It would help to see the SDP from the offer as well, most like the problem can be found there. Currently there's a known issue when the offer SDP contains multiple streams multiplexed on the same RTP port, i.e. audio and video (and also RTCP) on the same port like Chrome does it. This isn't trivial to fix in the current code base, but I have a more severe rewrite planned that will address this issue. Until then, the only workaround is to disable video.
cheers

It would help to see the SDP from the offer as well, most like the problem can be found there. Currently there's a known issue when the offer SDP contains multiple streams multiplexed on the same RTP port, i.e. audio and video (and also RTCP) on the same port like Chrome does it. This isn't trivial to fix in the current code base, but I have a more severe rewrite planned that will address this issue. Until then, the only workaround is to disable video.
below is both offer and answer.
I think the problem is that the offer doesn't contain a=rtcp (i.e. RTCP is on standard RTP+1 port), but the answer did and had it running on different ports (not RTP+1). Just like the multiplexing case, this isn't properly handled by mediaproxy-ng yet, but will be once I get the rewrite of the stream/port handling in.
