[OpenSER-Users] uaCSTA support in openser

by Hugo Koblmueller

high.all! i'm wondering if there is any support of uaCSTA in openser (planned)? i'm just working on the integration of asterisk (*) environment to OCS 2007 environment, having openSER in the middle (mainly for TCP/UDP translation and smoothing out the protocol deficienes on both sides). in this setup the * having the openSER in front is talking to the OCS (and vice versa) via the OCS mediation server, which is moreorless sending standard SIP messages, which enables normal softphone (integration to *) of the office communicator. this configuration is already working... now i'm planning to go for the CTI integration, where there is no OCS mediation server in between OCS and openSER, doing the translation of SIP/CSTA to SIP. i'm thinking about using openSER for this task, that's why i'm looking for a CSTA module or perl programm, which is capable of this functionality. afaik for the CTI communication there isn't the full complexity of CSTA needed, just a subset mainly for call setup and call clearing. anyone having experience on this topic? thx & cheers -hugo Great Ideas for Small Devices Hugo Koblmueller Senior Staff Engineer Software Development COMNEON electronic technology GmbH & Co.

[OpenSER-Users] [OT] How to handle different DID's in incoming calls for a registered client?

by Iñaki Baz Castillo

Hi, maybe this question is a bit off-topic so I'm sorry for that. My question is about SIP providers using OpenSer that associate PSTN numbers to their local clients (SIP accounts): Usually the client must register to OpenSer in order to receive calls. Then it will appear in location table with "Contact=sip:clientX@IP". Suppose clientX has two PSTN numbers associated in a ENUM entry: +34999000111 +34999000222 When anyone in PSTN world calls to +34999000222 the call will arrive to the OpenSer from a gateway in an INVITE like: INVITE sip:+34999000222@gateway SIP/2.0 To: <sip:+34999000222@gateway> The OpenSer will do the lookup in location table and finally send this INVITE to the clientX: INVITE sip:clientX@IP_clientX SIP/2.0 To: <sip:+34999000222@gateway> The info about the called PSTN number is just available in "To" header, so a way to get different behaviour for each associated PSTN number is matching "To" URI. Is common to do it? which other alternatives are there? Thanks for any comment. Regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[Serusers] ser-0.9.6: modules/postgres bugreport & patch

by Alexandre Snarskii

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)

[OpenSER-Users] OpenSER Advanced Programming Course, Bucharest, Voice System, August 11-14, 2008

by Bogdan-Andrei Iancu

Hi everybody, Following the tradition started last year, the second edition of the "OpenSER Advanced Programming Course" will be held in Bucharest, Romania, starting with 11th of August 2008. The primary goal is the same: to attract more developers to OpenSER and build a higher development squad. There are three major upgrades from last edition: - free participation - there will be no fees for attending to this course; you just need to register. - there will be 4 days course instead of 3 days - the course will contain also a practical work where the students will have the chance to consolidate the knowledge they have accumulated during the theoretical presentations. The course will have a 60% - 40% distribution between theory and practice. The course is dedicated to people willing to learn how to develop OpenSER extensions. The course will follow the idea of writing a new openser module from scratch, with all the dependencies it has from the core: dynamic memory usage, MI interface, registering timers, locking, exporting pseudo-variables, etc The course is sponsored courtesy of : - Packt Publishing (donating 5% of the revenue from the Flavio E. Goncalves's "Building Telephony Systems with OpenSER" book.) - Voice System (logistics and hosting) Teachers from the OpenSER development team will be: - Bogdan-Andrei Iancu - Anca Vamanu As, said, the registration is free, but the class is limited as size up to 17 - 20 people. The seats will be granted on the "first in, first served" policy :). For registration, you need to mail me (bogdan(a)voice-system.ro) or to openser(a)voice-system.ro . You will receive a confirmation response to guarantee your registration. Best regards, Bogdan

[Kamailio-Users] Openser version to run Mediaproxy 2.0

by Nuno Marques

Hello, I was reading the README file on the download page of Mediaproxy and found this statement: This version of MediaProxy (2.0 or higher) cannot be used in combination with any version of OpenSER older than 1.4 or any components of MediaProxy older than 2.0. You must completely upgrade any previous installation of OpenSER and MediaProxy to these new versions. What i want to ask you is if this is really true because Openser 1.4 (kamailio) isn't available yet... Can i use Mediaproxy 2.0 with Openser 1.3.2 or i need to wait for the Openser 1.4? Thanks in advance, Nuno Marques

[OpenSER-Users] XMPP/SIP-SIMPLE Problem

by Cesar Troncoso

Hi everyone, I have a problem with xmpp module. Messages going from xmpp to sip-simple work fine. The problem I have is in the opposite direction (from sip-sipmle to xmpp). If I set fork=no or children=1 in my config file then all messages are sent and received in both directions. This is what I see in the logs: xmpp: invalid content-type 0x300ff xmpp: unable to write to command pipe: Bad file descriptor Any Idea how to overcome this situation? Thanks! Cesar
