Portech GSM Gateway: Prior Art

A number of people in the VOIP user community have deployed this device already, some have even documented their efforts. Such prior art will no doubt help me get mine working also. Here are their notes: The VOIP wiki: http://www.voip-info.org/wiki/view/Setup+MV-370+GSM+Gateway+with+Asterisk…

The snom m3: Range Limitations & DECT Extender vs Roaming

Two weeks ago my wife told me that the small snom m3 handsets are not working as well as they should. To be specific, when she’s in the front bedroom the call quality is not good. I was out of town at the time but eventually got around to looking into the matter.

It’s is a simple matter of signal propogation. That bedroom location is the furthest possible point from the base radio, which was in my office.

snom m3 Revisited

Some reaction to the snom review is starting to trickle in. One reader, Lonnie Abelbeck, noted that he had an issue with daylight savings time on his snom m3. He sent the following message;

Michael,

I read your review of the SNOM m3 in SmallNetBuilder, excellent review. I recently purchased the same m3 setup you have, very pleased as well.

Next VOIP Project: SIP-GSM Gateway

The other day I called my cellular carrier, T-Mobile. They tell me that I can convert my plan to a “family plan” and add another phone. Further, it’d be ok if I provided the phone myself, perhaps an old GSM phone that I haven’t used in a while. I have an old Razr sitting a drawer somewhere. But I have other plans for the hardware.

I have a huge number of minutes on my plan as I often use my cell for tech support work that can go for hours. Then this week the US cellular market is rocked by new offers of “unlimited” minutes for $99/mo. That’s what I presently pay for my 2500 minute plan. Might have to change that plan soon. This just makes me think that I really should go forward with a plan to add a SIP-GSM gateway to my Astlinux setup.
