Hi FreeSWITCHers, I think I may have found a bug in FreeSWITCH regarding video forwarding in a call center configuration. Basically, when an extension calls a call center number (setup with mod_callcenter), and a call center member replies to the call, FreeSWITCH may end up forwarding video with a wrong RTP type once it has connected both legs of the call. This error is dependent on the codec configuration of each part. This happens e.g. when caller has H.264, when callee has H.263 and H.264, and when FreeSWITCH is configured with H.263 and H.264 (in this order). In such a case, FreeSWITCH initially negotiates H.263 with the callee, and ultimately, it ends up forwarding H.263 data from the callee to the caller, but it erroneously re-tags it as H.264 at RTP level. Since in this case, H.264 is the common capability of all participants, perhaps a H.264 renegotiation should have been initiated by FreeSWITCH before beginning to forward data? I have created FS-6640 on Jira to describe this issue, including an attached Wireshark trace. Please refer to this bugnote for details. Many thanks in advance for having a look. -- JPI
