Gigaset One: Bluetooth-Based Cell-to-PSTN Interface

A couple of weeks ago friend Tony up at Gigaset promised to send me a couple of the newer Gigaset DECT handsets that they’ve started to sell in the US. The box arrived and true to his promise there are a couple of handsets..but this is not about them. Left with a little space in the box Tony threw in a Gigaset One Bluetooth interface device. It’s proven to be a curious and interesting little device.

Let me be completely clear about this….it’s not often that manufacturers just send me stuff (disclosure statement). After almost 600 posts to this blog I’ve managed forge a few good relationships with manufacturers, but in most cases I simply buy whatever hardware I truly need, and that’s what I get to write about.

An Unexepected Benefit Of My SIP-to-Cellular Gateway

blackberry-bold-9700-2It’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.

Open Source Hardware Where Art Thou?

audiocodes-mediapack-114VoIP Supply’s Garrett Smith has an interesting post the other day. Actually, we can cross reference a couple of posts to follow his line of thinking. Firstly, he offers some advice on selecting an analog gateway in a post titled, “Four Keys To A Successful Voip Gateway Purchase.” It’s a good basic overview on VoIP gateways for the beginner.

I’ve made my thoughts on gateway/ATA devices well known in the past (here, here and here). I see them as relics of a prior era of VoIP, and to be avoided if at all possible. However, some people feel that they are truly necessary. Whatever floats your boat.

A little later on over at VoIP Supply’s VoIP Insider Blog Garrett poses the question, “Where Are The Open Source VoIP Gateways?” That is a fine question and one the deserves an answer. It also needs to be broken down a bit to get to a clear answer.

Peace In VoIPland: Bridging the SIP & Skype Kingdoms

opensky_logoLast year a number of people lead a charge to get Skype to open their network to greater interoperability with the open standards-based VoIP world. Gizmo5’s Michael Robertson, ever the instigator, was perhaps the most vocal of the group. Various others weighed in with opinions, including such notables as Dan York, Andy Abramson, Phil Wolff, Alec Saunder & others. At the time it sounded not unlike Mr Reagan telling Mr Gorbachev to “tear down these walls.”

Then word came out of Astricon that Digium had forged a partnership with Skype. The result would be “Skype For Asterisk,” a channel module allowing the integration of Skype into the leading open source IP-PBX platform. A great cheer went up all around VoIP-land. There was much rejoicing.
