Zeeek’s First Impressions Of The Allnet 7960 IAX/SIP Phone
Over at VUC Zeeek has blogged about his first impressions of the sample Allnet 7960 that he's had for a few days.

I must admit that I'm more than a little surprised a what people read around here. The single most popular article is the one I wrote back in January 2006 about Building An Embedded Asterisk Server Using Astlinux On a…
What is IAX2? And Why Does It Matter To Me?
Randy (aka Zeeek or Randulo), founder of the VOIP Users Conference, was able to get his hands on a sample of the Allnet 7960 today and sent his initial thoughts on the device to the conference mailing list. This prompted another reader to pose the simple question, “Why does this matter?” (or something similar) More specifically, why does IAX2 matter in the light of a larger trends toward widespread SIP and IMS?
It’s a good question. So here’s my response.

The weekly VOIP Users Conference calls have often mentioned the Chinese made IAX phones, including both their strengths and weaknesses. Jared Smith posted a brief but positive comment on the Asterisk Users mailing list today with respect to a new…
Successful VOIP Over DSL, Part 5: Power Considerations
One of the great things about the traditional PSTN is that it keeps working when the power goes out. I’ve repeatedly read others recommending that people sustain traditional POTS service at least in part because of this fact. Their theory being that VOIP service isn’t sustained during a power outage. But this need not be the case given just a little forethought.
Prior to migrating to Asterisk we had been using a Panasonic KX-TG4000 KSU (seen left). This phone system has four FXO interfaces for analog lines.
It also featured a built-in battery backup so our phones stayed up through power outages. In migrating to VOIP within our home and office I felt it necessary to strive for this kind of reliability. It has certainly made my wife happier.

The Asterisk open source Voice over IP (VoIP) PBX is usually set up on a standalone PC. But Michael Graves shows how the combination of a special Asterisk distribution and a single board computer can provide a compact, quiet and low-power alternative.
Introduction
Astlinux is a bundled distribution of the Asterisk open source iPBX private branch exchange (PBX) software and a Linux operating system. Originally developed by Mark Spencer at Digium, Asterisk is the leading open source software in the telephony/VoIP space. Asterisk excels at combining traditional TDM telephony capability – provided through hardware from Digium and others – with VOIPservices. These include call routing, media gateway, media server and SIP signaling capabilities.
The Asterisk user community has been growing tremendously over the past two years, especially since the v1.0 release in the fall of 2004. With that growth has come the development of new distributions that bundle suites of software tools, to ease the setup and administration of a new Asterisk system. Asterisk@Home and Xorcom Rapid are both fine examples of this sort of activity.
Astlinux was developed by Kristian Kielhofner, and intended to go in a fundamentally different direction. Astlinux provides an Asterisk installation on a Linux distribution that has been built from scratch and optimized for small format hardware platforms – it takes what is essentially an embedded systems approach to Linux and Asterisk. In this article, I’ll show you how to build an VoIP PBX using Astlinux and a Soekris Net4801 single board computer (SBC).
