Call Center World 2015

Call Center World 2015 takes place in Berlin, Germany, during February 24-26. I will meet some customers and visit the show for one day. If anyone wants to meet at the event or for some drinks in the evening at a nice place in Berlin, contact me.

Kamailio has a lot of features that can be useful in such deployments, including a module for music on hold queuing. Features such as load balancing or least cost routing can help scaling as well as saving costs on outbound calls.

Kamailio v4.1.8 Released

The Kamailio SIP Server v4.1.8  stable version  is released. This is a minor release including fixes in code and documentation since v4.1.8 – configuration file and database compatibility is preserved within 4.1.x series. We recommend all users of 4.1.x versions to upgrade to this new version – no configuration changes are needed.
Note that branch 4.1 is the previous stable branch. The latest stable branch is 4.2, at this time with v4.2.2 being released out of it. The project is officially maintaining the last two stable branches, these are 4.2 and 4.1. Therefore an alternative is to upgrade to latest 4.2.x – be aware that you may need to change the configuration file from 4.1.x to 4.2.x.
