General
Asterisk is free and open source code to create software PBX server. See http://www.asterisk.org/ for details. The package runs perfectly inside an OpenVZ container. Some users run up to 60 containers with Asterisk deployed for production per single hardware node. Although the easiest way to install Asterisk into a container is to use pre-build package from Linux distribution, occasionally one may need to have a possibility to build it from source tarball available on developer's site.
In order to do so the following remarks are worth reading.
Building Asterisk in a CT
Asterisk PBX server itself is compiled out of the shelf in a container provided that development tools are installed. The functionality of the resulting executable is enough to support simple VoIP telephony.
Debian Dependencies
apt-get install build-essential libncurses-dev
Compiling
wget http://downloads.digium.com/pub/asterisk/releases/asterisk-x.x.xx.tar.gz tar xzf asterisk-x.x.xx.tar.gz cd asterisk-x.x.xx ./configure make make install make samples
The last command is not needed in case you have your own configuration as it installs some sample configuration files. To configure Asterisk itself see, for example, http://downloads.oreilly.com/books/9780596510480.pdf.
MeetMe problem
Unfortunately, one particular module called MeetMe (conferencing tool) will be switched off from compilation. This happens due to external dependency on 'zaptel' package. Zaptel provides support for some hardware cards for FXO/FXS analog telephony marketed by Digium (the company behind Asterisk), and on top of that supplies so called ztdummy kernel module. Ztdummy works like a simple metronome which is required to synchronize multiple sound streams in case of conference call.
If you do not plan to use analog telephone lines, hence don't like in install the hardware, nothing is lost provided you run your HN with 2.6.XX kernel. You just need to play a little trick with Asterisk make system: download zaptel tarball from the same location as Asterisk itself, and copy it's header zaptel.h to location /usr/include/zaptel/zaptel.h in CT where you plan to build Asterisk. This tweaks MeetMe for installation.
HN configuration
Finally you need to make sure that on HN ztdummy kernel module is loaded and the access to /dev/zap/pseudo device file is granted to the container:
modprobe ztdummy vzctl set 240 --devnodes zap/pseudo:rw --save
