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. -- BR, Denys Pozniak _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users

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"); } } 16(15993) DEBUG: sdpops [sdpops_mod.c:883]: sdp_with_media(): attempting to search for media type: [video] 16(15993) DEBUG: sdpops [sdpops_mod.c:898]: sdp_with_media(): stream 0 of 0 - media [audio] 16(15993) DEBUG: sdpops [sdpops_mod.c:898]: sdp_with_media(): stream 1 of 0 - media [video] 16(15993) DEBUG: sdpops [sdpops_mod.c:1038]: sdp_remove_media(): attempting to search for media type: [video] 16(15993) DEBUG: sdpops [sdpops_mod.c:1055]: sdp_remove_media(): stream 0 of 0 - media [audio] 16(15993) DEBUG: sdpops [sdpops_mod.c:1055]: sdp_remove_media(): stream 1 of 0 - media [video] 16(15993) DEBUG: sdpops [sdpops_mod.c:1061]: sdp_remove_media(): removing media stream: video16(15993) *ERROR: textopsx [textopsx.c:181]: ki_msg_apply_changes(): invalid usage - not in request route or a reply* 16(15993) WARNING: <script>: [SDP_VIDEO_REMOVER] *m=video detected* | INVITE/<null>/m=video 0 RTP/AVP 97 99 98 110 / 16(15993) DEBUG: sdpops [sdpops_mod.c:1133]: sdp_with_transport(): attempting to search for transport type: [RTP/SAVP] 16(15993) DEBUG: sdpops [sdpops_mod.c:1148]: sdp_with_transport(): stream 0 of 0 - transport [RTP/AVP] 16(15993) DEBUG: sdpops [sdpops_mod.c:1148]: sdp_with_transport(): stream 1 of 0 - transport [RTP/AVP] 16(15993) DEBUG: sdpops [sdpops_data.c:222]: sdpops_build_ids_list(): codecs list [PCMA] - at name [PCMA] with list ids [8] 16(15993) DEBUG: sdpops [sdpops_data.c:255]: sdpops_build_ids_list(): codecs list [PCMA] - ids list [8] 16(15993) DEBUG: sdpops [sdpops_mod.c:1433]: sdp_with_codecs_by_id(): attempting to search codecs in sdp: [8] 16(15993) DEBUG: sdpops [sdpops_mod.c:1448]: sdp_with_codecs_by_id(): stream 0 of 0 - payloads [121 122 123 124 9 0 8 18 101] 16(15993) DEBUG: sdpops [sdpops_mod.c:1465]: sdp_with_codecs_by_id(): codecs [121 122 123 124 9 0 8 18 101] - found [8] 16(15993) DEBUG: sdpops [sdpops_mod.c:1448]: sdp_with_codecs_by_id(): stream 1 of 0 - payloads [97 99 98 110] 16(15993) DEBUG: sdpops [sdpops_mod.c:1460]: sdp_with_codecs_by_id(): codecs [97 99 98 110] - not found [8] 16(15993) DEBUG: sdpops [sdpops_data.c:222]: sdpops_build_ids_list(): codecs list [PCMU] - at name [PCMU] with list ids [0] 16(15993) DEBUG: sdpops [sdpops_data.c:255]: sdpops_build_ids_list(): codecs list [PCMU] - ids list [0] 16(15993) DEBUG: sdpops [sdpops_mod.c:1433]: sdp_with_codecs_by_id(): attempting to search codecs in sdp: [0] 16(15993) DEBUG: sdpops [sdpops_mod.c:1448]: sdp_with_codecs_by_id(): stream 0 of 0 - payloads [121 122 123 124 9 0 8 18 101] 16(15993) DEBUG: sdpops [sdpops_mod.c:1465]: sdp_with_codecs_by_id(): codecs [121 122 123 124 9 0 8 18 101] - found [0] 16(15993) DEBUG: sdpops [sdpops_mod.c:1448]: sdp_with_codecs_by_id(): stream 1 of 0 - payloads [97 99 98 110] 16(15993) DEBUG: sdpops [sdpops_mod.c:1460]: sdp_with_codecs_by_id(): codecs [97 99 98 110] - not found [0] пт, 1 нояб. 2019 г. в 14:38, Daniel-Constantin Mierla &lt;miconda(a)gmail.com > 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.
