[OpenSIPS-Users] rtpproxy_answer issue

Hi Seth,
It seems to be becuase the 180 and 200 replies you get are already using
another rtpproxy (somewhere after you, on the SIP path) - see the
"a=nortpproxy:yes" marker in the received SDP.
So rtpproxy_answer() sees that marker and does not try to do anything
again (returning -1). To force the insertion of RTPproxy, use the "f"
flag in rtpproxy_answer() or set the "nortpproxy_str"
(http://www.opensips.org/html/docs/modules/1.8.x/rtpproxy.html#id250242)
to empty string.
