when mySQL is unreachable ...
by Robert R 13 Apr '10

13 Apr '10

Hi, My Kamailio server uses an external mysql database with perl script to proxy traffic. When mysql server is unreachable, Kamailio do not respond with 100 Trying and instead responses with 484 (Address Incomplete) to the INVITE message. Is this a normal behavior? I need to response with 503 when mysql is unreachable. Can I do it in kamailio.cfg or I need to implement it in the perl script? Thanks, R

Compiling and installing sip-router with some SER modules
by Steven C. Blair 13 Apr '10

13 Apr '10

I'd like to build the latest version of sip-router from source but include server modules from the modules_s directory. I thought the command 'make include_modules="modules_s/permissions modules_s/pike modules_s/ratelimit modules_s/sms modules_s/sanity" ' would do the trick but it doesn't. Instead all modules from the modules_s are built. Is there a way to compile and install the core + modules_s/(permissions,pike,ratelimit,sms,sanity) ?

[OT] Nagios SIP Plugin
by Iñaki Baz Castillo 13 Apr '10

13 Apr '10

Hi, I've coded a SIP plugin for Nagios. There is some other similar plugin but it's less customizable and less powerful. Homepage: http://dev.sipdoc.net/projects/sip-stuff/wiki/NagiosSIPplugin Features: - SIP UDP and TCP transport protocols. - Customizable parameters (From URI, Request URI, server address, local UDP port, timeout internal). - The replied status code can be matched against an expected value to be considered as valid. Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Calling number Routing possibility in 1.5rel.
by Maciej Bylica 13 Apr '10

13 Apr '10

Dear ALL, I am playing around with kamailio 1.5. Could somebody explain me what module best fit to route the call on the basis of number A (calling number). What is more all rules should be able to be modified directly from mysql db. I've run through 3.0 modules and figured out that there is drouting module which is really great, but is it present in 1.5 rel? If negative, what other modules can be used. Thx in advance, Maciej.

My wish

Allow cfg_get parameters to be used as modparams, too, so I can define one set of global database properties and pass them as db_urls to every module that uses one and also to 'sqlops' as an 'sqlcon', and similar things. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

Close TLS connection and Registrar Server (Kamailio V1.4.x)
by edson.gomes.leme 11 Apr '10

11 Apr '10

Hello, We are using Kamailio V1.4 with TCP/TLS. The Kamailio is configured the TCP lifetime to the expire value of the REGISTER by using the tcp_persistent_flag parameter of Kamailio's registrar module. Note: The SIP proxy should not close the TCP connection as it is not capable of opening a new one. Kamailio tries to open a TLS connection to the client. The Kamailio should use the existing TLS/TCP connection that was established by the client during registration. We are applying NAT traversal techniques to instruct Kamailio to reuse the established TCP/TLS connection. Example: for each register call fix_nated_register(). For every other request and response call fix_nated_contact(). I have got one SIP phone registered via TLS to kamailio-1.4.X version with Expires = 3600. phone1: connected via ip1:port1 and Expires = 3600. Example: After 15 minutes TLS connection is closed. The SIP Phone opens a new TLS connection and registers via TLS to Kamailio. Thus, we have the following records on the Registrar Server (Kamailio): phone1: connected via ip1:port1 and Expires = 2700 [3600 – (15 min * 60 s) = 2700]. phone1: connected via ip1:port2 and Expires = 3600. Is this the desirable behavior? Shouldn’t the Kamailio (Registrar Server) delete the below registry? phone1: connected via ip1:port1 and Expires = 2700 [3600 – (15 min * 60 s) = 2700]. Best regards!
