Since Chrome M72, the default format of SDP generated by Chrome's WebRTC stack has been changed to "unified-plan" instead of  Google's old "plan-b" format, which has no been deprecated and planned to be removed sometime in mid 2020. Here are more details about it.

This poses a big problem for non-web WebRTC clients, servers and proxies (such as RTPEngine) which will stop working as soon as Google Chrome removes support for legacy "plan-b" SDP format.

In kmaialio's RTPEngine module, so far I have seen no support for this new "unified-plan" SDP format. 

Are there any support planed for future? 

Meanwhile, if there any way to add support for it in Kamailio via SDP manipulation e.g. SDPOPS module etc.

Thank you.
