[asterisk-users] life safety system and VOIP

[Jeff LaCoursiere]

I think the BAT SIGNAL is the answer.

POTS lines have their issues as well - how many times did we redial to get 
into our ISP's in the mid nineties?  I have trouble believing the fire 
code actually spells out that dedicated POTS lines must be used.

Regradless I think another "hold harmless" just made it into my service 
contract.
