[Serusers] ReTransmission of CANCELs on 0.9.7
by rupert.organ＠bt.com 08 Apr '10

08 Apr '10

Hi All, Has anyone come up against an issue on 0.9.6 / 0.9.7 whereby a SIP App Server, delivers a CANCEL to the SER. The SER proxies the CANCELs to all the forked endpoints. At the same time it sends "200 Cancelling" back to the SIP App server...(this suppresses CANCEL retransmission from the SIP App server). If one of the CANCELs from the SER to the SIP UA gets lost....the phone keeps ringing. There is no CANCEL retransmission on the SER !!! There is CANCEL retransmission on the SIP App, but when it sends SER replies "no pending branches" Ideally want the SER do CANCEL retransmissions. I understand the timers were rewritten in 0.10.x but this is not hardened version like 0.9.6....any suggestions? Thanks in advance Rupert

[Kamailio-Users] merging users mailing lists
by Daniel-Constantin Mierla 08 Apr '10

08 Apr '10

Hello, I propose to merge the users mailing lists, most of the traffic these days is about 3.0 and even there are 2 stables branches now, they are sync'ed, so same code more or less. For 3.1 will be one stable branch, falvor selection will be only a matter of make command. Lately common useful topics are discussed on those different mailing lists, notifications and knowledge base building require cross-posting, lot of overhead imo. Any other opinion? Like with devel mailing lists, existing email addresses for users ML can still be used, just that end on same ML. Natural choice will be to have users@kamailio and serusers@iptel to be directed to sr-users(a)lists.sip-router.org Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] mc (Midnight Commander) syntax highlighting scheme
by Константин 07 Apr '10

07 Apr '10

Hi all! For easy editing kamailio configuration files I developed a syntax highlighting scheme for mc. Preview The scheme includes basic syntactic structures of Kamailio 1.5, all constants, variables, operators and standart core functions. To install it, download the file kamailio.syntax from attachment and copy it to /usr/share/mc/syntax (for Debian Etch) Next, add to the file /usr/share/mc/syntax/Syntax including: file ..\*\\.cfg$ Kamailio\sconfig include kamailio.syntax Thats all, I hope its helps someone ;) -- Shpinev Konstantin mailto:kks_mail@inbox.ru

Re: [Kamailio-Users] Odd Behaviour with Kamailio + TLS

Yes, i had installed self signed certificates via IE. Bria shows it and validates them during registration process, its the call initiation where it creates problem. Kamailio starts without fix_nated_register. With this function it gives configuration file error. and i had load nathelper.so and that is been confirmed via logs -- Regards, Hemanshu Patel SIS,Ahmedabad.

[Kamailio-Users] Odd Behaviour with Kamailio + TLS
by Hemanshu Patel 01 Apr '10

01 Apr '10

Hi all, I am not sure it is strange behavior or its the desirable one. i have got two phones registered via TLS to kamailio-1.5.X version. phone1: connected via ip1:port1 and having contact value ip1:port2 phone2: connected via ip2:port3 and having contact value ip2:port4 when i have just this two phones i can see 2 TCP connected to my kamailio from both phones from ip1:port1 and ip2:port3. now when i call from phone1 to phone2, rather then using the already established and TLS authenticated connection kamailio creates two new connection from kamailio to ip1:port2 and ip2:port4. mean kamailio creates new connection to the contact value stored in location table of openser DB. Is this the desirable behavior? shouldn't kamailio use the alreay established connection? -- Regards, Hemanshu Patel SIS,Ahmedabad. M: 09601295238

SEMS 1.2.0 released
by Stefan Sayer 01 Apr '10

01 Apr '10

Hello, it is my pleasure to announce that SEMS 1.2.0 has been released. This release again brings many improvements to this fine, free SIP Media and Application server. Get the source at http://ftp.iptel.org/pub/sems/sems-1.2.0.tar.gz Some debian packages at http://ftp.iptel.org/pub/sems/1.2/1.2.0/packages/ Changelog: http://ftp.iptel.org/pub/sems/doc/current/changelog.html Documentation got some new getting started tutorials: http://ftp.iptel.org/pub/sems/doc/current/index.html And there is now an experimental lenny32 vmware image available, configured as webconference server (but usable for all applications with minimal reconfiguration): https://developer.berlios.de/project/shownotes.php?release_id=17393 For more information see the home page at http://iptel.org/sems . Among the most interesting news I would like to emphasize that its powerful state machine scripting engine DSM has matured a lot between 1.1 and 1.2 versions. Thanks to its growing number of modules (including MySQL DB, conferencing, Python and AWS), live script reloading and monitoring, its interfacing to external applications, and its extended script language it has become a good service development and deployment platform. Other interesting additions is a CMake based build system, an in-memory DB 'monitoring' for administrative and applications use, a twitter app, and numerous fixes and improvements all around. Respect and many Thanks go to all contributors and sponsors of the SEMS project. With Best Regards Stefan Sayer P.S. Apologies if you have received multiple copies of this message. -- Stefan Sayer VoIP Services Consulting and Development Warschauer Str. 24 10243 Berlin tel:+491621366449 sip:sayer@iptel.org email/xmpp:stefan.sayer@gmail.com

[Serusers] Registration process : 401 then 403, is it possible ?
by inge 01 Apr '10

01 Apr '10

Hi, I'm looking for a workarround to avoid a buggy CPE. The CPE doesn't stop to try to register after he got a 401 Unauthorized. So this produce a flooding. That's why I'm looking for something to send a first 401 and then a 403 if the registration keep failing. Thanks in advance for your idea. Regards, Adrien

This is the standard Kamailio behavior. Thus, you should apply NAT traversal techniques to instruct Kamailio to reuse the established connection. In short: for each register call fix_nated_register(). For every other request and response call fix_nated_contact(). Thus, if you use the default configuration and apply NAT traversal it should work. regards klaus ------------------------------ Message: 2 Date: Wed, 31 Mar 2010 11:37:27 +0200 From: Daniel-Constantin Mierla <miconda(a)gmail.com> Subject: Re: [Kamailio-Users] Registrar: Save modified contact / set the q value To: Ovidiu Sas <osas(a)voipembedded.com> Cc: NeoTel Lists <MailingLists(a)neotel.at>, users(a)lists.kamailio.org Message-ID: <4BB317D7.4030102(a)gmail.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 3/30/10 8:29 PM, Ovidiu Sas wrote: > If you need this in 1.5, try to fix the contact header and then > forward the REGISTER back to yourself. > The loopback REGISTER should have the fixed Contact header and now you > can call save(). > You will need to tweak a a little bit the config to get everything > right into the usrloc (the loopback REGISTER will come from the server > IP) and it might work. > it works for no nat scenario, otherwise make sure you will get the looped message on the same socket and you add before looping a header with source ip and port (corresponding nat box pinhole) that you store in received avp.

Any PV has a string representation of the value, comparison is done as integer if both PVs are integers, otherwise is done as string. The safe side is to use PV representation of selects when comparing with another PV. PV and selects is another point for the future coherence.
