[cisco-voip] School Building VoIP 911

[Erik Potteiger]

Hello,

I am thinking about installing a VG224 for about 15 lines at a public building.  I have UCM 6.1 and a Cisco 2801 SRST with 2 FXO ports both FXO ports are connected to POTS lines and all 911 calls are routed out the POTS lines.  I also have a fire alarm that will be connected to 2 POTS lines.  All components are on a UPS that can handle a power outage of 10 minutes.  After 10 minutes all phones would be dead except for the fire alarm system.  I am concerned about 911 during a power outage.  If all the phones are dead in a public building during a power outage is this illegal?  I am not concerned about safety almost everyone in the building carries a cell phone.  I am thinking keeping one POTS line at the front desk.  Any suggestions or information about 911 laws.

Thank you,
Erik
