Hi,

Just a brainstorm here.....has anyone had any experience using a voipfone number/extention on a monitored security system??

I'm in the business of installing alarms and was wondering if anyone has ever tried this, it just seems cheaper than to run and rent a new BT line for the sole purpose of connecting the alarm system to the monitoring service (or directly to a key holder as in some cases)

Another quirk to this could be that as a failsafe, in a power failiure, the connection to the internet and server systems is generally backed b y a UPS which maintains the power supply for a few hours or so. The alarms I install also have a 4 hour battery backup sothat in the event of a power failiure the connection to the voipfone line would be maintained sothat a power loss message could be sent out.

Any thoughts any1???

Don't these systems do some non-voice communication stuff down the line too?

Or is it just a regular voice call?

If the former, then there's no guarantee that these signals would make it over the VoIP link intact.

Depends on the speed of the transmition, Sky boxes do not work but some people have said some of the fax machines that run at a slower data rate do work! (14.4 Kbps for example)

Although i have never tried it so can't be 100% on that, just what i have read. Even then it was not very reliable!

As pointed out above if it just plays a voice mesage via a voice dialer then there really shouldn't be a problem.

Do you know speed the alarm system sends it's data?
