This guide is a reference on how to create a RedHat Enterprise Linux v6 template for OpenVZ.
There are other ways and variations on how one can go about this. The method I will present here is the way I do it. In this case I used the recompiled from source distribution known as Scientific Linux. This guide should work equally well for any distribution including Redhat, CentOS etc. It also works for v5 with a few minor changes or omissions which should be obvious. This guide was used with the 32bit distribution.

With the recent introduction of patch 3 for Aastra XML scripts 2.2.1 we now have scripts that work on Asterisk 1.6 as well as 1.4. The installation procedure has also been greatly simplified.

A short guide on how to use High Definition VoIP on Asterisk and FreePBX.
What is it
HD VoIP in the Asterisk world involves selecting the g722 codec for VoIP calls. g722 is known as a wideband codec as opposed to g711 which is narrowband. The nice thing about it is that it does not require any more bandwidth than g711. Both require 64kbit/s each way for a 2-way conversation.

This install procedure can be used in a generic OpenVZ or Virtuozzo environment or inside an all in one OpenVZ installer+GUI product such as Proxmox VE. It is the procedure used to create servers for our Asterisk hosting service. I am not sure how relevant it would be for Xen. This guide covers the installation INSIDE an already created OpenVZ/Virtuozzo container (VPS sans Operating System) which would then become a functioning Virtual Private Server (VPS). I will not be covering the OpenVZ host setup or iptables or zaptel/dahdi setup inside or outside the OpenVZ environment.

External SIP or in other words SIP through firewalls and routers or more accurately SIP traversal through Network Address Translation (NAT) is arguably one of if not the most common problem people face. SIP is notorious for this. This little article is my attempt to provide a simple no nonsense method of finding and fixing these problems. Ideally before they ever happen. To keep it simple I will assume everything on the PBX itself is configured correctly.
