The conference will focus on:

• the achievements of SIP Router Project so far
• the role of Kamailio (OpenSER) release within the SIP Router project

VoIP Security, Asterisk, SIP, Brute Force Attacks, Explained By John Todd Of Digium.

VoIP Security snapvoip.blogspot.com
My thoughts when I read the article saying  “Asterisk attacks are endemic” were ????*&^ and I also knew that John Todd knew what he is doing. So I let the article pass as I was certain it was not the case.
Today Todd has posted an article explaining the misinterpretation of his thoughts and the verbalization of the same.

My comment in the article was not that “Asterisk attacks are endemic”, but that SIP-based brute force attacks are endemic.  Every SIP system that is open to the “public” Internet is seeing large numbers of brute-force attacks.  Sites that have weak username and weak password control will be compromised – this is little different than email accounts being taken over by password-guessing systems and used for sending floods of email.  The significant difference is that when someone takes over a SIP platform to make outbound calls, there is usually a direct monetary cost, which gets people’s attention very quickly.

We all know that Asterisk is used world over and is the favorite SIP based telephony platform is likely to attract people who are interested in hacking or attacking the system. But we also have seen security measures taken by Asterisk as well. Just like the one released day before yesterday, AST-2009-07, where the advisory and the fix was released simultaneously.
But what Todd wrote makes sense and as Asterisk, Broadsoft, Cisco, Kamailio, OpenSER, FreeSwitch, Avaya are all vulnerable to brute force attacks and every bit of  information will help. Whether it is news worthy or not.
Asterisk and SIP Security Redux

SIP Router Org, ASIPTO and SIP Router Trining

SIP-ROUTER.ORG

I am glad that the original SIP Router, (SIP Express Router, SER from IPTEL org, where I got my first free SIP Account) is in the limelight again with the corporation with the Kamailio (OpenSER) the original fork from the SER project in 2005. OpenSER project separated into two a while ago into Kamailio and OpenSIPS. I have been using testing both while being l)oyal to SER, where I learned to sip SIP in 2001, where no other open source SIP servers existed (If they did, I did not know.)

 

The SIP Router Project will bring together a common collaboration framework for any project originating from SIP Express Router (aka SER), referred further as x-SER projects. The projects that joined the initiative so far are: SIP Express Router (SER) – the initial project started in 2002 and Kamailio (OpenSER).

In any case I am looking forwared to the SER 3.0 and Kamailio 3.0 which is slated to be released soon. Good work and cheers to both the teams.

Another bit of news that I would like to bring is that ASIPTO will conduct a SIP router training known as SIP Router Masterclass in November 9-13, 2009 in Berlin, Germany.
The teachers are non other than,

Daniel-Constantin Mierla – co-founder of OpenSER/Kamailio project in 2005, currently core-developer and member of project’s management board

Olle Johansson – Asterisk developer and member of the Digium Asterisk Advisory Board.

 From a post on ASIPTO;

The course targets system administrators and people that act in large VoIP/telephony network services, as well as integrators of VoIP, instant messaging and presence with web 2.0 or similar technologies.

Learning to configure the SIP server is not easy, but is the key for a successful and secure  VoIP business. The flexibility of SIP routing engine allows you to implement in no time innovative services, IP telephony, Instant Messaging, Presence and beyond. Asterisk comes to complete with rich media services and applications. Doing everything designed right and scalable saves time and money.

We create the opportunity for you, guided by experienced instructors, to learn how to build an Unified Communication platform from scratch using the SIP server engine and Asterisk.

SIREMIS Project, Web Management Interface For Kamailio (OpenSER).

http://snapvoip.blogspot.com/
Kamailio has announced SIREMIS - new web management interface for Kamailio (OpenSER) and SIP-Router.org. The project is headed by up to this point by Apisto, utilizing OpenBiz PHP framework. The idea behind the plan was to make it easier to involve developers from all walks. Following the open source nature, the project sources will be hosted on sourceforge.net and developers will have access to SVN code repository. (project name: siremis). Currently the project is hosted at Asipto.
I have not used the product but have seen some screenshots which to say the least, very promising.
The beta release include following features:
- subscriber, database aliases and speed dial management
- location table view
- dispatcher, prefix-domain translation and least cost routing (lcr) management
- access control lists (user groups) and permissions management
- accounting records, missed calls and call data records view
- hash table, dial plan table and user preferences table management
- off-line message storage view
- it was tested with MySQL but should support other sql-like DBs
Release note.

Enhanced LCR Module For Kamailio

http://snapvoip.blogspot.com/
Kamailio, the ex OpenSER team has released an enhanced version of lcr module, in to the development trunk.
The new high-performance implementation keeps lcr information in an in-memory hash table. The size of which could be managed with the new parameter 'lcr_hash_size'.
The 'weight' field in 'gw' table allows to assign a gateways according to weight in a group. Among other enhancements, lcr_reload function is now executed under a lock minimizing race conditions.

You can learn more about what is new in upcoming Kamailio 1.5.0 at Kamailio Dokuwiki site:

If you are a developer, then download trunk version of Kamailio via SVN:

svn co https://openser.svn.sourceforge.net/svnroot/openser/trunk kamailio

OpenSIPS At SIPIT and My Loyalty!

Solarion seems to be head over heals with OpenSIPS but after digging deep into the story behind OpenSIPS, I tend to siding with Solarion. Like Solarion, I also got my SIP feet wet with SER. Even though stiff and don't feel like at home was all around IPTel, We hung around because there were not many other resources providing SIP down to nuts and bolts SER did.
So When OpenSER came out with new development and management philisophy, I was over the wall! I started converting all my SER servers (quite a few) in to OpenSER servers. Even while doing so I could not belive the version numbers climbing up. I was so used to SER being stuck on version 0.7 I think, I had a party when OpenSER reached version 1.0. Because I knew then SER was history stuck is version 0.9.
Now the tables have turned and for what ever the politics or other reasons, OpenSER has been forked and two new entities, OpenSIPS and Kamailio (I feel good now as I thought I was bad at picking names!).
If you have noticed, I still have a link to SER, on the links on the right. I guess it will be there for giving me first real taste of SIP. But otherwise, I have moved on. And like the Solarion, I am leaning towards OpenSIPS and I will be playing with OpenSIPS 1.4 this weekend. May be Kamailio afterwards.

But I know where I will see OpenSIPS. as they have promised to be at SIPIT, so will I. I will see my Mom and then drive to Lannion as I have not done this great past time I learned in the USA, Driving long distances! Yes I know it is expensive and environmentally incorrect, but like Mr. Gore, I pay for my Carbon foot print else where in the world, I have done so even befor being green became the buzz word of the century.

So I picked up the following information from OpenSIPS site;

OpenSIPS at SIPIT

OpenSIPS project is registered to participate the 23th edition of SIPIT - SIP Interoperability Test event in Lannion, France, October 13-17, 2008.
Compliance and interoperability are essential parts of project testing and participating to such large testing events is a natural step in the QA process.

If there are people interesting in being part of the OpenSIPS test team, please let us know (via the users mailing list).

KAMAILIO v1.4.0 Released

Kamailio Server Version 1.4.0 has been released by the Kamailio (formally OpenSER) with new features since OpenSER v1.3.0 as well as improvements to existing components. Much effort was put in code cleanup and stability and new features in core and old modules were added while other 6 new modules were introduced.
You will find the release here.
This gives me a problem now in writing. What used to be SER vs OpenSER, now becomes SER vs OpenSIPS vs Kamailio!
