Product news

The very first SIP-compatible software I installed myself was SER, Sip Express Router, from, a spinoff from the Fokus research institute in Berlin. During the years I have worked with SER and OpenSER/Kamailio, I’ve become friends with many of the developers and have contributed with documentation and training. The team gathers world leading SIP experts and developers, so it’s a joy to meet them and brainstorm and share experiences. In almost all my installations and platforms, a SIP proxy is at the core of the real time multimedia platform. My choice has always been SER/OpenSER/Kamailio.

Starting as a SIP proxy, moving on as an extensible SIP server

Sip Express Router started as an Open Source SIP Proxy. Today we see Kamailio, based on the common core, as an extensible SIP server. With an embedded presence server, http support and interfaces to python and lua for scripting, it’s a platform that can handle many different roles in a large-scale SIP architecture. IPv4 and IPv6 support from the beginning, security integrated and a very active development team. Everything you need to build a standard-compliant cool network for your organization’s real-time communication. 10 years of success.

Jubilee September 2nd, 2011 where it all started

The 3rd of September marks 10 years since the start. Reason to celebrate, don’t you think?


We will celebrate on Friday, September 2nd and into the night. FhG Fokus Research Institute hosts a one-day conference session with all the core people. If you have any interest in SIP and these platforms, make sure you will be there.

The event is organized with sponsorships from FhG Fokus Institute, Asipto, Amooma and TeamForrest. At the same time local events will be organized in Barcelona, Spain and Vienna, Austria.  Read the agenda and register today!

Garret Smith writes some thoughtful words about WiFi phones in his blog:

Infonetics Research released a report that showed WiFi ip phone sales increase 60% in 2007, with 682,000 units were sold worldwide. The report cited “increased vendor support” as the primary reason for the growth. 


While some people seem to like WiFi phones, they aren’t for the faint at heart, especially if your aren’t technically savvy. My advice, if you want to go wireless, is to pickup a DECT based solution. A little more expensive, but it works…for everyone. 

I still haven’t met a WiFi SIP phone I liked and used more than a couple of days…
