I am currently evaluating a Moxa UC7408 for one of my customers.  The UC7408 is a small fanless industrial computer that runs Linux or Windows CE.  This article provides a basic overview of this unit and a review of some of the UC7408 features and the Linux distribution Moxa provides.

There are many options when selecting a VoIP provider to terminate your Asterisk PBX.  One of the most important factors in this selection is the quality of the internet connection between your PBX and the VoIP provider.  The route between you and your VoIP provider is one of the most important considerations when selecting a provider.  This article details a simple method for evaluating this connection using Asterisk.

In our quest to implement an Asterisk PBX in our office, we are evaluating several VOIP (Voice Over IP) providers.  VOIP provides several benefits over traditional phone lines including:

• low cost (typically around $0.02 per minute)
• available in pre-paid plans
• can support concurrent concurrent calls on the same number 
  

However, implementing VOIP successfully is not trivial.  You must have a reliable internet connection and we have found you must implement some type of Quality of Service (QoS) in the router. The first problem I ran into was calls sounded great to me, but people I called mentioned the calls sometimes sounded garbled to them.  This article discusses the diagnosis of this problem and how to implement QoS in a Linksys router to fix this issue.
