Hi I still have odd behaviour with the SST module: modparam("sst", "min_se", 300) if (sstCheckMin("1")) { xlog("L_ERR", "$cfg(route) Session Timer too small\n"); exit; } setflag(FLT_DLG); # set the dialog flag setflag(FLT_SST); # Set the sst flag if(is_present_hf("Session-Expires")) { $avp(dlgtimeout) = $(hdr(Session-Expires){s.int}); } On an INVITE containing those header: Session-Expires: 3600;refresher=uac Min-SE: 600 Supported: 100rel,timer Expires: 330 Now Kamailio replies: SIP/2.0 422 Session Timer Too Small Min-SE: 300 What am I doing wrong? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

dlg_onroute(): unable to find dialog for INVITE with route param

by Benoît Panizzon

Happy Eastern Kamailio 5.4 used. On dialogues calls, I noticed this happening on the second re-invite to refresh the session from the B side. dlg_onroute(): unable to find dialog for INVITE with route param 'df9.da75' [2557:22445] and call-id '14148a68-f1b2-485d-b5a2-f9dd7773d2c0' The did df9.da75 is identical to the one in the route-header on the first re-invite from the B side, before this one. No CDR was (yet) generated, and the dialogues is still present and on-going according to the database: CallID [14148a68-f1b2-485d-b5a2-f9dd7773d2c0] H-Entry: 2557 H-ID: 22445 But most probably not in memory as kamcmd dlg.stat_active shows zero (this is on a development node, so no other calls running). There are no sip messages that end the call in between those two re-invites. I see no session timeouts or similar in the logs. Any hint what could cause Kamailio not to find the corresponding dialogue on this re-invite? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Fwd: Kamailio + PostgreSQL

by Stefan

Hi Give it a try without modparams to see if it works, I have the same config but without modparams and it runs without problems. Else have a look into the kamailio logfile for errors. Or check config with "kamailio -c"?

Presence module and privacy

by Ihor Olkhovskyi

Hello! Is there any possibility to control more-or-less privacy related parameters of pua_dialoginfo module (like include_localremote) per subscription? Main idea is I want to show some users full info on the call other user is making, for a different user - just show fact of the call without any details. For now I'm only seeing some manual manipulation over XML based on user who is receiving NOTIFY, but maybe I'm trying to invent a weel here. -- Best regards, Ihor (Igor)

Re: Repository for modules

SCSCF hangs randomly

by solomon.thoobe＠smilecoms.com

Hi All, We currently experience issues where scscf hangs randomly throughout the day. It started hanging once in a month, the issue has gotten worse over time and now it can hang more than 5 times in a day. I have no prior kamailio experience or experience debugging c applications. Kamailio version: 4.4.0 Running ps shows scscf processes are running. Service status also shows scscf is running but it does not respond to sip requests. Testing with sipsack hangs and print timeout errors. root@NGVI-PCSCF2:/var/log # service scscf status * Status of Kamailio SIP Server: * scscf is running sipsak -vv -s sip:NGVI-PCSCF2:6060 received ICMP message received ICMP message** timeout after 500 ms** Below is the extract from log files Apr 5 12:04:46 NGVI-PCSCF2 /usr/sbin/kamailio[5102]: {1 1 ACK isbc505ramjjjr3g23cs02r53cms0uxbg2es(a)10.18.5.64} WARNING: tm [t_lookup.c:1476]: t_unref(): WARNING: script writer didn't release transaction Apr 5 12:04:46 NGVI-PCSCF2 /usr/sbin/kamailio[5104]: {1 3 REGISTER _A9LGREyW2miE7LhPJzv7g..} ERROR: ims_registrar_scscf [save.c:1034]: update_contacts(): Unable to remove contact <sip:+2347020246874@154.66.2.182:5060;rinstance=28bf37d2cce6e4a1;transport=udp> Apr 5 12:04:47 NGVI-PCSCF2 /usr/sbin/kamailio[5131]: ERROR: rr [rr_mod.c:300]: w_record_route(): Double attempt to record-route Apr 5 12:04:47 NGVI-PCSCF2 /usr/sbin/kamailio[5144]: ERROR: rr [rr_mod.c:300]: w_record_route(): Double attempt to record-route Apr 5 12:04:47 NGVI-PCSCF2 /usr/sbin/kamailio[5108]: {1 1 ACK r8ug398d118i8iaaunrouggisntkigkn(a)10.18.5.64} WARNING: tm [t_lookup.c:1476]: t_unref(): WARNING: script writer didn't release transaction Apr 5 12:04:48 NGVI-PCSCF2 /usr/sbin/kamailio[5190]: CRITICAL: <core> [pass_fd.c:275]: receive_fd(): EOF on 23 Apr 5 12:04:48 NGVI-PCSCF2 /usr/sbin/kamailio[5062]: ALERT: <core> [main.c:741]: handle_sigs(): child process 5103 exited by a signal 11 Apr 5 12:04:48 NGVI-PCSCF2 /usr/sbin/kamailio[5062]: ALERT: <core> [main.c:744]: handle_sigs(): core was generated Apr 5 12:06:12 NGVI-PCSCF2 kamailio: WARNING: <core> [daemonize.c:348]: daemonize(): pid file contains old pid, replacing pid Apr 5 12:06:13 NGVI-PCSCF2 /usr/sbin/kamailio[15060]: WARNING: interconnectroute [ported_cache.c:113]: initPortedNumberCount(): Requested records[726049]: Total allocated[871258]: Fat 20% :Total MemUsed [26 MB divided between primary[0x7f22b8667d60] and secondary[0x7f22b93b3390]] pr 5 04:38:24 NGVI-PCSCF2 /usr/sbin/kamailio[14018]: message repeated 107 times: [ ERROR: ims_usrloc_scscf [subscribe.c:430]: free_subscriber(): record not found in hash table] Apr 5 12:50:38 NGVI-PCSCF2 /usr/sbin/kamailio[2604]: WARNING: interconnectroute [icncache_eventprocessor.c:76]: icnRefreshProcess(): total size 2147483648 qm_real_used 700707576 qm_used 387064680 1st_frag 0x7fd5f6d6a690 last_frag 0x7fd676d30fd0 Apr 5 13:00:25 NGVI-PCSCF2 /usr/sbin/kamailio[2437]: ERROR: ims_usrloc_scscf [subscribe.c:430]: free_subscriber(): record not found in hash table Apr 5 13:00:26 NGVI-PCSCF2 /usr/sbin/kamailio[2437]: message repeated 125 times: [ ERROR: ims_usrloc_scscf [subscribe.c:430]: free_subscriber(): record not found in hash table] Apr 5 13:01:25 NGVI-PCSCF2 /usr/sbin/kamailio[2437]: CRITICAL: <core> [main.c:650]: sig_alarm_abort(): shutdown timeout triggered, dying...

urn:emergency:service:sos as RURI

by a.izquierdo＠zaleos.net

Hello, I'm running a Kamailio instance with some routing logic in it. When a UA sends an INVITE with urn:emergency:service:sos as RURI, Kamailio responds with a 400 Bad Request URI. I have set debug log level and it looks like the problem is in the parse_uri.c when sanity_check("1511", "7") is called: parse_uri(): bad char ':' in state 3 parsed: <urn:emergency:service> (21) / <urn:emergency:service:sos> (25) According to RFC8141 (https://www.rfc-editor.org/rfc/rfc8141), this is a correct URN, but maybe I'm missing something. Is there a way to make Kamailio parse this RURI? Kamailio version used: 5.6.4 Thank you!
