I am having an issue when toggling between on hold (pause/resume) between caller and callee. I sporadically having an issue with the following exception thrown:
Failed to set local answer sdp: Failed to set local audio description recv parameters for m-section with mid='0'.
The SDP that was sent is as following:

I checked that for
m=audio 6577 UDP/TLS/RTP/SAVPF 9 126 (28 more lines)
this would also work
Does anyone know why the offer is not working for chrome, but it's fine for firefox and safari?
