Kamailio and MySQL/Galera Replication...
by Krishna Kurapati 10 Mar '12

10 Mar '12

Hi, I am trying to setup Kamailio in an Active-Active configuration behind a TCP load balancer. On the database side, looking at MySQL cluster as independent node set vs. Kamailio/MySQL server with Galera synchronous replication. The first configuration requires 3 or 5 servers. 2 for Kamailio and 3 for MySQL. The second probably just requires 2 servers. I am leaning towards Kamailio/MySQL/Galera. Could you share setup/performance issue... Thanks Krish Kura

insert_hf in CANCEL message
by Reda Aouad 10 Mar '12

10 Mar '12

Hi, insert_hf doesn't work for CANCEL messages. It doesn't work either on 487 replies in failure_route.. Why? Is it because they are re-generated on every hop? Is there a workaround? Reda

SIP problems using a comrex Access
by Andy Bosley 10 Mar '12

10 Mar '12

Hi Support, We have a comrex access unit that we have previously successfully used for connections using your SIP service. For some reason now though, we can no longer get the unit to work. We know the username (LCR.ACCESS1) is ok as we can access the account through the website. However, entering the same details in to the comrex fails. The comrex status displays "OFFLINE (Registering)" and does not get any further. Is it possible for you to check that the account is ok and that the unit has successfully been authenticated. regards Andy __________________________ Andy Bosley Supervisor, London Control Room Technology Operations Technology Division, BBC Room 3045, Broadcasting House Tel External: +44 02077 654976 Tel Internal: 54976 http://www.bbc.co.uk/ This e-mail (and any attachments) is confidential and may contain personal views which are not the views of the BBC unless specifically stated.

XHTTP or XMLRPC modules
by Uri Shacked 10 Mar '12

10 Mar '12

hi, i need to start some kind of proccess in my kamailio server (manualy, not by timer). the best way i can think of is to send a HTTP request. i can do it with the XMLRPC module, but i get an error because i dont realy send XML. i try the XHTTP module. but the event_rout[xhttp_request] does not run. i get : 19(2796) ERROR: <core> [tcp_read.c:965]: ERROR: tcp_read_req: bad request, state=7, error=4 buf: POST / HTTP/1.0 User-Agent: Fiddler Host: 10.2.0.55:5060 parsed: POST / HTTP/1.0 User-Agent: Fiddler Host: 10.2.0.55:5060 any ideas?

Backing up htable to SQL table ...
by Krishna Kurapati 09 Mar '12

09 Mar '12

Hi, This is my first time attempt using htable module. How can I back up the htable content in the database incase the server restarts. I saw a htable in the MySQL database. My observation has been that htable module is not automatically backing up to database even though I added modparams to point to the database. Do I need to explicitly backup htable content to database using sqlops or some other mechanism? Thanks Krish Kura

Advice on placement of t_replicate (REGISTER)
by Asgaroth 09 Mar '12

09 Mar '12

Hi Guru's, I'd just like some advice on t_replace and its placement in the routing script. A lot of examples show the following setup: save("location"); t_replicate("backup_server"); Would it not be wiser to have something like: if (save("location")) { t_replcate("backup_server"); } Would there be any scenario where you would want to t_replicate if save("location") fails for some reason? The configuration I refer to is if the location database is in memory. I suspect you may want to replicate all if location is going to db core in case of external failure. But would it matter on the placement if the location was in memory? Thanks

no hangup when there is no network or when the UAC on the other side is power off
by Rabary 08 Mar '12

08 Mar '12

Hi everybody, We are using kamailio+callcontrol+cdrtool+freeradius+mysql to build a voip prepaid based system: . 2 SIP accounts created and one of them is prepaid . we can debit balance when we call with the SIP prepaid account, and when the balance is 0, the call hang up . if we hangup a call session from the prepaid SIP and the balance is not still 0, the call hangup and the system debit the appropriate cost . but when we call from the prepaid SIP account, and we disconnect the ethernet cable or the alimentation of the other UAC, the call don't hangup until the balance is set to 0 . if the phone is still ringing too, when we disconnect the other UAC, the caller UAC still ringing . the 2 uacs and kamailio are in the same subnet network the question is, how can we tell to kamailio to detect if the other side is down and then send bye immediately so thecalculating of the credit will be correct? Thank you. --
