Guidelines to upgrade to 4.0.0
by Daniel-Constantin Mierla 23 Jan '13

23 Jan '13

Hello, the wiki page collecting the guidelines for upgrading from 3.3.x to 4.0.0 is available at: - http://www.kamailio.org/wiki/install/upgrade/3.3.x-to-4.0.0 I just added the SQL statements needed to upgrade the MySQL database, but there is lot of other stuff to be added. Hopefully, anyone noticing changes will add few notes and instructions about how to upgrade. The wiki can be edited if you make an account, it is not required to be a developer to add notes to this page. Would be great if users of postgres will add the sql statements specific for this database type.

Modify IP address in SDP
by Austin Einter 23 Jan '13

23 Jan '13

Dear All When 200 OK to INVITE passes through Kamailio proxy , I want to change the IP address in SDP to a specific IP address. Can this be done by just modifying configuration files or do I need to modify in source code. In case I need to modify source code, which files I need to look at. Kindly provide pointers for said problem. Thanks Austin

Re: [SR-Users] Kamailio as a front-end for TLS-UDP
by Daniel-Constantin Mierla 22 Jan '13

Do no send replies to private address only, keep mailing list otherwise future such emails will be discarded. The contact has to stay the same, because it needs to be the address of the device. Record-Route and Path are designed to take care of routing back to lb, which will use tls to send to device. Cheers, Daniel On 1/22/13 12:26 PM, Anton Kvashenkin wrote: > Thanks for reply.

Kamailio as a front-end for TLS-UDP
by Anton Kvashenkin 22 Jan '13

22 Jan '13

Guys, I've already asked @ G+ Kamailio coummunity but had no answer so I'm asking here: I'm trying to deploy +Kamailio<https://plus.google.com/114984922071338017631> as a front-end for TLS-UDP translation, as a back-end would be +FreeSWITCH<https://plus.google.com/104108080382960591162> . So, is kamailio so smart to fix Contact or Path header for ;transport=tls or it translates only on L3-L4 layer and I should fix those headers manually?

VoIP diner at FOSDEM 2013
by Benjamin Henrion 22 Jan '13

22 Jan '13

Hi, I am organizing a diner for all Voice over IP hackers (Asterisk, Freeswitch, Kamailio, OpenSER, Sipvicious :-), etc…) during the Saturday evening of FOSDEM 2013. There is a complete track at the Telephony devroom as well: https://fosdem.org/2013/schedule/track/telephony/ More infos are registration: http://www.zoobab.com/voip-diner-fosdem Best, -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-3500762 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators."
