Re: [SR-Users] No Media in SIP Incoming calls

Hello, Kamailio support 2 backend for rtp. RTP Engine and RTP proxy. it depends your configuration. I read from your post that  "I am not sure if this is an _RTP engine _issue and how to resolve this." . I thought it is rtpengine. Indeed , they are different services and has different configuration that do same thing that relays rtp packets.  you can find examples from documentation. I didnt get internal interface what is mean? but if rtpproxy/engine relays to Asterisk on -lo interface , you should listen your -lo interface by Wireshark. Good luck.

Maybe you mixed things? - Have you tried to capture internal interface of kamailio machine?
