Kamailio - change SIP type
by Leky Shakur 11 Dec '14

11 Dec '14

Hello, Is is possible to change SIP message type? Example: Server A sends Kamailio SIP INVITE message, can I change this SIP INVITE to "302 - MOVED" (and reuse data from SIP INVITE) and send it to Server B? Does anybody have any example? Best Regards.

Kamailio Truncating timestamp of sip message?
by Heenan, Timothy Steven 10 Dec '14

10 Dec '14

Greetings, I've recently run into a rather strange issue where, in response to an INVITE sent by Kamailio, I'm receiving a 183 Session Progress and SIP 200 OK response about .000050 seconds apart (.05 miliseconds) . Kamailio is choosing to forward the SIP 200 OK ahead of the 183, as if they had arrived at the same time and is prioritizing the 200. Is there a truncate limit on timestamp values? Is this possibly adjustable? Thank you in advance, -Tim ---------------------------------------… [View More]

RFC: infrastructure upgrade - git, tracker, ...
by Daniel-Constantin Mierla 10 Dec '14

10 Dec '14

Hello, as most of you know, we have a rather distributed infrastructure, with servers provided from different companies or persons. We came to the time when one of the servers is too old and considered to be decommisioned, so we have to decide how to move on. It is about sip-router.org, who was offered/sponsored by courtesy of Jan Janak. From project point of view, the server hosts: - git repository - bug tracker - website and wiki under domain sip-router.org Given that no matter what we … [View More]like, there is work to do, I am looking to see what are the best options out there for everyone involved in the project. The sip-router.or wbesite and wiki, which are not really updated anyhow, will be relocated as virtual host in kamailio.org server and made static for historic purposes. For git and tracker, I thought of two variants: 1) move to use an external hosting service - the first candidate and perhaps the only to be considered is GitHub, we have there already a real time mirror of git repository. Then we should get a read only mirror to kamailio.org. If the tracker on github is good enough for everyone, then we will use it. I could see quickly that lot of kamailio developers already have an account on github. 2) get a new server and relocate those components there. It will need to be configured from scratch and the components eventually updated to use latest versions. In case of tracker, we have eventually to re-evaluate if flyspray worth keeping, as we had several discussions, due to the fact that the project doesn't seem to be very active. My personal preference at this moment is 1), given that offloads administration works from project. For 2) we will need someone to commit to a sysadmin job for long time. As probably you noticed lately, serious security vulnerabilities can appear and someone needs to take care of proper maintenance of the server. I don't want to get all services on kamailio.org, as it has other critical components (mailing lists, releases, website, ...) and messing it or overloading doesn't make sense. There is no real pressure to come to a decision, we can still rely on the server for a while, but I would rather not postpone it for long. While users are encouraged to give their opinion, I feel that existing developers should have the main role in decision, being something that impacts them directly. Your preference? Any other opinions?

Hi all!

Sanity Module - no 400 Bad Request message when no VIA header
by Kowalski Piotr 3 - Hurt 10 Dec '14

10 Dec '14

Hello everybody, We are facing a problem with Sanity Module. We need to use it to force Kamailio to send back 400 Bad Request message when there's no VIA header within INVITE. How can we achieve this? In our opinion there's no possibility to set this easy. We get no answer from Kamailio when sending corrupted INVITE (with no VIA headers). Many thanks for your help.

Kamailio Crash
by Kristian Kielhofner 09 Dec '14

version: kamailio 4.1.6 (x86_64/linux) 58746c I looked through 4.1 commits but didn't catch anything that looked like a fix for this but it's a very real possibility this is a duplicate (again). Any thoughts (backtrace attached)? Thanks! -- Kristian Kielhofner

Contact Header User
by Marc Soda 09 Dec '14

09 Dec '14

Can someone recommend a way to extract the user part of a Contact header URI? Right now I'm just trying to pass it to xlog(). I have tried: - xlog("L_NOTICE", "$(ct{uri.user})"); This gives me an empty string. - xlog("L_NOTICE", @contact.uri.user); This gives me an error starting Kamailio: "function xlog: parameter 2 is not constant". Note, I can't seem to get any select working, for example, @ruri gives me the same error. Any suggestions? Thanks, Marc

Hi, The purpose of projet is to implement a VoIP secure solution with Kamailio as core IMS network. In this project VoIP call will be established with zRTP.

How is managed the SBC failover mecanism ? is there SBC backup ? What is the status of context registered in Kamailio (P-CSCF &… [View More]
