Hi all,
I tried to implement simple announcer by using play_media function in
latest rtpengine module. I implemented simple Lua script and I tried to
test the implementation with simple SIPp scenario.
Here is the Lua function to reply the received INVITE request.
```Lua
function ksr_route_announcer()
KSR.info("======= Announcer =====\n");
local u = KSR.pv.gete("$rU");
KSR.info("username is: " .. u .. "\n");
if u == "ann" then
KSR.info("announcer has been called.\n");
if KSR.textops.has_body_type("application/sdp") then
KSR.info("request contains SDP.\n");
KSR.tm.t_newtran();
KSR.rtpengine.rtpengine_manage0();
KSR.tm.t_reply(200, "OK");
KSR.x.exit();
end
end
end
```
According to kamailio logs rtpengine modified the INVITE SDP, but I want to
add SDP to 200 OK response. How should I manage rtpengine to append SDP
answer to the 200 OK response?
The attached is the SIPp log, as you can see that last 200 OK doesn't
contain SDP.
Regards,
Ali
