This can happen if the output SDP (rewritten by rtpengine) is fed back into rtpengine as an input SDP for the same call/branch. Then rtpengine will start looping media back to itself. There are some safeguards in the code to prevent this from happening, but if the underlying signalling is broken, it can still happen.
Ah, I see. Thank you for that insight.
I have trouble visualising where in our Kamailio config this could happen, but I suppose it's not impossible. I'll try to identify that case.
