Kamailio + Asterisk, what happens when limit for gateway is reached
by Sasa Vilic 12 Mar '12

12 Mar '12

Hello, I have read here about load balancing between multiple gateways by using carrierroute module, but there is one particular question for which I found no answer. Let's say I have two asterisk servers (X und Y), that are my gateways to PSTN. Let we do it simple. Let's say that each gateway supports only one outgoing call at the time and there is no incoming calls from PSTN. Now: Bob calls one number and Kamailio uses X gateway. Alice calls other number and Kamailio uses Y gateway. Alice terminates the call. Alice place a new call, but Bob's call is still in progress. If we were used round robin algorithm, Kamailio would then use X gateway, but X gateway is currently occupied. What shell happen now? And what if Alice didn't tear down call ordinary? What if it her SIP client simply crashed? (Then kamailio would think that there is now free gateway) So the main question is: can kamailio know/detect, how much calls are going over one particular gateway and what can be done when limit for this gateway is reached? Thank you in advance. Kind Regards, Sasa Vilic

Enable session_id in ServerHello for TLS
by Kristijan Vrban 11 Mar '12

11 Mar '12

Hello, how to tell that Kamailio should juse a session_id for tls ? See ssldump output below. I reckon that this is the reason the client i use end with "handshake_failure". Because when is use opensips, there is the session_id, and it's working.

PUA_XMPP: Notify in a non existing dialog
by Dan-Cristian Bogos 10 Mar '12

10 Mar '12

Guys, After my previous discovered issue (Kamailio not happy to talk with Openfire for subscriptions), trying to find work arounds, thought about using pua_mi to enforce subscriptions coming from XMPP side. The following events happen: * I subscribe over mi interface successfully. * Presence sends NOTIFY out. * PUA_XMPP rejects the NOTIFY saying that it does not match an existing dialog. I was wondering where does PUA_XMPP check the existing dialogs and if there is other way to fix my issues? Bellow you can find commands, ngrep as well as kamailio error to syslog. Ta for any kind of tip, DanB """ ### Console ### kamctl fifo pua_subscribe sip:dan@hiddendom.com sip:user01@hiddendom.com presence 3600 ### Trace ### U 2012/03/02 18:17:07.318753 127.0.0.1:5060 -> 127.0.0.1:5060 SUBSCRIBE sip:dan@hiddendom.com SIP/2.0.

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.
