Kamailio 4.0.2 as a new Port for FreeBSD

by Oliver Mahmoudi

Hello, I am currently working on porting Kamailio 4.0.2 to the FreeBSD ports collection: /usr/ports, and I just have a few general questions regarding compilation with regard to the extra modules. There are 172 modules that come with Kamailio, and most, however not all of them are compiled by default: # gmake all The base server and the base modules compile fine on my 9.1 release. To really compile all of the 172 modules, Kamailio_4_0_2/INSTALL says that the following external libraries (LIB_DEPENDS I assume) are needed: /usr/ports/databases/mysql-client-* /usr/ports/databases/postgresql-libpqxx /usr/ports/textproc/expat2 /usr/ports/textproc/libxml2 /usr/ports/net/radiusclient This is put down as information for FreeBSD 5.4. Does that still hold current for 9.1? Is there an exhaustive list of all the modules that the all target does/does not compile and - apart from mysql, postgresql - which of the extra modules require which libraries? I would set compile time options accordingly. This would greatly facilitate my work! Oliver Mahmoudi

Kamailio crashing when accessing db tables

by Fabian Borot

Hi, I installed the latest version 4.0 on CentOS release 5.9 , and when running any fifo command that accesses a module's table (lcr, address etc.) or when a call comes in an there is a need to access a table the app crashes. Example: Jul 23 09:07:55 proxy01 kernel: kamailio[16608]: segfault at 0000000000000000 rip 00002b3bcd39a36c rsp 00007fff28ef40d0 error 4 Jul 23 09:07:55 proxy01 ./kamailio[16565]: ALERT: <core> [main.c:788]: handle_sigs(): child process 16608 exited by a signal 11 Jul 23 09:07:55 proxy01 ./kamailio[16639]: : <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 41 Jul 23 09:07:55 proxy01 ./kamailio[16565]: ALERT: <core> [main.c:791]: handle_sigs(): core was generated has any one seen this? Is there something new on this version that I am missing? thank you a lot fabian

get CDR fields in DB

by Jayesh Nambiar

Hello All, Is there no straight forward way of getting the ACC module CDR values into the DB. I mean logging the start_time, end_time and duration in DB directly using some pseudo variables from the config script !! I think, if a dialog is maintained, all the values related to that dialog is anyways available and a manual insert on dlg_end event can be called. But I am only missing the milli-second precision that the CDR module provides !! Thanks for any pointers. --- Jayesh

Re: [SR-Users] trouble counting dialogs

by Gertjan Wolzak

Well, can't stand needing to ask for help... So, I keep trying . found it, well it works now. This is the concurrent route that works: route[CONCURRENT] { xlog("SCRIPT: Conccurrent call check"); if(!get_profile_size("caller","$fu","$avp(nrcalls)")) { sl_send_reply("403", "Call not matching profile"); exit; } xlog("SCRIPT: caller value for $fu is $avp(nrcalls)"); if($avp(nrcalls)>= 1) { sl_send_reply("403", "Active calls limit exceeded"); exit; } dlg_manage(); if(!set_dlg_profile("caller","$fu")) { sl_send_reply("500", "No new channels in this profile"); exit; } xlog("SCRIPT: caller value for $fu is now $avp(nrcalls)"); } Maybe someone else can be helped by it. Thanks.

Trying to send kamailio to a uri derived from a database query

by Will Ferrer

Hi I am trying to make a kamailio script which gets a uri from the database and then directs the call to that uri. Setting the uri with a string (not derived from the database) works just fine: append_branch(); seturi("sip:user@domain"); But I can not seem to pass anything to seturi other than a string. Here are some examples: $var(branch_uri) = $dbr(ra=>[0,0]); append_branch(); seturi($var(branch_uri)); # kamailio won't even start when I try to pass the uri from a variable $var(branch_uri) = $dbr(ra=>[0,0]); append_branch(); seturi("$var(branch_uri)"); # treats the "$var(branch_uri)" as a literal string -- does not evaluate to the the value of the variable $var(branch_uri) = $dbr(ra=>[0,0]); append_branch(); seturi((str)$var(branch_uri)); # kamailio won't start with this syntax inplace The errors that kamailio gives on start up when I have a variable in passed into seturi are as follows 0(16145) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /usr/local/kamailio-4.0/etc/kamailio/kamailio.cfg, line 647, column 12-27: syntax error 0(16145) : <core> [cfg.y:3570]: yyerror_at(): parse error in config file /usr/local/kamailio-4.0/etc/kamailio/kamailio.cfg, line 647, column 28: bad argument, string expected 0(16145) DEBUG: <core> [sr_module.c:674]: find_mod_export_record(): find_export_record: found <sl_reply_error> in module sl [/usr/local/kamailio-4.0/lib64/kamailio/modules/sl.so] 0(16145) DEBUG: <core> [sr_module.c:674]: find_mod_export_record(): find_export_record: found <sl_reply_error> in module sl [/usr/local/kamailio-4.0/lib64/kamailio/modules/sl.so] 0(16145) DEBUG: <core> [sr_module.c:674]: find_mod_export_record(): find_export_record: found <sl_reply_error> in module sl [/usr/local/kamailio-4.0/lib64/kamailio/modules/sl.so] ERROR: bad config file (2 errors) I also tried to accomplish this append_branch($var(branch_uri), "0.0"); t_load_contacts(); t_next_contacts(); # No errors but didn't work I found a way around the problem by making a perl script to allow me set the uri: Perl script: sub rewrite_uri { my $m = shift; my $uri = shift; $m->rewrite_ruri($uri); return -1; } Then I call it like this: $var(branch_uri) = $dbr(ra=>[0,0]); append_branch(); perl_exec("rewrite_uri", $var(branch_uri)); # this works So I have a viable work around but it seems like there is probably something simple I am missing which should let me accomplish this with out having to do a call into perl. Any advice any one can give me would be greatly appreciated. Best regards Will Ferrer

New developer: Lucian Balaceanu

by Henning Westerholt

Hello, I am pleased to announce a new developer for the Kamailio project: Lucian Balaceanu. Lucian works in our 1&1 office in Bucharest and is for some years with us in the company. He worked on several internal projects with our Kamailio stack and will contribute some fixes to the sipcapture and carrierroute module. He will also probably commit some other smaller fixes from time to time. Welcome Lucian and all the best, Henning
