hello i read the documentation about RTPengine.and the documentation says that: If INVITE with SDP, when the tm module is loaded, mark transaction with internal flag FL_SDP_BODY to know that the 1xx and 2xx are for rtpengine_answer() what does it mean? actually - according to 3261 RTP media (both ways) may be turned on after ACK

what does it mean?
This is taken from the rtpproxy module. For SDP negotiation, there are two basic scenarios:
1) SDP "offer" in the INVITE and SDP "answer" in 1xx or 2xx, or 2) No SDP in the INVITE, but SDP in 1xx or 2xx, which becomes the SDP "offer," followed by the SDP "answer" in the ACK.
The flag is used for _manage() to be able to distinguish between these two cases, in particular whether the SDP in 1xx or 2xx is an "offer" or an "answer."

[SR-Users] question about RTPengine
Does it mean that rtpengine_manage() determine the session state itself? i.e it is not needed to find out in the configuration file that INVITE contains SDP or not because rtpengine_manage() determins internally what this INVITE is? am I correct?

When I make internal call between 2 internal subscribers (yate softphones). The subscriber B answeres, after all the Kamailio/rtpengine sends a 200ok reply to the subscriber A, but the softphone does not recognize it (it does not ACK it). I think it is because of its SDP which the RTPENGINE replaced with it's one.
is it possible to instruct the RTPENGINE not to insert these extra lines or should I use, say LUA, to remove these extra SDP lines.
What is the correct way here

Hi when I try to remove these extra SDP line I insert the following code to the script:in INTERNAL_REPLY onreply_route if($T_reply_code=="200") { if(has_body("application/sdp")) { xlog("L_INFO", "RTPENGINE received internal reply $T_reply_code $rr SDP extra lines will be removed"); set_rtpengine_set("0"); rtpengine_manage(); replace_body_all("a=rtcp.*\r?\n",""); replace_body_all("a=ssrc.*\r?\n",""); replace_body_all("a=ice.*\r?\n",""); replace_body_all("a=candidate.*\r?\n",""); xlog("L_INFO", "RTPENGINE received internal reply $T_reply_code $rr SDP extra lines removed"); } } This code does not work as expected. SDP lines are not removed. does this approach is correct or should it be done some other way?
