Hello All, I am trying to integrate the file transfer mechanism in pjsip. First of all is it possible to use the TCP hole punching mechanism for this? I am looking for the location as to where in pj-sip TCP/UDP hole punching is done ? Is it done when UDP transport is created also for TCP when TCP transport is created ? Thanks and Regards Sachin -------------- next part -------------- An HTML attachment was scrubbed...
