peter,<br>
<br>
when jssip client calls regular sip client, i made the same<br>
rtpproxy_offer(co1spr)/rtpproxy_answer("co2SPr") calls as before, and<br>
rtpproxy_answer resulted in the same error as before. (below)<br>
<br>
my mediaproxy-ng is from current git master.<br>
<br>
how does your tests differ from the above, since you have got it<br>
working?<br>
