Hello,

is the call looped via rtpengine twice? Like

UA1 ---- K+RTPENGINE ---- SIP Server ----- K+RTPENGINE ---- UA2

Cheers,
Daniel

>> Problem here is that - in first event kamailio terminates the call, hence when second event comes, kamailio says - call-id not found and send response back to RTPEngine. But still RTPEngine keeps sending that event message for three more times. Kamailio has to respond to it with call-id not found. Which is overhead. Not recommended for production environment.
