Hi, I'm trying to build a script for early media. I've kamailio 5.6 and rtpengine 11.3.1 on my server. I just want to play local media when I get call to my server but its not working as I want.

<!--

I've configured kamailio to work with rtpengine and added this snippet to " onreply_route[MANAGE_REPLY] " section.

if(status=="100") { rtpengine_manage(); t_reply("183", "Session Progress"); block_dtmf(); play_media("from-tag=$fti file=/usr/share/rtpengine/decode_G711.wav");

I can see the RTP is playing successfuly but the kamailio is not creating SIP messaging with SDP to play on other side.

 

I couldn't figure out how should I configure, can you please advise me about that?
