Re: [SR-Users] Send 200 OK response with body to INVITE requests

Hi Alex, Thanks for the tip re: rtpengine routing, that's really useful. The flow I'm trying to create is like this: [ Test Client ] ------> INVITE ------> [ Kamailio ]          ^                                                   |          |-------------- 200 OK + SDP --------| The goal is for the test client to think a remote client accepted the call, when actually it's just Kamailio faking the 200 response. There must be some way (even if it's hacky!) to get a 200 response back to the client with the rtpengine SDP included? I got very close with $uac_req but it doesn't seem to be able to set the "200" status so the Test Client thought it was a brand new call. If I could set the 200 status with $uac_req (or something similar) then this will be working. Thanks.

A 200 OK to an INVITE transaction can only come from a user agent (endpoint), and Kamailio's sole job is to forward it. So, the 200 OK is going to come from the auto-answering callee. To engage RTPEngine in both directions, you need to intercept the 200 OK that is generated from the callee and call rtpengine_answer() / rtpengine_manage() on it: --- route {   ...   if(is_method("INVITE")) {       ...       rtpengine_offer("...");       t_on_reply("REPLY");       if(!t_relay())         sl_reply_error();       exit;   }   ... } onreply_route[REPLY] {   if(is_method("INVITE") && sdp_content())       rtpengine_answer("..."); } --- -- Alex On Mon, Apr 15, 2019 at 07:41:22PM +0000, David Dean wrote: -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
