An Unexepected Benefit Of My SIP-to-Cellular Gateway
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.
There’s a little leather-covered box that sits at the back of my desk. It’s the recipient of small items of technology that for some reason I can’t really use but also can’t stand to just throw away. It held until recently an impressive selection of Bluetooth cordless headsets.
It’s been a while since I paid any attention to OnSIP. Since they are my primary ITSP this very fact is probably “a good thing.” It means that we haven’t had any issues. However, they have been making a few changes in their service. These changes bear closer examination.
