Call connection from one server to another
by aawaise 09 Sep '14

09 Sep '14

Hello, I want to deploy two kamailio servers, both using same MYSQL database placed on Server 2008. Both are using different static IP's. Hopefully, I can add two A records in DNS server, both against same domain name, pointing to two different IP's to which two servers are attached. My question is that in load balancing scenario if user 1 is attached to server 1, and user 2 is attached to server 2. How can user1 call user2. Because request will go to server 1 to which user 1 is attached. But it wont be able to locate user 2 because it is not connected to server1 (but connected to server 2). I am using same domain name for two servers. What can be done in kamailio to solve this issue ??

dialog match on loop back
by Kelvin Chua 06 Sep '14

06 Sep '14

hi guys, i'm running out of ideas i have a situation where I need to generate 2 sets of entries INVITE,BYE in acc (acc_db_request won't cut it) it's when a DID should be redirected to a user outside my domain, I need to generate a cdr for DID and another CDR for the outbound call. what i am trying to do is loop it back to itself before routing it out. the idea is kamailio assigns the DID call to a dialog. then the outbound call will be assigned to a separate dialog after it receives the loopback. this is not happening since the from_tag, to_tag and the callid are all the same. kamailio treats this call as just 1, not 2. is there any ideas out there to work around this scenario?

Adding IPs from which 503 messages originates to a database
by aft 06 Sep '14

06 Sep '14

I'm trying to configure HOMER sip capture server to do some accounting of the cases when "503 Service Unavailable" message arrives from capture agents. I've implemented the following to record the source IPs from which 503 message originates. onreply_route { ...................... ...................... ...................... else if(status == "503") { if($sht(a=>alarm::503) == $null) { $sht(a=>alarm::503) = 0; $sht(a=>alarm::$si::503) = 0; } xlog("Got 503"); xlog("($sht(a=>alarm::$si::503))"); $sht(a=>alarm::$si::503) = $sht(a=>alarm::$si::503) + 1; } ................... ................... ................... The following route supposed run periodically to update the databases. } route[TIMER_STATS] { ..................... ..................... xlog("($sht(a=>alarm::$si::503))"); if($sht(a=>alarm::$si::503) > 0) { sql_query("cb", "INSERT INTO alarm_data (create_date, type, total, description, source_ip) VALUES(NOW(), 'Too Many 503', $sht(a=>alarm::$si::503), 'service unavailable', $si)"); xlog("adding stuff to db"); } $sht(a=>alarm::503) = 0; $sht(a=>alarm::$si::503) = 0; } But the xlog("adding stuff to db") never executed. But in the first block of code, the log message to print the value $sht(a=>alarm::$si::503), which is shown to be non zero. Don't understand why its not working. -- -Cheers -Arif

Kamailio as a front end?
by Tom Johnson 05 Sep '14

05 Sep '14

I am looking for something that would act as front end to various SIP PBX systems. I am using Asterisk, but compatibility with others might be necessary. What I want to do is pass subscribe requests with certain content types to an external program (written in Java) and the rest onto the SIP PBX. Can Kamailio do this and if so, is there some example config files somewhere that I can look at to get started?

mt_match avp behavior
by Juha Heinanen 05 Sep '14

05 Sep '14

looking at the code, i appears that mt_match does not initialize pv_values pv when it stores matched values thus keeping possible existing values from previous calls. is that intended behavior? readme uses word "store". -- juha
