Hello!
I'm trying to remove m=video stream from incoming SIP/SDP request in th way below:
modparam("rtpengine", "read_sdp_pv", "$avp(read_sdp_pv)") modparam("rtpengine", "write_sdp_pv", "$avp(write_sdp_pv)") ... sdp_remove_media("video"); msg_apply_changes(); sdp_get("$avp(read_sdp_pv)"); xlog("L_WARN","[$cfg(route)] *m=video removed* ci| rb=/$rb/ \n"); xlog("L_WARN","[$cfg(route)] *m=video removed* ci| avp(read_sdp_pv)=/$avp(read_sdp_pv)/ \n"); rtpengine_manage("$avp(rtpengine_offer)"); set_body("$avp(write_sdp_pv)", "application/sdp");
But no luck, xlog shows m=video in $rb and $avp(rtp_sdp_read) as well.
Hello,
run with debug=3 and what the logs to see if there are error/warning messages.
Cheers, Daniel

Hello,
probably you have to use the function that has the country code:
- https://kamailio.org/docs/modules/stable/modules/phonenum.html#phonenum.f.ph...
Because the number is not in international format.

Got message in debug=3: *13(2141) ERROR: textopsx [textopsx.c:181]: ki_msg_apply_changes(): invalid usage - not in request route or a reply*
But definitely msg_apply_changes() is placed in request_route section. I have just moved code part before calling record_route() function and it helped.
Interesting, but as I remember Kamailio should display in such cases something like below: "...cannot apply msg changes after adding record-route header..."
Thanks for the hint.

Hello,
that's strange, because the condition in the c code is:
if(msg->first_line.type != SIP_REPLY && get_route_type() != REQUEST_ROUTE) { LM_ERR("invalid usage - not in request route or a reply\n"); return -1; }
Which is clear about whether the message is a SIP reply or function is executed in request_route. There is a condition later about the record_route(), but it didn't get to that code...
Maybe you can share the entire request_route you had when the error was exposed.
Cheers, Daniel

Hi Denys,
AFAIK read and writes rtpengine the complete sdp. So manipulating with the "classic" textops tools is more for RtpProxy. You can search for things but writing will done by rtpengine. I remove for example an codec with codec-mask. Or you can manipulate the avp you read from rtpengine (via modparam) in the request.
Did you try to *codec-mask= in the rtpengine calls (answer / manage)? * *So rtpengine takes care for the removal. * *It needs to know what to remove. *

Hey Karsten,
I am not sure RTPengine allows us to delete a specific stream from SDP (as it is the main task I am solving). Anyway, I put route(SDP_VIDEO_REMOVER) above calling record_route and it works well.
So that the main question is about the source of an issue: my configuration or something wrong with sdp_remove_media()?

Hi Denys,
AFAIK read and writes rtpengine the complete sdp. So manipulating with the "classic" textops tools is more for RtpProxy. You can search for things but writing will done by rtpengine. I remove for example an codec with codec-mask. Or you can manipulate the avp you read from rtpengine (via modparam) in the request.
Did you try to *codec-mask= in the rtpengine calls (answer / manage)? * *So rtpengine takes care for the removal. * *It needs to know what to remove. *

If I put route(SDP_VIDEO_REMOVER) into the section route[NATMANAGE] ( https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L820 ), Kamailio shows the error I posted below.
route[SDP_VIDEO_REMOVER] { if ( is_request() && has_body("application/sdp") && sdp_with_media("video") ) { sdp_remove_media("video"); msg_apply_changes(); xlog("L_WARN","[$cfg(route)] *m=video detected* | $rm/$rs/$avp(sdp_mvideo_line)/ \n"); } }

Hello,
that's strange, because the condition in the c code is:
if(msg->first_line.type != SIP_REPLY && get_route_type() !=REQUEST_ROUTE) { LM_ERR("invalid usage - not in request route or a reply\n"); return -1; }
Which is clear about whether the message is a SIP reply or function is executed in request_route. There is a condition later about the record_route(), but it didn't get to that code...
Maybe you can share the entire request_route you had when the error was exposed.

Got message in debug=3: *13(2141) ERROR: textopsx [textopsx.c:181]: ki_msg_apply_changes(): invalid usage - not in request route or a reply*
But definitely msg_apply_changes() is placed in request_route section. I have just moved code part before calling record_route() function and it helped.
Interesting, but as I remember Kamailio should display in such cases something like below: "...cannot apply msg changes after adding record-route header..."
Thanks for the hint.

Hello,
run with debug=3 and what the logs to see if there are error/warning messages.

Hello!
I'm trying to remove m=video stream from incoming SIP/SDP request in th way below:
modparam("rtpengine", "read_sdp_pv", "$avp(read_sdp_pv)") modparam("rtpengine", "write_sdp_pv", "$avp(write_sdp_pv)") ... sdp_remove_media("video"); msg_apply_changes(); sdp_get("$avp(read_sdp_pv)"); xlog("L_WARN","[$cfg(route)] *m=video removed* ci| rb=/$rb/ \n"); xlog("L_WARN","[$cfg(route)] *m=video removed* ci| avp(read_sdp_pv)=/$avp(read_sdp_pv)/ \n"); rtpengine_manage("$avp(rtpengine_offer)"); set_body("$avp(write_sdp_pv)", "application/sdp");
But no luck, xlog shows m=video in $rb and $avp(rtp_sdp_read) as well.
