Hi,

I am trying to understand the expected behavior of latest FS when the client sends SDP offer with RTP BUNDLE and uses the exact same IP + port combination for both audio and video media components. Is BUNDLE (https://tools.ietf.org/html/draft-ietf-mmusic-sdp-bundle-negotiation-39) supported by FS? If not, can you pls let me know the when it is planned to add the support for the same?

I am seeing the below errors in fs_cli. Can you pls confirm if the issue is because BUNDLE is not supported by FS?

2019-06-12 07:01:03.143578 [DEBUG] switch_core_media.c:3236 alternate payload received (received 96, expecting 111)

Here are the relevant SDP m and a lines from the client's offer:

a=group:BUNDLE audio video

....

m=audio 9 UDP/TLS/RTP/SAVPF 111 103 104 9 0 8 106 105 13 110 112 113 126

a=mid:audio
