Affordable Cordless Mobility In The Home Office

Obi-Hai-S12-KX-TSC11-trio-300sqEarlier this week Bill left a comment asking for a recommendation about a phone and cordless headset combination. His requirements seem quite sensible and he expresses some frustration with his existing gear. His situation seems one that could be very common, so I thought it worth highlighting before trying to make some recommendations.

Here’s his comment in full:

Sorry for bringing back an old thread – but am hoping you might have some advice. I am a home office worker & spend a lot of time on the phone with colleagues & customers. I’m not using a speakerphone – but I am currently using a Plantronics S12 headset & Panasonic KX-TSC11 phone connected to an OBi110 for both POTS and VOIP capability. The audio quality is just “ok”, and the S12 creates an annoying hum when I raise the microphone volume.

I would like to upgrade to a better (binaural, over the head, no little buds sticking into my ear) headset, preferably DECT to enable me to stand and move about a bit while on calls (is DECT a safe bet for call quality & consistency?). Also it would be convenient to have a built-in answering machine if the quality is very good.

The *paramount* concern is that my voice quality sound loud & clear to callers. I would also like the devices to be wideband-capable (realizing this only affects VOIP).

Do you have any suggestions for a phone/headset combination for this scenario? Thanks very much in advance!

Bill’s existing gear bears examination. With just a few minutes of Googling I found that the Panasonic KX-TSC11 is a very basic analog phone. They’re available for around $45 and have only one analog POTS connection. Panasonic refers to it as an “Integrated Telephone System” which seems a bit puzzling to me. It’s a bit like calling a pen a “fully manual correspondence creation system.” It’s an entry-level analog phone.

Win A Gigaset DX800A with HDVoice

Gigaset-DX800A-250Our friends at Gigaset are continuing to promote their wares to a broad audience, this time with a contest offering their DX800A desk phone. The DX800A has been available in Europe for a year or more, but has yet to be released in North America. It’s release is anticipated at the coming CES show in January 2012.

The Gigaset DX800A is a desk phone that incorporates a DECT base, supporting a number of cordless handsets. It’s HDVoice capable supporting G.722 audio over SIP.

It also supports the use of wideband audio over its built-in Bluetooth radio. I tried it using my Plantronics Voyager Pro UC while at CES last year.

Barbarians At The Gate: The Doorphone Series

Ok, perhaps “Barbarians” is not the correct term, especially since we like both our current Fedex and UPS delivery drivers. This list summarizes the project that added an intercom to our front gate.

To be able to communicate with the delivery person at the gate has been a tremendous convenience. In fact, in the past few weeks I’ve not made the far-too-familiar trek down to the local Fedex Office location to pickup a missed delivery.

An Analog Phone For Our Front Gate: Done Deal!

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.

OT: Gigaset Product Promotion In Hollywood

Gigaset is pushing onward with promotion of their brand to the North American market, this time getting involved with the Emmy Awards. Tony Stankus sent a link to their Facebook page where they have posted a photo gallery of a number of TV actors holding various Gigaset wares.

That’s cute, and good for the company profile. However, the curious part is that in some of the photos you see them holding the a little wearable hands-free badge or the handset of one of the DX series desk phones. I wasn’t aware that these items, rumored some time ago, had even made it to these shores. This could be a sign of good things to come in the near future.

HDVoice: On The Cheap & Analog RJ-11 Style

HDVoice RJ-11 Wall Plate A short while back I addressed the question of how DECT & CAT-iq may foster the broad deployment of HDVoice. At that time I described one possible scenario where carriers would deploy customer premises equipment (CPE) with an on-board cordless base station. Although a frontrunner, and the basis of Comcast’s (decidedly non-HD) HomePoint service, this is not the only approach afoot. There’s another possibility arising that involves conveying HDVoice over a plain old analog RJ-11 connection.

At first glance HDVoice and analog lines would certainly seem to be mutually exclusive. The common wisdom is that wideband telephony requires the use of an all-IP call path. This is in fact a generalization, and not absolutely true.

Firstly, it has long been possible to pass wideband audio, in the form of G.722 encoded media, over the PSTN by way of ISDN connections. Also known as BRI interfaces, an ISDN connection supports  up to two 64 kbps channels (bearer channels) and one D channel for the purposes of call setup & teardown signaling. High-quality voice using G.722 was one of the selling points of ISDN in the 1980s.
