[Kamailio-Users] tm retransmits and times out even though reponse is received

by Alex Hermann

Hello, I'm seeing an increasing amount of spurious timeouts on my proxies. Even though the proxy receives a "100 Trying" response immediately after relaying the request, tm will send retransmits and times out eventually. Below is a commented log snippet. The timeout occurs on the proxy named 'balancer1'. Both are on the same host. I verified that the 100 Trying response is received in a t_on_reply block, so it is recognized by tm as belonging to a transaction. When needed, I'll provide a debug log when it occurs again. Meanwhile, any idea what is causing this? This is on kamailio 1.5+svn5768 fr_timer = 10 fr_timer_avp = 2 # Initial request received on balancer May 15 12:32:01 balancer1[24170]: [2 INVITE] - New request. <sip:uac@domain> => <sip:uas@domain> May 15 12:32:01 balancer1[24170]: [2 INVITE] Relaying # Initial request received on proxy May 15 12:32:01 proxy1[23803]: [2 INVITE] - New request. <sip:uac@domain> => <sip:uas@domain> # Balancer receives 100 response May 15 12:32:01 balancer1[24166]: [2 INVITE] - Reply. 100 Trying # Proxy relays request May 15 12:32:01 proxy1[23803]: [2 INVITE] Relaying # Proxy receives retransmission from balancer ???

[Kamailio-Users] ERROR:mi_fifo:mi_fifo_server: fifo command must begin with :: early_dialogs (1.5 rev 5834)

by Iñaki Baz Castillo

Hi, I use the Munin plugin I did in various servers running Kamailio 1.5 (Debian 64 bits). The munin plugins performs the Mi command: kamctl fifo get_statistics inuse_transactions In one of them the installed revision is 5834 and the plugin works perfectly, no errors in 3 months with high traffic. However in the other server (revision 5925) there are no traffic yet but the plugin fails sometimes (maybe once each 2-3 days). Sometimes it gets an error: ERROR:mi_fifo:mi_fifo_server: fifo command must begin with :: early_dialogs and sometimes it gets wrong value: kamctl fifo get_statistics inuse_transactions => 2819624 (with no traffic !!!) In the second case the Munin grapsh gets corrupted due to so high value. Could it be a bug in dialog module?

[Kamailio-Users] uac_replace_from check

by jh＠tutpro.com

if i have understood correctly, if uac_replace_from() is called in "auto" mode, encoded from uri is added into an extra param of r-r header when the request is forwarded towards uas. does the module check that reply to the request from uas really includes the added parameter in its r-r header or is correct operation of in-dialog requests at the mercy of the uas? -- juha

Re: [Kamailio-Users] LCR problem with "id" column and match priorities

by jh＠tutpro.com

it turned out that the problems ricardo reported on gw selection in lcr module were due to the fact that he has the same gw (same in terms of ip address) in more than one gw group and in each group the gw has different trip/tag attributes. load_gws() function tries the same gateway only once, but it is not currently well defined from which group gw's attributes are taken when request is sent to the gateway. currently the attributes are taken from the gw group, which happens to be the first in in-memory gw table. one could think that this is a feature, i.e., if the same gw is in many gw groups, it must have the same attributes in every group. the other alternative is that this is a bug, i.e., same gw's attributes can differ from group to group and the ones that are used must be the ones of the chosen group. i have a fix written for sr_3.0 lcr module, but i'm hesitating to introduce the fix also to version 1.5, because the fix has not been tested well yet. any opinions on what should be done? -- juha

[Kamailio-Users] Broken Debian packaging in Kamailio 3.0.0-RC

by Kim Philby

Hi! I've tried to make Debian packages for latest Kamailio, but some issues arised. First, packages are named ser-stuff, shouldn't they be called kamailio-stuff even though Kamailio now uses SIP-Router core? Also, Debian package making seems to be broken: # install the *.sql files for ser_mysql.sh script cp -f scripts/mysql/*.sql /home/kmphlb/src/kamailio-3.0.0/kamailio/debian/ser/usr/lib/ser/ cp: target «/home/kmphlb/src/kamailio-3.0.0/kamailio/debian/ser/usr/lib/ser/» is not a directory make[1]: *** [install] Error 1 Directories are named 'ser'. Shouldn't it be just 'kamailio'? Regards, -- Kim Philby

[Kamailio-Users] Kamailio 3.0.0 RC1

by Daniel-Constantin Mierla

Hello, I created a tarball with sources of Kamailio 3.0.0 RC1 in order to easy the usage and testing: http://www.kamailio.org/pub/kamailio/3.0.0-rc1/src/kamailio-3.0.0-rc1_src.t… There is also now a tutorial to guide the installation of kamailio 3.0 branch from GIT repository: http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.0.x-from-git Two wiki pages were created to collect what is new in Kamailio 3.0 and how to migrate to this version: http://www.kamailio.org/dokuwiki/doku.php/features:new-in-3.0.x http://www.kamailio.org/dokuwiki/doku.php/install:1.5.x-to-3.0.0 Both documents need a lot of care since many new features are missing or are not detailed, and definitely update guidelines do not cover all changes. Help is very much appreciated there. As we keep hunting and fixing issues, improve documentation, I hope to get to full release Kamailio 3.0.0 very soon. Enjoy RC1 meanwhile and report any issue you find to sr-dev(a)lists.sip-router.org. Thanks, Daniel

[Kamailio-Users] Route header problem

by Alex Rendour

Hello, We have a problem with route on header. I receive an ack from X.X.X.X (asterisk) on Y.Y.Y.Y (kamailio 1.5.3). Y.Y.Y.Y relay ACK to Z.Z.Z.Z Y.Y.Y.Y this route from X.X.X.X: <sip:Y.Y.Y.Y;lr=on;ftag=as7e58db45>,<sip:11dc0d7918b56374@Z.Z.Z.Z;lr> And forward as the same to Z.Z.Z.Z. The route header must be : <sip:11dc0d7918b56374@Z.Z.Z.Z;lr> I think my kamailio must delete the first part of the route header, like this explaination: http://www.tech-invite.com/Ti-sip-dialog.html#inv-ack Could you help me?

[Kamailio-Users] kam 1.5 syslog on solaris 10

by Robert McGilvray

I'm having some issues getting kam to log correctly to syslog after it daemonizes. I get all the initialization entries in the proper logfile but nothing after that - I have xlog statements throughout the config which only show up in syslog if fork=no. I've tested my syslog config with the system logger which works correctly executed as the kamailio user. If I run syslog in debug I don't see it receiving anything from kam after initialization. Any ideas? log_stderror=no log_facility=LOG_LOCAL1 debug=7 fork=yes children=4 /etc/syslog.conf (with tabs) local1.debug /var/log/globeop/kamailio.log This is the correct format of syslog in solaris. It only uses wildcard (*) in facility not levels. Specifying debug will include everything at higher levels. From the man page: For a given facility and level, syslogd matches all messages for that level and all higher levels. For example, an entry that specifies a level of crit also logs messages at the alert and emerg levels. This config is working correctly on sol 10 with openser 1.3. ykt1sipprd2# tail -f /var/log/globeop/kamailio.log Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 951507 local1.debug] DBG:core:grep_aliases: comparing host [2:loghost:5060] with us [1:loghost:5060] Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 951507 local1.debug] DBG:core:grep_aliases: comparing host [2:loghost:5060] with us [1:ykt1sipprd2:5060] Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 793175 local1.debug] DBG:core:grep_aliases: no match for: [2:loghost:5060] Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 634971 local1.debug] DBG:core:socket2str: <tcp:172.20.151.148:5060> Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 797031 local1.debug] DBG:core:fm_malloc_init: F_OPTIMIZE=16384, /ROUNDTO=2048 Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 596959 local1.debug] DBG:core:fm_malloc_init: F_HASH_SIZE=2067, fm_block size=16560 Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 362601 local1.debug] DBG:core:fm_malloc_init: params (fc400000, 33554432), start=fc400000 Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 551434 local1.debug] DBG:core:shm_mem_init_mallocs: success Oct 27 09:50:46 ykt1sipprd2 kamailio[3813]: [ID 123545 local1.info] INFO:core:init_tcp: using /dev/poll as the TCP io watch method (auto detected) Oct 27 09:50:46 ykt1sipprd2 kamailio[3815]: [ID 721503 local1.warning] WARNING:core:daemonize: pid file contains old pid, replacing pid -------------------------------------------------------------------------- This email with all information contained herein or attached hereto may contain confidential and/or privileged information intended for the addressee(s) only.
