MESSAGE packet. However, I have no idea on how to detect an incoming sip message from my application. Is there are any function that can return the status of incoming message so that I can check for it? I had read the PJSIP Developer's guide, in http://trac.pjsip.org/repos/wiki/SIP_Message_Buffer_Event. there said that RX Message Event is the event that a packet of sip message is coming. But I don't know how to check status of it. Can anyone give me some help? or how to check for an incoming event? Any help is appreciate. Thanks :) Sincerely, ws -------------- next part -------------- An HTML attachment was scrubbed...
