ASYNC Module

by Aaron Hamstra

We just updated our development environment from 4.2.2 to 4.2.5 and started noticing the server sending a 500 I'm terribly sorry, server error occurred (1/TM) error back as soon as the async_route block gets called. I have removed everything from our async route other than an xlog statement trying to determine if something in that route block was causing the 500 to occur. It still happens even with only the xlog. If the async_route is not in the config, then the server does not send the 500 response. We rolled back to 4.2.2 and the problem no longer occurs. I have attached a sip trace of the messages. I believe the relevant parts of our config are below, please let me know if you need more from the config however. Any ideas? async_route("PUSHJOIN", "2"); -------------------------- route[PUSHJOIN] { xlog("L_INFO", "Does it get here?\n"); exit; } Thanks in Advance, Aaron

by Al S

Hi, lookup("location") functions extracts username from Request-URI and relay INVITE without any username, causing UAC sends a CANCEL message. Is the function suppose to replace uri with "contact" field in the found entry in "location" table? INVITE uri arrives at Kamailio:Request-Line: INVITE sip:8181111111@example.net:5060 SIP/2.0 INVITE uri leaves Kamilio:Request-Line: INVITE sip:10.10.10.1:5060 SIP/2.0 lookup("location") function finding match and returns 1: $rc=1 entry in "location" table for this call:*************************** 1. row *************************** id: 104 ruid: uloc-557ad93a-2d6-1 username: 8181111111 domain: NULL contact: sip:8181111111@10.10.10.1:5060 received: NULL path: NULL Any help in this regard would be greatly appreciated Al,Thanks

How to prevent multiple registration entries in module ims_registrar_scscf

by jyaim

Hi all, I have an issue with mobile devices which get a different IP address each time they lose network. The scscf keeps the registration datas from the previous registrations, and forks requests toward all known identities. Is it possible to override the contact address at each register and keep only the last registration address per impi ? Thanks Regards JM

Problems with http_query(POST)

by Joao Alves

Hi, I'm finding a problem submitting a HTTP POST using the http_query(). Currently running on kamailio version: 4.1.8 on Debian wheezy. Normally this command has been worked fine, but since the body of the message increased (the POST data size is around 2000 bytes ) I start to get the following problem: 8(49381) ERROR: <core> [pvapi.c:1338]: pv_printf(): no more space for spec value 8(49381) ERROR: <core> [pvapi.c:1347]: pv_printf(): buffer overflow -- increase the buffer size... 8(49381) ERROR: <core> [sr_module.c:1696]: get_str_fparam(): Could not convert the PV-formated string to str 8(49381) ERROR: utils [functions.c:112]: http_query(): cannot get post value I've searched on how to increase buffer and found some global settings that could be directly, however the problem persist despite having set very high values for those: pv_buffer_size=32768 tcp_rd_buf_size=32768 maxbuffer=262144 Can someone assist and suggest a solution.

Mark CANCEL of one fork when another answers the call - old Kamailio

by Sebastian Damm

Hi, I'm looking for an option to mark CANCELs which are generated locally by Kamailio after receiving a 200 OK for another fork of the same call. In the tm module documentation I found the option local_cancel_reason which enables this. This option is available (and turned on by default) in newer Kamailios. But we have a legacy system still running 1.5 (and we don't want to upgrade it anymore, it will be obsolete pretty soon), which doesn't have this option yet. Is there a possibility to add a header to this locally generated CANCEL via some function in the config file, too? Thanks in advance. Best Regards, Sebastian

Kamailio LCR module memory concern

by Ali Taher

Hello, I'm using LCR module where I have 44 million rules and 13 million rule targets (not all rules have destinations). Noting that I'm running Ubuntu on virtual machine with 8GB allocated memory. When I'm setting lcr_rule_hash_size parameter to 268435456 (2 power 28) I got the following error : "no memory for rules hash table" in the log , noting that when I run ipcs -lm command I got max total shared memory shared memory (kbytes) : 8388608. When I'm setting lcr_rule_hash_size parameter to 1024,meaning 1024 rules will be fetched from the database (please correct if I'm wrong) Kamailio takes around 2 minutes and 30 seconds to start , which is worrying for me :( Please advise how many rules Kamailio can support (if 8 GB RAM are allocated to the server) , and what size every rule takes in the hash table built in the shared memory. Thanks, Ali

Releasing Kamailio v4.3.0

by Daniel-Constantin Mierla

Hello, I am considering to release next major version of Kamailio (v4.3.0) next week, on Wednesday (June 10) or Thursday (June 11). The pool of things to fix is minor, Victor already updated deb packaging for 4.3, left to do: add docs for 4.3 series in wiki, prepare RPM packaging and build proper 'what is new' list of features. Testing didn't reveal new issues for me in the recent past as I run in two servers with live traffic. If you have issues with 4.3 branch, be sure you report them on Github tracker: - https://github.com/kamailio/kamailio/issues Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
