Electronic Alarms and Home Security Devices - alarm reporting over t-mobile @home voip

Has anyone had success sending signals over this service or any other voip? Currently I have a safewatch 3000 connected to the phone as primary and a 7845gsm as backup. With the @home distributed to my patch panel I have line seizure, but cannot get the panel to report sucessfully. In the interim, I have deleted the dialer and have the gsm programmed as primary. Anybody have any ideas before I upgrade to 7845i ($208) or the vista 21ip gsm kit ($245)

I like the idea of the 21ip, but not sure how I will put this thing online since our cs doesn't support it yet.

Any ideas are appreciated

I've had pretty consistent success with the telephone adapter that Cox uses to emulate phone lines. Contact ID and SIA are a bit fussier about the compression issue than the more primitive formats.

I still have a slight twitch over relying on these for emergency communications. (The local AHJs in most of North Central Florida will not accept such derived phone systems for Fire Service or Elevator emergency phones).

The problem is that you have to have battery backup at the local adapter, battery backup at the central switch where it connects into POTS lines, and I've seen both get hosed for _days_ at a shot.

Of course, I've seen ATT/Bellsouth glitch out for hours at a shot without any admission of error, either...

I too have never had a problem with the cable co's digital phone service.

I have heard that 4X2 works better over VoIP, but my panel will not send this format.

I agree, I would not rely on it for the only communication, but I am ok with it when used in conjunction with a cellular backup.

I have thought about getting a UPS, but with cell backup, I don't know if it is needed.

I will probally go with the 7845iGSM. I have a CAT5 cable going to my panel location so it should be pretty simple.

It's funny, all of this came to light after being given a company blackberry. I already had a Blackberry from T-Mobile, and my wife has a line, too. It seemed like a good idea to transfer my cell line to my home phone and save my number and money to boot. Now, I just have to make the necesarry alarm changes.:cool:

Just an update, I tried sending signals in ademco 4+2 l/s, 4+2 radionics and 4+2 ademco express. None of these formats reported at all. Looks like I will be purchasing a 7845i-GSM

I try to stay on top of this issue, and, even now, digital "phone" and VOIP are still a bit of a crapshoot where alarms are concerned. Many of the brands are finally getting true IP communicators into the stream, but the adaption of the receivers by the central station companies is still a little spotty.
