This is a little off topic, but just so very interesting that I had to post it. Reading this mornings news I discovered that C-SPAN interviewed Marty Cooper, the inventor of the cell phone. You can see the entire 30…
It’s been a while since I installed the little Portech MV-370 GSM gateway. It sits in the office IT stack and does what it does. When I’m traveling it lets me call home using my unlimited mobile-to-mobile minutes. It also backs up our IP-based home & office phones. If both the Comcast Cable modem and Covad DSL are out the we can route calls out via T-Mobile.
The Gigaset cordless phones support enough accounts that this is easy, just add #6 to the number to specify dial using the GSM trunk. The GSM gateway is the 6th account on the Gigasets. We don’t even need a local Asterisk system to make it possible.
Remembering back to the installation of the GSM gateway, I converted my T-Mobile account from an individual plan to a family plan, with the gateway device becoming the second line on the account. I dropped my number of minutes but the monthly carrying cost was the same. It seems like a good idea since the use of mobile-to-mobile minutes to call home was going to reduce my need for minutes in the end.
Paul O'Flaherty released this curious little vidcast that makes a good point.
For months I've been waiting for a new cell phone. There seems to be a dearth of suitable candidates available. So I'm going to try running a reader poll. I had been very interested in the Nokia N97 which has…
This is just brilliant! A great slice of the state of cellular, voice & mobile internet in a very approachable form. Fact filled and funny, too!
A short while ago Nir Simionovich noted an interesting new piece of hardware on his blog. It’s the embodiment of a novel approach to adding GSM based cellular trunks to an Asterisk server. As opposed to a freestanding external SIP-to-GSM gateway that I installed last year, someone has devised a new TDM-GSM module that emulates that FXO daughter card on a Digium TDM400P card. According to the companies web site two modules can be installed to a TDM400P card, providing Asterisk with two GSM trunks. No drivers are required beyond those loaded for the TDM400P.
