[Freeswitch-users] In proxy_media mode, RTCP is not proxied or activated

[Richard Chan]

Hi list,

Is there a way to force FS to activate RTCP and rewrite SDP  to
a:rtcp:<freeswitch_ip_address> in proxy media mode?


Testing FS 1.6.15 in proxy media mode with two pjproject-2.6 pjsua clients.
FS is not rewriting rtcp lines.

In SDP,
c=   # correctly rewritten to point to FS.
a=rtcp: # not pointing to FS, but as the UAs sent.

switch_rtp.c:switch_rtp_activate_rtcp() always exits early as ms_per_packet
is 0



####################

The dial plan has

<action application="set" data="proxy_media=true"/>

Both UAs generate rtcp lines in SDP
