[kamailio/kamailio] Possibly adjusting the SDP parser to be more lenient towards scenarios where a stream is being removed/rejected and connection-information "c=" is only available per media (no session-wide "c=") and the removed/rejected stream omits all fields (Issue #3982)

### Description I encountered an issue with a specific device that is receiving a T.38 fax. The call gets established towards the device normally with inband media, then the device requests T.38 media and tries to remove the audio media via sending port 0 in the ReInvite SDP. Also it sends connection-information only on the media level and there is no "c=" on the session level. Reading through the related RFCs and the kamailio code and discussing this on the mailing list, we came to the conclusion that kamailio is doing everything correct as per RFC. Though we were wondering if it would be possible to adjust the parser to be not as strict as it is right now, and allow a missing "c=" line on the media-level if the stream is removed/rejected via port 0, since i see no sense in requiring connection information. Of course we are also in contact with the vendor to hopefully adjust on their side. Here are the related RFCs: 1. RFC8866 5.7 `A session description MUST contain either at least one "c=" line in each media description or a single "c=" line at the session level. It MAY contain a single session-level "c=" line and additional media-level "c=" line(s) per-media-description, in which case the media-level values override the session-level settings for the respective media.` 2. RFC3264 8.2 `Existing media streams are removed by creating a new SDP with the port number for that stream set to zero. The stream description MAY omit all attributes present previously, and MAY list just a single media format.` At first i was especially confused by the RFC3264 8.2 part, since it seemed correct what the device is sending, but if you read carefully and keep the wording for SDP in mind only attributes ("a=") MAY be omitted. So a "c=" line should still be in the SDP for the removed media if it's not included on the session-level. Or do you see this differently? ### Expected behavior Kamailio allows and parses the SDP when there is no session-wide "c=", a media stream is being removed via port zero and there is no "c=" for this media stream and only the remaining media streams include a "c=" line. #### Actual observed behavior Kamailio throws an error when trying to parse the SDP. #### Log Messages ``` <core> [core/parser/sdp/sdp.c:523]: parse_sdp_session(): can't find media IP in the message ``` #### SIP Traffic ``` v=0 o=xmserver 1726638425 1726638427 IN IP4 169.254.1.1 s=xmserver t=0 0 m=audio 0 RTP/AVP 8 m=image 56002 udptl t38 c=IN IP4 169.254.1.1 a=sendrecv a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval:0 a=T38FaxTranscodingMMR:0 a=T38FaxTranscodingJBIG:0 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:200 a=T38FaxMaxDatagram:72 a=T38FaxUdpEC:t38UDPRedundancy ``` ### Possible Solutions ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.3 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 12.2.0 ``` * **Operating System**: ``` Debian 12 Linux hostname 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3982 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Inactive video stream: can't find media IP in the message (Issue #3406)
by schoberw 31 May '25

31 May '25

### Description In some situations the other side UA must reply with an inactive media stream. E.g. if video was added but not supported by the other side. The UAS then must answer with an m=video 0 RTP/.. line. It seams that the video section must contain a c= line with an IP address for rtpengine to function. If there is no c line (no IP address) the SDP body cannot be parsed and thus no RTP proxy is invoked. ### Troubleshooting Not easy to reproduce since the answer must bei "wrong". Is it correct to reply an SDP body (media = video) like this? ``` m=video 0 RTP/AVPF 96 a=label:1 a=inactive a=mid:1 ``` Maybe not (but Audiocodes SBC lates LTS version does it) - so we are dependent on other side now that this service works. #### Reproduction reInvite with Video to a UA that has no video Support (e.g. Bria -> Snom). Drop the c line in the video part with some textops in 200 OK (just to reproduce of course). A -> B, connect the call A -> + video, B has no video support A presses hold #### Log Messages Incoming 200 OK after doing hold with an inactive video: ``` v=0 o=root 436040161 309284577 IN IP4 1.2.3.5 s=call t=0 0 m=audio 14200 RTP/AVPF 9 8 126 c=IN IP4 1.2.3.5 a=ptime:20 a=recvonly a=mid:0 a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:126 telephone-event/8000 a=fmtp:126 0-15 m=video 0 RTP/AVPF 96 a=label:1 a=inactive a=mid:1 Mar 27 17:52:22 c5p05es2-1 /usr/sbin/kamailio[2938205]: ERROR: <core> [core/parser/sdp/sdp.c:490]: parse_sdp_session(): can't find media IP in the message Mar 27 17:52:22 c5p05es2-1 /usr/sbin/kamailio[2938205]: INFO: <script>: >>> Sending Reply: 200 OK (1.2.3.4:443 -> 100.108.48.38:65251) ``` Compare to working SDP parsing: ``` a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:126 telephone-event/8000 a=fmtp:126 0-15 m=video 0 RTP/AVP 96 c=IN IP4 1.2.3.5 a=inactive a=mid:1 Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: ONREPLY_ROUTE[FORWARD] Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: ROUTE[RTPP_REPLY] Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: > 200 with video Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: > 200 with inactive video Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: > Remove inactive video Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: > Answer to WebRTC client: 200 - qijpuibkv6ufhnd282ks Mar 27 18:00:17 c5p05es2-1 /usr/sbin/kamailio[2942881]: INFO: <script>: >>> Sending Reply: 200 OK (91.237.65.14:443 -> 80.108.48.38:65388) ``` ### Possible Solutions Tried to fix in script: ``` if(sdp_with_media("video")) xlog("L_INFO", "> $rs with video"); if(sdp_with_active_media("video")) xlog("L_INFO", "> $rs with active video"); if(!sdp_with_active_media("video")) xlog("L_INFO", "> $rs with inactive video"); if(sdp_with_media("video") && !sdp_with_active_media("video")) { # try fix for RMT#60189 xlog("L_INFO", "> Remove inactive video"); sdp_remove_media("video"); msg_apply_changes(); # needed? } ``` But since sdpops cannot parse it cannot remove the buggy media, too. See the log: non of the xlog is logging. If there is inactive media the c line is not mandatory. The parser should accept this by adding a default IP of 0.0.0.0, if needed Doing tricks with textops is not a easy nor performant solution to accept this wrong SDP from other parties. ### Additional Information ``` version: kamailio 5.6.4 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 10.2.1 ``` * **Operating System**: Debian Bullseye -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3406 You are receiving this because you are subscribed to this thread.

It adds a new parameter `enable_shared_ctx` in `tls` module that if set to 0, preserves the old behavior and if set to 1 (other than 0 tbh), it creates a single SSL context that is being shared. This have the effect of using way less memory when initialized as well, but also minimizes (can't say it fixes the problem) the `tls.reload` memory increase. I have also added a small markdown (comparison.md) file, where some comparisons where made between enabled/disabled shared context and with/without CA file (where the initial problem was occurring by the reporter). Feedback would be necessary to verify whether this patch, acts as expected and kamailio works as intented.

QuincyGao created an issue (kamailio/kamailio#4190)  ### Description  I want to use opensips as SBC, When the agent registers to kamailio, the contact content is modified to the ip and port of kamailio, and then Register is forwarded to the agent. remove_hf("Contact") can't remove the whole Contact( field, vlue). here is my config: ``` route[REGISTRAR] { if (!is_method("REGISTER")) return; if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); #!ifdef WITH_NATSIPPING # do SIP NAT pinging setbflag(FLB_NATSIPPING); #!endif } fix_nated_contact(); if (!save("location","0x02")) { #if (!save("location")) { sl_reply_error(); } $fs="udp:172.16.4.111:5461"; $du="sip:172.16.4.114:5060"; remove_hf("Contact"); $var(contact) = "Contact: <sip:" +$fU+"@"+"172.16.4.111:5461>;expires=120\r\n" ; append_hf("$var(contact)"); route(RELAY); exit; } ``` here is the sip message: ``` 2025/03/26 16:36:07.706093 172.16.4.111:5461 -> 172.16.4.114:5060 REGISTER sip:172.16.4.111:5460 SIP/2.0 Via: SIP/2.0/UDP 172.16.4.111:5461;branch=z9hG4bKfc7e.d2df36f3b5681afeb71e442e645de38d.0 Via: SIP/2.0/UDP 172.16.80.3:49309;received=172.16.80.3;rport=49309;branch=z9hG4bKPj8ab8bd1d3c3a4c1bb0cd639540fa3183 Max-Forwards: 69 From: <sip:1008@172.16.4.111>;tag=95f7f5601f8b40458a1efe6923ab0a29 To: <sip:1008@172.16.4.111> Call-ID: f84b643f5d284d18a0d8175e1ef4d747 CSeq: 33264 REGISTER User-Agent: MicroSIP/3.21.6 sip:1008@172.16.80.3:49309;obExpires: 120 Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Content-Length: 0 Contact: <sip:1008@172.16.4.111:5461>;expires=120 ``` you can see the problem is that: `sip:1008@172.16.80.3:49309;obExpires: 120` , `sip:1008@172.16.80.3:49309` is the value of the Contact field after fix_nated_contact(). ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.5 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: compiled on 11:27:01 Mar 21 2025 with gcc 4.8.5 ``` * **Operating System**:  ``` Centos7.9 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4190 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] siptrace: sip_trace_mode("d") not working (Issue #4178)
by c.long 22 May '25

22 May '25

longchun4835 created an issue (kamailio/kamailio#4178)  ### Description Using function sip_trace_mode() with parameter d to enable dialog tracing mode logs: ``` BUG: siptrace [siptrace.c:1671]: add_info_xavp(): URI should be in raw format here ERROR: siptrace [siptrace.c:888]: sip_trace_helper(): failed to serialize siptrace info! Won't trace dialog! ``` ### Troubleshooting #### Reproduction my module parameters: ``` #!ifdef WITH_HOMER loadmodule "siptrace.so" modparam("siptrace", "duplicate_uri", HOMER_URL) modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", HOMER_HEP_ID) #!endif ... request_route { ... if (is_method("INVITE")) { sip_trace_mode("d"); } } ``` ### Possible Solutions I checked the source code and found that the issue occurs when sip_trace_helper() is called inside the ki_sip_trace_mode() function, with the third parameter (duri) set to NULL. I don’t quite understand the logic behind passing NULL does this mean that the 'D' parameter will never working when calling sip_trace_mode()? Additionally, I have another question: in the sip_trace_helper() function, why does it call trace_transaction() instead of trace_dialog() when strace_type == SIPTRACE_DIALOG? ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.4 (x86_64/linux) a004cf flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a004cf compiled on 09:14:30 Jan 23 2025 with gcc 8.3.1 ``` * **Operating System**: ``` NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4178 You are receiving this because you are subscribed to this thread.
