[sr-dev] mediaproxy-ng failed to rewrite sdp from jssip ws client

[Juha Heinanen]

i tried what happens when i make rtpproxy_answer("co2sp") call on 200 ok
from jssip ws client.  mediaproxy-ng replied with failed to rewrite sdp
error.  i don't know if there is something wrong in jssip sdp or if
there is a bug in mediaproxy-ng.
