[OpenSIPS-Users] mediaproxy/rtpproxy problem with reinvites

[Jeff Pyle]

It seems like this has less and less to do with routing logic and more to do with the timing of packets arriving at rtpproxy.  It seems like this:  if no RTP packets arrive at an established rtpproxy session before the session is reinvited and re-established, the re-established session will fail in both directions.  However, if at least one packet arrives at the original bridge, the reinvited session will also work.

Does that make any sense?

Makes sense to me.  I have several to choose from.  :)

In the in-dialog section, if I replace your force_rtp_proxy("l") with an unforce-then-force (no flags), I can restore the on-net operation.  It seems to work 100% of the time.  However, on calls from my PSTN gateway to the NATed user (via Asterisk), it works about 20% of the time.

In every case the SDPs for the invites and reinvites look appropriate.  As such, all the gateways and UAs engaged in the call send RTP to the proper place (to rtpproxy).  The problem seems to be where rtpproxy relays the RTP, if anywhere at all, after the reinvites take place.

At this point, the most efective is to capture a SIP trace and examine it.
