Well it finally happened. During the recent weather frenzy here in New Jersey, one of our customers lost power. Some time ago they converted their phones to VoIP. With no battery backup. Annnnnd...they had a fire. Couldn't understand why the fire department didn't show up :slaphead:. It's not clear how this is particular case is going to play out, but we know that more and more customers are going to be moving away from POTS. It's clear in fact that in may locations POTS may simply not be available under any circumstances. We still have in our central station contracts a clause that says that the fire alarm dialer has to be hooked to a POTS line, but I wonder what alternatives others are exploring. And yes, I know about IPDACT's and such, and when the power is out the central station will know when the IPDACT disappears, but if a fire occurs the customer is SOL. We're thinking radios for backup. Other ideas?
