I recently needed to install Freeswitch for a singular reason: to register to another server when a SIP client registered to it. (What I call "register on register"). As I went, I decided to document the process of installing and configuring. This server is running Debian 5.0.2, and is a virtual container on top of another Debian lenny install, utilizing the OpenVZ virtualization infrastructure. Note: During my first install, the container only had 1 GB of space. About half of that gets taken up by Debian. For whatever reason, that turned out to not be enough.
