Hi.

It is not just an issue of supporting codecs, but also to preserve certain information inside the SDP like QoS and BandWidth.

Without proxy-mode, many of the info in the SDP description (an example here) are removed from incoming to outgoing INVITE.

Hi

These days FreeSWITCH has full support of video codecs and t.38. There is no point of using proxy mode or putting any efforts in it.

Hi all.

On February last year there was a discussion related to proxy_media mode and RTCP and I understood this is not actually supported.

I am actually facing the same issue and I would like to understand if there is any way to get it working; since RTP is using an even port and RTCP the following one (RTP port + 1), is there any way to get both ports proxied?
