usrloc db_mode 2 and dropped contacts
by Alex Balashov 09 Mar '20

09 Mar '20

Hi, On 4.4.7, since switching to db_mode 2 for usrloc with the following settings: modparam("usrloc", "db_mode", 2) modparam("usrloc", "timer_procs", 2) modparam("usrloc", "skip_remote_socket", 1) modparam("usrloc", "timer_interval", 30) modparam("usrloc", "matching_mode", 0) I seem to run into a situation where, despite starting from zero local registrations and an empty DB `location` table, out of ~1700 registrations visible in the runtime usrloc table, about 60-80 never make it into the database. This is because they're being continuously UPDATE'd rather than INSERT'd, so there is some presumption that they should already be in the Postgres database. But they're not. This gap seems to very slowly grow over time. I understand that this option is intended to deal with a scenario like that: https://kamailio.org/docs/modules/5.3.x/modules/usrloc.html#usrloc.p.db_che… but the documentation doesn't say it needs to be on for db_mode 2 to work correctly, and it's off by default. I'm wondering what causes certain registrants to get into this state in the first place, where the registrar presumes that they've already been synced to the DB and only need to be update'd on renewal, where in fact they have not been synced. Causes I've ruled out: 1) The contacts being ignored due to non-local socket or other invalidation; 2) Contacts being explicitly deleted by an outside process. Any ideas appreciated! -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

problem in sending out calls
by Mohammad Reza Keshavarzianpoor 06 Mar '20

06 Mar '20

Hi, I installed kamailio and siremis. I receive incoming calls from gateway and all is ok. but about sending out calls using dynamic routes I have problem, always I get "not found" error on calling out phone numbers. 1.I need to send my did number with call to approved by gateway 2.do drouting module needs to enabled by config file? 3. if any better solution than drouting, write please, all I need is every subscriber have its did number and route on outgoing calls too. Thanks

rtpengine failover in same SIP dialog with response Unknown call-ide
by Michal Popovic 06 Mar '20

06 Mar '20

Hi, we are facing the issue with automated failover in same SIP dialog in rtpengine module. This issue occurs after we upgraded version 4.4.7 to 5.3.2 and only for rtpengines that are in another datacenter with latency higher than about 100ms. configuration modparam("rtpengine", "rtpengine_sock", "1 == udp:10.0.0.1:2222 udp:10.0.0.2:2222") modparam("rtpengine", "rtpengine_sock", "1 == udp:10.0.0.3:2222 udp:10.0.0.4:2222") INVITE request from kamailio to 10.0.0.1:2222 3:ICE6:remove5:flagsl13:trust-address16:always-transcode17:asymmetric-codecs12:loop-protecte7:replacel6:origin18:session-connectione18:transport-protocol7:RTP/AVP8:rtcp-muxl5:demuxe7:call-id20:xxx:received-froml3:IP414:x.x.x.xe8:from-tag10:naluniuntp7:command5:offere RESPONSE 6:result2:oke ANSWER request is than send to 10.0.0.2:2222 with error 3:ICE5:force5:flagsl13:trust-address16:always-transcode17:asymmetric-codecs12:loop-protecte7:replacel6:origin18:session-connectione18:transport-protocol9:RTP/SAVPF8:rtcp-muxl6:accept5:offere7:call-id20:l63nam58lomphlpvli9o13:received-froml3:IP414:18.212.137.170e8:from-tag10:naluniuntp6:to-tag10:as297c65177:command6:answere RESPONSE d6:result5:error12:error-reason15:Unknown call-ide Only possible fix is to have only one setid with only one server.

uac_replace_from in 200 OK of BYE
by Grant Bagdasarian 06 Mar '20

06 Mar '20

Hello, We've been using the uac_replace_from function to anonymize the From header to anonymous(a)anonymous.invalid<mailto:anonymous@anonymous.invalid>. The uac module makes use of the dialog module for restoring the original URI. Everything works fine, except when the callee sends the BYE request (replaced uri is present in To header): the 200 OK received by the callee of the BYE suddenly contains the original URI in the To header. We're running Kamailio 5.1. Is this a known bug or limitation of the uac module? Any way to have this replaced correctly (preferably automatically by uac module)? Regards, Grant

sip domain
by Joli Martinez 05 Mar '20

05 Mar '20

Hello, We have several SIP domains coming into our SBC. I need to build a Kamailio box that will 302 the call to the appropriate server based on the domain. If the call does not come in with a recognized domain I would like for it to 404 the call. Not sure how to do this. Can someone point me in the right direction?

Unexpected behavior on tmrec with monthly recurrence
by David Gonçalves 04 Mar '20

04 Mar '20

Hi, During some tests with the module tmrec, we stumble upon an unexpected behavior of the monthly recurrence with days of the week. The last week does not match our expected date. For example, the last Monday of March 2020 is day 30 (fifth Monday of the month) however, neither the 5MO or -1MO configuration on the bday parameter match with a timestamp configured to day 30. The same situation is verified on months with only 4 weeks. To easily explain the behavior we create this configuration: $var(ts)="1584355625"; # Monday, March 16, 2020 10:47:05 if(tmrec_match("20200101T090000|PT8H|monthly||1|3MO||||","$(var(ts){s.int})")) { xlog("L_INFO","Epoch $var(ts) matches with 3MO\n"); }else{ xlog("L_INFO","Epoch $var(ts) doesn't match with 3MO\n"); } $var(ts)="1584960425"; # Monday, March 23, 2020 10:47:05 if(tmrec_match("20200101T090000|PT8H|monthly||1|4MO||||","$(var(ts){s.int})")) { xlog("L_INFO","Epoch $var(ts) matches with 4MO\n"); }else{ xlog("L_INFO","Epoch $var(ts) doesn't match with 4MO\n"); } $var(ts)="1585565225"; # Monday, March 30, 2020 10:47:05 if(tmrec_match("20200101T090000|PT8H|monthly||1|5MO||||","$(var(ts){s.int })")){ xlog("L_INFO","Epoch $var(ts) matches with 5MO\n"); }else{ xlog("L_INFO","Epoch $var(ts) doesn't match with 5MO\n"); } $var(ts)="1584960425"; # Monday, March 23, 2020 10:47:05 if(tmrec_match("20200101T090000|PT8H|monthly||1|-1MO||||","$(var(ts){s.int })")){ xlog("L_INFO","Epoch $var(ts) matches with -1MO\n"); }else{ xlog("L_INFO","Epoch $var(ts) doesn't match with -1MO\n"); } The results were: Epoch 1584355625 matches with 3MO Epoch 1584960425 matches with 4MO Epoch 1585565225 doesn't match with 5MO Epoch 1584960425 matches with -1MO Are we configuring the tmrec_match wrongly? -- Cumprimentos / Best regards, *David Gonçalves* Research and Development Technician Phone: +351 256 370 980 Email: david.goncalves(a)itcenter.com.pt

Help me open ports for my kamailio
by Stefan Troplev 04 Mar '20

04 Mar '20

Hi, I've been struggling around with my kamailio configuration. I've managed to install kamailio on Ubuntu Server and configured 2 clients, I've registered them in Zoiper to my server. They can call each other, but are unable to talk. There is no audio heard. Ports opened on the router are 20000-30000 UDP and both TCP and UDP for 5060 and 5062. Are these ports correctly opened?
