[kamailio/kamailio] rms_bridge() doesn't send out B-leg: run_onsend(): required parameters are not available - ignoring (#2524)
by Anthony Messina 26 Oct '20

26 Oct '20

### Description  Testing out rtp_media_server module's `rms_bridge()` function with the intention of bridging A-leg to B-leg (an Asterisk conference server). The B-leg never gets sent out and after the call times out, this testing instance crashes. Config slightly modified from https://github.com/kamailio/kamailio/blob/master/src/modules/rtp_media_serv… ``` ... loadmodule "uac.so" event_route[rms:bridged] { xnotice("[rms:bridged] ...\n"); } route { if (t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); if (is_method("REGISTER")) { save("location"); exit; } xnotice("[$rm][$ci]\n"); if (is_method("INVITE") && !has_totag()) { fix_nated_contact(); if ($rU == "888") { $var(target) = "sip:conference@example.com:5080;"; if (!rms_bridge("$var(target)", "rms:bridged")) { send_reply("503", "server error"); xerr("rtp_media_server bridge error!\n"); } exit; } if (!rms_answer("rms:answered")) { t_reply("503", "server error"); xerr("rtp_media_server error!\n"); exit; } } if(rms_dialog_check()) rms_sip_request(); exit; } ``` ### Troubleshooting I added `loadmodule "uac.so"`, though I'm not sure it's required. #### Reproduction  #### Debugging Data  I can only do a stack trace at the moment running this test in a systemd-nspawn container ``` Stack trace of thread 589: #0 0x00007fb449848518 n/a (/usr/lib64/kamailio/modules/rtp_media_server.so + 0x2f518) #1 0x00007fb44982682b n/a (/usr/lib64/kamailio/modules/rtp_media_server.so + 0xd82b) #2 0x00000000005cca6b n/a (/usr/sbin/kamailio + 0x1cca6b) #3 0x000000000041cf90 n/a (/usr/sbin/kamailio + 0x1cf90) #4 0x000000000041e9ea n/a (/usr/sbin/kamailio + 0x1e9ea) #5 0x0000000000421c65 n/a (/usr/sbin/kamailio + 0x21c65) #6 0x000000000042c61c n/a (/usr/sbin/kamailio + 0x2c61c) #7 0x0000000000434cbd n/a (/usr/sbin/kamailio + 0x34cbd) #8 0x00007fb44a8b0042 __libc_start_main (libc.so.6 + 0x27042) #9 0x000000000041bbde n/a (/usr/sbin/kamailio + 0x1bbde) ``` #### Log Messages  ``` kamailio[275]: 10(275) INFO: rtp_media_server [rtp_media_server.c:254]: rms_dialog_action_check(): dialog action RMS_BRIDGING [0_3746724993@2001:db8::99] kamailio[275]: 10(275) INFO: rtp_media_server [rtp_media_server.c:583]: rms_bridging_call(): parsed[sip:conference@example.com:5080][0] kamailio[275]: 10(275) INFO: rtp_media_server [rtp_media_server.c:599]: rms_bridging_call(): si[0x7f83fddb78e0]call-id[0_3746724993@2001:db8::99]cseq[0]ruri[32|sip:conference@example.com:5080]remote_uri[<sip:conference@example.com:5080>]local_uri[<sip:888@example.com>] kamailio[275]: 10(275) DEBUG: tm [uac.c:450]: t_uac_prepare(): next_hop=<sip:conference@example.com:508> kamailio[275]: 10(275) DEBUG: <core> [core/dns_cache.c:527]: _dns_hash_find(): (example.com(12), 1), h=205 kamailio[275]: 10(275) DEBUG: <core> [core/resolve.c:985]: get_record(): skipping 2 NS (p=0x9a0e6e, end=0x9a0ef2) kamailio[275]: 10(275) DEBUG: <core> [core/resolve.c:998]: get_record(): parsing 4 ARs (p=0x9a0e9a, end=0x9a0ef2) kamailio[275]: 10(275) DEBUG: <core> [core/dns_cache.c:1633]: dns_get_related(): (0x7f83fddbb878 (example.com, 1), 1, *0x7f8406d319f0) (0) kamailio[275]: 10(275) DEBUG: <core> [core/dns_cache.c:739]: dns_cache_add_unsafe(): adding example.com(12) 1 (flags=0) at 205 kamailio[275]: 10(275) DEBUG: tm [uac.c:158]: dlg2hash(): hashid 35754 kamailio[275]: 10(275) DEBUG: tm [uac.c:678]: send_prepared_request_impl(): uac: 0x7f83fddb9a10 branch: 0 to 10.77.79.3:508 kamailio[275]: 10(275) DEBUG: <core> [core/onsend.c:50]: run_onsend(): required parameters are not available - ignoring kamailio[275]: 10(275) ERROR: rtp_media_server [rtp_media_server.c:622]: rms_bridging_call(): tmb.t_request_within ok ``` #### SIP Traffic  There is no SIP traffic generated to `<sip:conference@example.com:5080>` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.4.1-8.gitd43872c11e.fc32.1 (x86_64/linux) 09fd6a 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_BLACKLIST, 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: 09fd6a compiled on 00:00:00 Oct 21 2020 with gcc 10.2.1 ``` * **Operating System**:  ``` Linux kamtest 5.8.16-200.fc32.x86_64 #1 SMP Mon Oct 19 14:17:16 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
