Doug Mohney of HDVoice News recently noted that The Telecommunications Industry Association (TIA) has issued a series of new standards documents in reference to wideband audio over analog connections. These new standards specify how HDVoice may be implemented with regard to analog telephone, speakerphones, headsets and related terminal equipment.
Yes, that is exactly what it sounds like…formal specifications for delivering wideband voice over traditional FXO/FXS connections.
This is more than just a curiosity, and could be very valuable to the widespread adoption of HDVoice outside of the mobile space.
Let’s consider the case of the Cable Companies. It’s been noted that their “Digital Voice” customers are well positioned to benefit from HDVoice. Cable companies have gained many residential and SMB voice lines in recent years, enough to cast Comcast as the third largest Telco in the US.

While I ordered the DoorBell Fone back in August the fact of our extreme Houston summer kept me from completing the installation. The buried wire run out to our gate was broken and there was just no way I was going to bury a new wire in 100+ degree heat. This past weekend I was able to find the time and temperature to complete the installation.
The largest task was to completely replace the wiring from the central closet in our house out to the gate. I replaced the old-skool solid copper pair with a length of Cat-5 cable. Using Cat-5 is a bit of future-proofing. It means that I can change to a POE-powered network device at the gate without replacing the cable again.
For the moment I’m using only one pair from the Cat-5 wiring, connecting the DoorBell Fone remote unit to the controller in the wiring closet. The total cable length is about 80 feet.

A short while ago I briefed you on my years-long search and utterly frustrating search for the perfect, affordable, SIP/IP-based door phone, preferably with video. Having set aside that lofty goal, I resigned myself to retain primarily the “affordable” aspect of the prior set of specifications, which lead me to look for an analog door phone.
There are many analog door phones available from companies like 2N, Adtran, Avaya, Bogen, NEC, Panasonic, Valcom & Viking, just to name a few. For my project, based upon some advice from friends, I settled upon Door Bell Fon as a suitable choice.
As a vendor I selected Home Controls since they had inventory, a good price, and seemed to have some experience with the product. My order included the DP28C control module, a DP38 NBZF door station and DP38 BXFS surface mount box. The total cost was right around $300.

I’ve recently been reflecting upon my history as an Asterisk user and the evolution of my preference for embedded systems (aka appliance) approach to Asterisk servers.
The path that I’ve followed is probably typical of a lot of people in many ways. Perhaps by sharing my experience I can help some people avoid some of the problems that I have faced, and understand how I arrived at my personal definition of an “Asterisk Appliance.”

Its many advantages not withstanding I was driven to use VOIP for other reasons. Understanding my motivation will perhaps help you to also understand why I’ve gone in some of the directions outlined elsewhere on this site.
I despise AT&T…
…and if at all possible I will never spend another dollar with them.
In the mid-1990s my wife had local phone service from SBC and long distance from AT&T. When we started dating AT&T was pursuing her over what they believed was a bad debt. The matter was eventually tracked to an internal accounting error. However, in their zeal to pursue her they badgered us for weeks with threatening phone calls. Their threats included variety of possible actions, some of which were in fact illegal. If only I had recorded those calls!
