Describe the bug

I use rtp_relay and siprec with rtpengine. Init rtp_relay and siprec in Request routing block and when from side callee come re-invite/update/... (change from <-> to) rtp_relay not access to rtpengine and not relay rtp to siprec (not modified sdp)

To Reproduce

Hold from side callee (change from <-> to)

Additional context

I am sorry, but I cannot understand what is being reported - are you saying that if the callee sends a re-invite, this does not get reflected in the outgoing re-INVITEs towards SRS? Can you please share a PCAP pointing out the issue?

I don't have the ability to attach a dump at the moment.

I'll try to describe what happens when the receiving party accepts a call and puts it on hold. re-invite arrives with an SDP and new RTP IP address, OpenSIPs passes this re-invite through (it doesn't change RTP IP address of rtpengine).

If the call originator puts the call on hold, OpenSIPs changes the RTP IP in re-invite and pass and rtp_relay forward media to siprec
