I think one angle on the problem is to identify why RTPEngine is being
invoked twice for the same SDP (most likely the same SIP message).
That's best done by looking at the content of the reinvite itself. Focus
especially on the Request URI and the Route header.
I am not sure if the RTPEngine control module in OpenSIPS supports the
loop-protect option, or whether specific module support for any command
is required in order to use it.

Thank you

This happens when an SDP body that has already been passed to
RTPEngine, and already adulterated by RTPEngine, is passed to it yet
again.
Newer versions of RTPEngine have a loop protection feature to deal
with it. It involves injecting an unregistered a=rtpengine attribute
into the SDP, to say “I was already here”.
Most common cause on in-dialog requests (e.g. reinvites) is that
next hop is set to proxy itself due to RFC 2543 endpoint behaviour.
So, the proxy forwards the reinvite to itself and, unsurprisingly,
invokes RTPEngine again. Many times this can be fixed on the endpoint.

Hello Everyone,
I have a scenario, where opensips is working with rtpengine . Call
connects fine with audio.
I have enabled reinvite pinging to keep the call alive ; when the
reinvite is sent to both legs of the calls i get error messages
and NO AUDIO. The reinvite has full SPD body.
some config related:
modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:2123
<http://127.0.0.1:2123>")
modparam("dialog", "reinvite_ping_interval", 60)
record_route();
create_dialog("rR");
intermitent LOGS, until server is reboot:
rtpengine[21823]: ERR: Too many packets in UDP receive queue
(more than 50), aborting loop. Dropped packets possible
rtpengine[21823]: WARNING: More than 30 duplicate packets
detected, dropping packet to avoid potential loop
Any idea what might be wrong?
thanks you in advance!
