Reminder: VUC Today, SIP Router Project
by Daniel-Constantin Mierla 19 Mar '10

19 Mar '10

Hello, a kind reminder for today's audio conference scheduled for 16:00GMT. Check the start time for your zone at: http://vuc.me/next After presenting the achievements so far within SIP Router, with what is new in 3.0.0 release and development version, you have an unique opportunity to ask questions to: - Andrei Pelinescu-Onciul, the creator of SIP Express Router (SER), the architect behind the core (transport layers, memory management, asynchronous processing, timers, etc), who will be also able to answer anything from project's history started in 2001 - Alex Balashov, Kamailio management team member, experienced consultant in building large SIP platforms - myself, as co-founder of Kamailio (OpenSER) You can join via irc on #vuc (note that some of us started to hang out on #sip-router) channel at irc.freenode.net. Dialing to VUC is possible via sip, skype, pstn, web page and more, see: http://vuc.me Five hours to go right now, hear you then! Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

Kamailio - SIP Router on GSoC 2010
by Daniel-Constantin Mierla 19 Mar '10

19 Mar '10

Hello, I have the pleasure to announce that our project has an accepted application for Google Summer of Code 2010. The proposed application was done within SIP Communicator Organization and is related to extending the presence server for conference calls notifications. See more: http://www.sip-communicator.org/index.php/GSOC2010/Kamailio4575 http://www.sip-communicator.org/index.php/Development/Gsoc2010 The friends from SEMS project will be part as well, with separate application, implementing the audio mixer part. More details will be published soon. Start thinking about good candidates (they must be students (college or university)), we need them to get the project accepted for implementation. Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

Revision: 5996 http://openser.svn.sourceforge.net/openser/?rev=5996&view=rev Author: mariuszbihlei Date: 2010-03-19 10:35:11 +0000 (Fri, 19 Mar 2010) Log Message: ----------- modules/carrierroute Documentation for cr_reload_routes in case of carrier mapping is changed. We do not allow cr_reload_routes when a carrier name has changed, so documentation states now that a restart of the server is to be done. (Server craches in some cases when carrier name has changed and cr_reload_routes is issued This affects only 1.3 version of carrierroute) Modified Paths: -------------- branches/1.3/modules/carrierroute/doc/carrierroute_user.sgml This was sent by the SourceForge.net collaborative development platform, the world's largest Open Source development site.

Opinions? Interesting idea. Let me ask two questions: (1) I re-checked when dialog state is modified exactly for responses (and believe I have to doubt what I initially claimed to be true): According to dlg_handlers.c, dlg_onreply() is called right before a response is forwarded, after it was forwarded, and when the associated transaction is terminated. (tm callbacks TMCB_RESPONSE_PRE_OUT, TMCB_RESPONSE_FWDED, and TMCB_TRANS_DELETED, respectively, in Kamailio 1.5. The 3.x branch seems to have renamed TMCB_RESPONSE_PRE_OUT to TMCB_RESPONSE_READY and TMCB_TRANS_DELETED to TMCB_DESTROY. Correct me if this wasn't just for the looks.) So, taking into account that (serial and parallel) forking proxies will *forward* responses only when all forking attempts have finally failed or one succeeded, wouldn't that automatically implement your "dialog-outs will properly adjust dialog-in's state" approach and render dialog-outs unnecessary? Or am I wrong on the assumption how forking works? (2) How would your approach deal with unconfirmed requests traversing the same proxy multiple times, i.e., what has been denoted as "spiraling" in this thread, as in this example: UA1 --> P1 --> P2 --> P1 --> UA2 Will that result in the creation of two dialog(-in)s? Cheers, --Timo

building flavours
by Daniel-Constantin Mierla 18 Mar '10

18 Mar '10

Hello, I was thinking to get an easy way to build flavours completely out of the same source tree, one of the benefits is to have only one branch for future releases. make FLAVOUR=abc cfg does most of the job. The missing pieces are manual pages and some doc files (e.g., INSTALL). My idea is to restructure a bit the pkg content: pkg: | +--- default -+-- docs (Install, man pages, etc) | | | +-- debian | +-- rpm | +-- ... | +--- abc -----+-- docs (Install, man pages, etc) | | +-- debian | +-- rpm | +-- ... | make FLAVOUR=... cfg will copy the docs files from pkg/flavour/docs in source tree root. 'default' can be 'sip-router' to match the flavours values right now. In source tree root plan have README.first where to mention to run make cfg (which is called anyhow by simple 'make') first to get INSTALL, etc ... Other opinions?

Re: [sr-dev] improving the dialog module

Hi! I have not followed the whole discussion. I just had an idea which might be useful: Why not hook up dialog module with tm module? Tm module already knows the state of forked INVITE transaction, which ones are in early states, and which branch is the winner. regards klaus Am 15.03.2010 14:00, schrieb Iñaki Baz Castillo: > 2010/3/12 Timo Reimann<timo.reimann(a)1und1.de>: > >> If so, my major concern with this approach is that it will break dialog >> callback functionality.
