Hello, On a Kamailio deployment it seems some users get to a wrong state and permanently keeping in: CS_DIRTY Expires==0 for some long times (even half an hour). When they're in this status seems system cannot reach them. Normally , when working on USRLoc mode 2 if the registration expires usually what I observed is that it just not appears on 'kamctl ul show' The affected users are seen like this: AOR:: blue4 Contact:: sip:Blue4@192.168.101.6:5700 Q= Expires:: deleted Callid:: efc560dc2dbd248d4d1f9d39633773df Cseq:: 49995 User-agent:: PoC-client/OMA1.0 Genaker_X-Platform_IMS_SDK/v2.0 State:: CS_DIRTY Flags:: 0 Cflag:: 0 Socket:: udp:10.133.21.141:6666 Methods:: 8143 The refresh from the clients seem to come intime however some users (and not all) got to this CS_DIRTY state instead of being removed or refreshed. The client refresh looks to arrive in-time so it should be refreshed. Which could be a common cause (misconfiguration?) for this type of problem? If not, could enable debug mode for usrloc or I need to enable for full kamailio? Thanks Albert

Kamailio ignores some ACK
by Efelin Novak 11 May '12

11 May '12

Hi folks, I have a strange problem when Kamailio ignores ACKs in a specific scenario. The call flow is as follows: A -> INVITE -> kamailio -> INVITE -> B [omitting 100 and 180] A <- 200 OK <- kamailio <- 200 OK <- B A -> ACK -> kamailio There are INVITE Xlogs, Reply ROUTE xlogs and media-proxy logs in the syslog. However there is no information about these ACKs. No XLOGs are printed even if there is one on the top of the main route. "tcpdump -A -s0 -i any -n port 5060" receives this message correctly: 14:47:01.246153 IP 111.111.11.11.5060 > 80.80.80.80.60442: SIP, length: 915 SIP/2.0 200 OK Via: SIP/2.0/UDP 111.111.11.11:5060;rport=60442;x-route-tag="tgrp:A";branch=z9hG4bK1634E6A88 Record-Route: <sip:111.111.11.11;lr;ftag=599248D4-260;vsf=AAAAAAAAAAAAAAAAAAAAW0FVT0ZWHF1aNy4xGzA-;nat=yes;did=3bb.327c47e6> Contact: <sip:80.80.80.80:65002;transport=udp> To: "test_account"<sip:bob@server.com>;tag=cb7dd641 From: <sip:alice@111.111.11.50>;tag=599248D4-260 Call-ID: 9AFCFC51.11.50 CSeq: 101 INVITE Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, OPTIONS, INFO, SUBSCRIBE, UPDATE Content-Type: application/sdp Content-Length:263 v=0 o=- 492575093 492575093 IN IP4 111.111.11.60 s=test_device i=(o=IN IP4 192.168.1.10) c=IN IP4 111.111.11.71 t=0 0 m=audio 16416 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:20 14:47:01.254511 IP 111.111.11.50.60442 > 111.111.11.11.5060: SIP, length: 521 ACK sip:80.80.80.80:65002;transport=udp SIP/2.0 Via: SIP/2.0/UDP 111.111.11.50:5060;x-route-tag="tgrp:A";branch=z9hG4bK1634E7DE8 From: <sip:alice@111.111.11.50>;tag=599248D4-260 To: "test_account"<sip:bob@server.com>;tag=cb7dd641 Call-ID: 9AFCFC51.11.50 Route: <sip:111.111.11.11;lr;ftag=599248D4-260;vsf=AAAAAAAAAAAAAAAAAAAAW0FVT0ZWHF1aNy4xGzA-;nat=yes;did=3bb.327c47e6> Max-Forwards: 70 CSeq: 101 ACK Content-Length: 0 My Kamailio version is kamailio 3.1.0 (i386/linux) 1e204f.

error searching pvar "sp."
by Konstantin M. 11 May '12

11 May '12

Hello, When I have the following code: xlog("Dropped INVITE from unregistered location: $si:$sp.\n"); -- I'm getting a parse error: 0(3735) ERROR: <core> [pvapi.c:708]: error searching pvar "sp." 0(3735) ERROR: <core> [pvapi.c:912]: wrong char [./46] in [$sp. ] at [3 (0)] 0(3735) ERROR: xlog [xlog.c:314]: wrong format[Dropped INVITE from unregistered location: $si:$sp. ] When I changed to (removed a point after $sp): xlog("Dropped INVITE from unregistered location: $si:$sp\n"); -- No errors. What I'm doing wrong ? Or it's a parser bug ? Thanks!

t_continue usage
by Vineet Menon 11 May '12

11 May '12

Hi, the module doc page http://www.kamailio.org/docs/modules/3.3.x/modules_k/tmx.html#id2525893says t_continue() has 3rd parameter which says which route block to execute. SO does that mean t_continue() should be present before routing logic(s)?? Where should be t_continue() be placed in a config?? Regards, Vineet Menon

kamailio - mysql master-slave connection question
by Uri Shacked 10 May '12

10 May '12

Hi, In my system configuration, i use 2 DB servers. One will be the master and the other is the slave. In kamailio cfg, I set the mysql server as a host name (not ip). On my DNS server the ip behind the name is the master`s address. I wonder, if I stop the mysqld on the master, and change the ip address in the DNS to the slave`s address. Than i do "kamctl dispatcher reload"... Will kamailio go to the DNS, find the address and connect to the slave? BR, Uri

Re: [SR-Users] Bug: Pua_reginfo
by Gnaneshwar Gatla 10 May '12

10 May '12

Hello, I have noticed that user records were not being correctly saved in the location table. I have tried to fix this will the attached code. This would fix reginfo_handle_notify() to store the user-record in the right format. This fixes part of the problem, I'm still trying to fix the incorrect uri in the PUBLISH message generated by this module. Regards, Gnaneshwar Gatla | InTouch Health | Software Developer 6330 Hollister Ave. Goleta CA, 93117 | P: 805.562.8686 ext: 199 From: Gnaneshwar Gatla Sent: Tuesday, May 08, 2012 4:58 PM To: SIP Router - Kamailio (OpenSER) and SIP Express Router (SER) - Users Mailing List Cc: Carsten Bock (carsten(a)ng-voice.com) Subject: Bug: Pua_reginfo Hello all, There seems to be an deadlock between registrar and pua_reginfo module whenever a SIP client refreshes its registration. 1. The pua_reginfo does not publish Event:reg when a sip client registers for the first time. 2. The pua_reginfo module does not use ul.lock_udomain() to lock the ul table to get the record. 3. The pua_reginfo does not release the record that it accessed from ul.get_urecord() Since the record is not released, when the client re-registers, the registrar module is unable to query for the userlocation and sends a 200 OK response with 0 bindings. Which leads to no contact header in the response message and eventually deletion of the record in the location table(expires). I have tried to fix this using lock_udomain, release_urecord and unlock_udomain, but failed to rectify the error. The deadlock happens in modules_k/usrloc/udomain.c (db_load_urecord()). if (ul_dbf.query(_c, keys, 0, vals, columns, (use_domain)?2:1, 13, order, &res) < 0) My Question: 1. is pua_reginfo supposed to delete record from location database and send the same data to a presence server? a. If above is true, then should the registrar module insert a new record in the location table? b. If above is false, the registrar module should be able to refresh/update the record in the location table. This error is also impacts pua_usrloc module too as it cannot access the record and sends creates an incorrect uri. Help: I'm new and learning how Kamailio works, is there a clean way that pua_reginfo module gets the record?

Problem with radius_www_authorize
by Ricardo Martinez 09 May '12

09 May '12

Hello. We have detected a behavior not specified in the docs. I ask for support to solve this issue. We are using a Radius system to authorize our clients, so, for REGISTER we use the command radius_www_authorize(“mydomain.com”) According to the documentation the possible answers are : Negative result codes may be interpreted as follows: -7 (internal error) - some internal error occurred (see syslog); -6 (nonce reused) - nonce is used more than once; -5 (no credentials) - credentials were not found in request; -4 (stale nonce) - stale nonce; -3 (authorization failed) - RADIUS responded with Access Reject which may be, for example, due to user not found or wrong password; -1 (error) - some error occured during authorization (see syslog); Despite of this, for BadPassword or UserNotExist from the radius answer the radius_www_authorize command return “-2” as a retcode. So, is the documentation missing something? Or I’m doing something wrong? Thanks Ricardo Martinez.-
