One of the things I really like about PhoneGnome is how you get the best of both worlds with POTS and VoIP. When you place a call using PhoneGnome, a cute voice informs you if the call is local PSTN, on-net with other PhoneGnome users, or long distance. After that, the call goes through just like normal, and there are no extra digits to dial. Very convenient.
Well, we got our first real taste of winter here in Toronto this week, and the power went out yesterday afternoon. It just so happens that this occurred while I was in the middle of a call with my PhoneGnome line. All around me, the lights went out, the modem went quiet, my PC screen dimmed as I went to battery power, Skype went out, and the screens for my IP phones went dark. I'm sure you've all been through this a few times!
That said, my call continued as if nothing happened. Of course, it was a PSTN call - an on-net call to another PhoneGnome user would have died - I think. When the power went out, I heard a short click sound on the line, which must have been the PhoneGnome cutting out, but the call continued as is. Am not sure if PhoneGnome can do a PSTN failover, and automatically port an IP call over to PSTN if the network goes down - would probably have to have a battery backup for that.
Anyhow, I just thought it was great that my call didn't die, which of course, would have been the case if I was using most broadband phone services. Operators like Bell Canada and EarthLink are offering line-powered VoIP to get around this, but the majority do not.
So, for those of you thinking about replacing your POTS with VoIP outright, I'd say think again - unless you have reliable alternatives, namely a cell phone with some battery life on it.
There's another side to this story that vindicates the tech luddite in me. I have never trusted machines of any kind (there's a classic Woody Allen routine about this from his standup days - don't get me started - "So, I gather all of my possessions for a meeting in my living room..."). We have way too many phones in the house, but I always keep an old one around - the kind that doesn't run off electric power - for emergencies or blackouts. Well, I just bought a reconditioned Nortel Vista 100 for this purpose, and that's what's connected to the PhoneGnome. So, while the PhoneGnome did its job, the real reason the call stayed alive was the Vista phone. Score a point for the old guard!
So, the moral of the story for having a bulletproof contingency plan that optimizes the use of POTS and VoIP is to have a line-powered phone with your PhoneGnome.
