Symmetrical negotiation
by Diego Carvalho 19 Jun '12

Hi all, Does anyone know if there is a way to wait the remote endpoint's OLC message before sending ours? I want to make the negotiation symmetric (have same codecs) and also video payload type (e.g If remote sends pt = 96 in its OLC I also want to send pt = 96 in my OLC). So that's why I need to wait remote's OLC first. I appreciate any help. Thanks.

Hello Mark, Thanks for the info! I also have another question about H.239, I am testing simple-application now, after connection and when I type "S" in callee-side(to start H.239), I got error message said "Application Open Error: Remote may not support Feature!", does it mean I need to enable H.239 capability in caller-side first? could you tell me how to make a H.239 enabled call with simple-application? do I need to modify the code of simple-application or just update the configuration? Thanks!
