SIP Router Bootcamp, Berlin, Germany, Sep 1-4, 2009

Next SIP Router Bootcamp will take place at the end of the summer, on September 1-4, 2009 in Berlin, Germany.

Teachers:

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.

By end of 2008, Kamailio (OpenSER) and SIP Express Router (SER) started a joint collaboration under http://sip-router.org project, bringing together valuable developers and architects of SIP servers. Kamailio 3.0 and SER 3.0 (to be released soon) become compatible in terms of configuration file and extensions.

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.

Kamailio (OpenSER) v1.5.0 Released

On March 02, 2009, 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.

Release 1.5.0 comes after a shorter development period than usual – about five months of coding and more than one month of extensive testing, but brings lot of new features and improvements, with special care to stability, performance, security and flexibility. 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

Top three free VoIP services

Like with emails, some of us prefer to have an independent SIP address, with no relation to current job or location. Being asked several times about free services running Kamailio (OpenSER) or SIP Express Router (SER) – the recently SIP Router project, I am doing a top of my favourite free VoIP providers.

No preference among them, you have to figure out what fits the best for you alone, so I am just listing them in alphabetic order.
