Kamailio (OpenSER) v1.5.0 is out – a version with the biggest new features boost since project started…

On March 02, 2008, Kamailio (OpenSER) 1.5.0 has been released. It represents the major version with the biggest new features boost since project was started back in 2005.

A short summary of what the release brings out:

• execute SQL queries against multiple databases and access the results in a fast and natural fashion
• execute config file route blocks on timer
• send SIP requests from config file
• perform HTTP queries from config file – integration with web service
• dialog info presence support – RFC4235
• support for TLS server_name extension (aka SNI=server name indication)
• support for non-blocking logging
• many enhancements to least cost routing (LCR), load balancing (dispatcher) and carrier routing (carrierroute)
• access in config file to both request or reply during transaction processing
• perl-like regular expression support (PCRE library)
• sanity check of SIP message structure
• protection against SIP reply attack
• twelve new modules
• code restructuring in core – slimmer and less exposed to issues
• web management interface – SIREMIS

Asipto SRL has launched the SIREMIS Project, aiming to build web management interface for Kamailio (OpenSER). Later will follow also the sip-router.org project.

Under management of Elena-Ramona Modroiu, the project was developed so far by Asipto – http://www.asipto.com – using OpenBiz PHP framework — the target was to make it easier to extend for non-web developers. Soon, the project sources will be hosted on sourceforge.net SVN (project name: siremis).

Homepage of the project is:
– http://siremis.asipto.com

The first beta release is available for download and includes the 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

Internal design:

• developed on top of a framework: PHP/Web2.0/Ajax
• XML Metadata driven extensions
• Model-View-Controller (MVC) architecture
