Siremis v3.2.0 is out – the web management interface for Kamailio SIP Server (former Openser) and SIP Express Router (SER). This is a major release, compatible with v3.2.x.

This release brings a large set of new features. Among them:

• SQL-based CDR rating engine for billing purposes
• stored procedure to compute the costs of calls
• Management of billing rates
• longest prefix rate selections
• rating rules can be grouped to allow many sets of values
• time unit is configurable per rating rule
• Management of remote registration records (uacreg table)
• Managment of mtree module (mtree and mtrees tables)
• Management of dialog variables table
• Update of LCR and SIP Trace views for compatibility with Kamailio 3.2.x
• Tools to generate new database table views in a wizard fashion
• create new views to database table with a command line tool in 5 steps
• Charts drawing statistics of accounting records
• graphics to show the evolution of accounting records during the past hours
• graphics to show the types of INVITEs (call setup) during the past hours
• Tables presenting summary of accounting records
• count the number of INVITEs and BYEs in the past hours
• present the top activity of accounting records – e.g., top 5 caller and callee
• more can be added from configuration file
• More SIP server activity charts (e.g., SIP requests traffic load)
• e.g., default chart presents how many requests are received in intervals of 10 minutes
• Buttons to switch to command pannel to reload Dispatcher or PDT records in SIP server cache
• once new records are added, in two clicks they get in the cache of SIP server
• Views for managing global black lists table
• Many improvements to user interface
• selection of local domain is done via select box or picker form (e.g., in aliases, user preferences, pdt, …)
• selection of local username is done via picker form (e.g., user black lists, user preferences, aliases, …)
• group names can be set in config file and selected from a list box
• many static values are given as option to select from a list box (e.g., dispatcher flags, lcr options)
• More targets in Makefile to make administration easier

Step by step installation tutorial, screenshots and demo are available on the web at:

• Installation Tutorial
• Screenshots
• Web Demo for Siremis 2.0 - v3.2.0 is built on same core framework, just new features were added (thus more options in the menu)

Development guide for Kamailio SIP Server has been updated for v3.2.0 – it goes through internal components, presenting the APIs for pkg/shm memory, locking/synchronization, config file interpreter, database connectors, a.s.o., as well as guiding how to write a new module.

There is a section trying to collect hints about upgrading a module developed for old versions 1.x to newer architecture and APIs in versions 3.x.

The tutorial is available online at:

A mirror is hosted at:

Looking forward to your contributions to Kamailio and SER SIP Servers!

On October 18, 2011, v3.2.0 has been released – this release is a result of more than 10 months of development and 2 months of testing from the teams of Kamailio (OpenSER) and SIP Express Router (SER) projects. The packaging and official versioning for 3.2.0 was done so far only for the Kamailio flavour.

Among topics to be approached:

• internal architecture of Kamailio/SER SIP server
• SIP parser
• memory manager
• locking manager
• database API
• configuration file language structure and interpreter
• RPC/MI control interface
• pseudo-variables and transformations framework
• module interface
• how to write your own extensions in C as module
• inter-module APIs – transaction management, SIP SIMPLE Presence, asynchronous processing, a.s.o.
• working with embedded interpreters for high level programming languages: Lua, Perl, Python

Who should attend:

• VoIP/Telecom developers intending to write own extensions to Kamailio SIP Server
• VoIP/Telecom administrators interested to learn about the internals of Kamailio SIP Server in order to know how to optimize the SIP routing and build proper configuration file
• VoIP/Telecom professionals interested to learn about Kamailio SIP Server, how and where can it be used, its current features and future development

The event is a good place for networking with other professionals from VoIP/Telecom and Real Time Communications fields, past similar events having dozens of attendees.

The price per attendee is 250 USD.

Number of seats is limited and access will be granted in first come first served fashion.

Registration or requests for more details can be done via:

• registration web form – click here for it
• or email to: registration [at] lists.sip-router.org .

Here are some stats I thought of:

• type of usage: production, evaluation (testing), research
• number of subscribers (phone lines)
• percentage of phones behind NAT
• number of calls per month
• number of call minutes per month

I am not looking for exact numbers, but rough estimation (e.g., about 10 000 phone lines, …). Of course, some of the metrics don’t apply always (e.g., if you do termination routed through SIP server, you don’t have subscribers, but just calls traffic). Those doing deployments, can make one summary of statistics for all instances. You may send other “interesting” statistics you think they worth publishing.

Again, this is voluntary, naming is not required. I hope only those giving real number will write back — I will try anyhow to figure out if someone is just dumping fantasy numbers. If privacy is really a big concern, from case to case, everything can be done under NDA.

Send the statistics or contact me for further details per email at: <daniel [at] kamailio.org>. Many thanks in advance to those that are going to participate in this survey!

There is no participation fee for the conference day, registration can be done via web form. At this moment there are about 20 special guests and 14 speakers, with participants from 15 countries.

If you use SER-based applications (like ser, openser, kamailio, openimscore, …) and want to present about it or you want to sponsor the event in exchange of advertising through project channels, contact us via event registration form.

It was done by the same developer that started the project and committed the 1st one, Andrei Pelinescu-Onciul:

git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -1

512dcd9    Andrei Pelinescu-Onciul    Mon Sep 3 21:27:11 2001 +0000    Initial revision

The 15000th one is:

git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -15000 | tail -1

8a90dd3    Andrei Pelinescu-Onciul    Sat Jun 11 11:24:05 2011 +0200    core: remove unused variables + coding style

This number of commits is counted only for development branch (GIT master), thus it does not take in consideration the branches of stable releases. That will make the number of commits in the project higher, but the target was to show only the main stream development evolution, not the fixes in stable branches.

Note that there are personal developer branches holding code commits done in the past and to be merged in GIT master branch in the near future, so the number 15000th commit may be different when checking again later. However, as a marker in the history of the project, Andrei’s commit is the first in master branch to hit the 15000. The link to the commit via web GIT viewer is here.

• SER’s 15000th code commit

You can also check the history of SER/Kamailio commits tracked by Ohloh here.

Be ready to party with us in September at the 10th project anniversary and watch us for the 20 000th commit!
