geoip problem, finally solved
by Francesco Castellano 16 May '11

16 May '11

Dear Sirs, I found some problems using the geoip module. My system is a debian squeeze x86_64; and I installed the following packages: Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Nome Versione Descrizione +++-=============================================-=============================================-========================================================================================================== ii geoip-bin 1.4.7~beta6+dfsg-1 IP lookup command line tools that use the GeoIP library ii geoip-database 1.4.7~beta6+dfsg-1 IP lookup command line tools that use the GeoIP library (country database) ii libgeoip-dev 1.4.7~beta6+dfsg-1 Development files for the GeoIP library ii libgeoip1 1.4.7~beta6+dfsg-1 A non-DNS IP-to-country resolver library Using /usr/share/GeoIP/GeoIP.dat as database, the geoip_match("$si", "src") function failed with retcode -2 (NULL from GeoIP_record_by_name()). And finally I found the problem with the GeoIP file DB itself. In particular, compiling a mini program for debug, it said: Invalid database type GeoIP Country Edition, expected GeoIP City Edition, Rev 1 After manually downloading the GeoLiteCity.dat from MaxMind.com everything went fine. I wrote for letting others know my solution, and for asking you if there is a cleaner way to solve it. Best regards, Francesco Castellano

nathelpler module path support
by Asgaroth 16 May '11

16 May '11

Hi All, I have a scenario where our registrar's are sitting behind our sip proxy. The sip proxy is the only system that has access to the outside world. Our registrar's are all on internal private addresses. I am trying to configure our registrar's to perform nat pinging. However, because the registrar's are on an internal address there is no way for the nat ping to get out. I enabled the path option so that the registrar stores the path that the registration comes in on. However it doesnt seem like the nathelper module uses the path parameter to send the outgoing nat ping. I tried the nat ping using sip method INFO, but the same applies, it does not appear to be able to send out via the outbound proxy. I tried to enable the natping option on the sip proxy, but it appears that only registrations with a socket address of the local host will get pinged, or else it is ignored. Is there an option that I am missing for the nat helper module that will enable me to set an outbound proxy for the nat ping messages? Any insight would be appreciated. Thanks

LCR strip and tags (prefix) - Kamailio 3.1
by Alexandre Abreu 14 May '11

14 May '11

Hi, With this LCR release from Kamailio 3.1 the table 'lcr_gw' makes four fields unique: lcr_id, ip_addr, port and hostname. This table is also responsible for setting 'strip' and 'tag' parameters values for the gateways. What I am trying to accomplish is to use different strip and tag values for the SAME gateway based only on what was dialed by the user. In 1.5 LCR for example, if user dialed 444 or 555 and both prefix belongs to the same gateway, I could use gw-sip for 444 (with values strip 1 and prefix 22) and also gw-sip for 555 (with values strip 2 and prefix 33). While this duplicate data, it was possible to play with routes without touching the config file. I am looking for ideas on how to implement that on K3.1 without using ifs, strip and prefix tied (statically) in the script file. As far as I know, for every new lcr_id inserted, I will need a corresponding load_gws(new_lcr_id) in the script. Regards, Alexandre.

[OT] SIP presence and BLF testing tools
by Andrew Pogrebennyk 12 May '11

12 May '11

Is there any framework available to do functional and regression testing of SIP presence and BLF? Ideally I'm looking for a tool for asserting the signaling flow and contents of the XML body (state, version numbers etc), also I'd like to be able to extract the tags and call-id into variables so as to create INVITE with Replaces. Working with message body variables in sipp is a pain. I'm also familiar with SIPr, Net::SIP and a few others, but that doesn't look suitable for someone without much development experience. Spirent is a perhaps a little closer than others in implementing pickup scenario but awkward when you go beyond the default test scenarios. So I'm interested in any information, tips, suggestions, commercial tools etc. I'm asking here 'cause judging from the quality of their BLF&presence OpenSIPS and Kamailio got the testing process just right. -- Sincerely, Andrew Pogrebennyk

core dump
by Dominguez Jover, Ricardo 12 May '11

12 May '11

Hi everybody, We are having an uncontrolled crash in Kamailio 3.1: May 10 20:34:51 tip1 /usr/local/kamailio-3.1/sbin/kamailio[23366]: : <core> [pass_fd.c:293]: ERROR: receive_fd: EOF on 39 May 10 20:34:51 tip1 /usr/local/kamailio-3.1/sbin/kamailio[23327]: ALERT: <core> [main.c:741]: child process 23364 exited by a signal 11 May 10 20:34:51 tip1 /usr/local/kamailio-3.1/sbin/kamailio[23327]: ALERT: <core> [main.c:744]: core was not generated I've read in several posts I must generate the "Core Dump" to know what is happening. I'm trying to generate it in this way. "/etc/init.d/Kamailio" file: if test "$DUMP_CORE" = "yes" ; then 1. set proper ulimit ulimit -c unlimited directory for the core dump files COREDIR=/dumps/ [ -d $COREDIR ] || mkdir $COREDIR chmod 777 $COREDIR echo "$COREDIR/core.%e.sig%s.%p" > /proc/sys/kernel/core_pattern fi "/etc/default/Kamailio" file: DUMP_CORE=yes But the core is not yet generated. Then I've added -w option: OPTIONS="-P $PID_FILE -m $MEMORY -u $USER -g $GROUP -w /dumps/" But core still not generated In "kamailio.cfg" I´ve also added: disable_core_dump=no User running Kamailio is "kamailio" who has 777 permissions in /dumps/ directory. No way. Anyhelp would be appreciated. Cheers, Ricardo Domínguez

Monitor SIP Trunk Usage with MRTG
by JR Richardson 11 May '11

11 May '11

Hi All, So I'm still banging away at monitoring various SIP trunk capacity, the dialog module is working well for this purpose. I am running local server cron job scripts to pull data and put into local flat files for reference. My next step is to pull this data from a remote server and graph with MRTG (this is what I use for most other network monitoring). It looks like I can use the mi_xmlrpc module and remotely query the SIP Router with kamctl commands and parse the results into MRTG. I'm interested in hearing from others that may have already done this and would not mind sharing some scripts or from anyone that has an alternative method. Any guidance or affirmation that this is a good method that works would be helpful. On the MRTG server, I'm using perl scripts for a lot of my data pulling. I am using Kamailio 3.0. Thanks.

Dialog Module Question inbound/outbound count
by JR Richardson 10 May '11

10 May '11

Hi All, Been playing around with the dialog module to help me keep track of SIP trunk utilization, trying to identify how many calls are active on each SIP trunk. My dialog count for inbound calls is 10 (correct) but my outbound calls are always double that and I'm not sure why. Here is a snip of my config: loadmodule "dialog.so" if($rU=~"^111") { dlg_manage(); dlg_setflag("4"); set_dlg_profile("inbound","trunk111"); route(PDT); exit; } PDT lookup for prefix then call is forwarded to dispatcher to route out to carrier through 'route[relay]' route[RELAY] { dlg_setflag("4"); set_dlg_profile("outbound","$rd"); if (!t_relay()) { sl_reply_error(); exit; } exit; } I setup 10 active calls and here are my results: test-sip-router2:~# kamctl fifo profile_get_size inbound profile:: name=inbound value= count=10 test-sip-router2:~# kamctl fifo profile_get_size outbound profile:: name=outbound value= count=20 Also 'kamctl fifo dlg_list' will list only 10 active dialogs. So my question is, why am I getting a 20 count for outbound and only 10 count for inbound? Thanks. JR -- JR Richardson Engineering for the Masses

t_reply MI Datagram Function
by Torge Szczepanek 10 May '11

10 May '11

Hi! In the Documentation of the TMX Module for the t_reply function there is given a list of Parameters as can be seen here: http://www.kamailio.org/docs/modules/3.1.x/modules_k/tmx.html#id2822345 The third parameter is a trans_id. I cannot find any references for this. Is it possible to send a query to the MI Datagram socket, to do a lookup of the trans_id for a given callid or is there any other solution to get this information through the MI datagram socket, to be able to execute t_reply? It seems that t_reply_callid is doing what I want to do, but currently not through the MI Datagram socket and not including a body or new headers. Greetings Torge
