Hello List, I'm having an issue with rtpengine changing the source port of the RTP stream after receiving a 183 from the carrier. Though RTP engine continues to send RTP to the proper carrier IP and port the carrier drops the inbound audio once the source port changes. Can anyone tell me what might trigger this type of behavior from rtpengine and if it's expected? Thank You, ___ John Petrini _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
