[VoiceOps] [External] Re: False 911 calls and old abandoned DID

[Hunter Fuller]

IME it's not so much that the literal digits 9, 1, 1 are pulse dialed,
but some switches are configured so that a bunch of repeated on/off
hook sequences will be treated as an emergency call. I think the idea
is, if someone is severely incapacitated, their attempts to pick up
the phone will be noticed and acted upon.

The losing carrier, either on purpose under the idea of “left in place dial-tone”, or laziness, leaves a copper PSTN line configured as the customer still.  They also don’t maintain their aging copper, so particularly when the cable is wet, short outs and ends up pulse-dialling 911 for them.  Same deal- police response for an unresponsive / hang up 911, and a confused/annoyed customer.  In our case, the PSAPs involved see this so much from the losing carrier every time it rains, we just educate everyone involved, and the PSAP / public safety have to deal with it.  I’m interested in anyone else’s suggestions too.

The CLID shown is NOT one of theirs, but they think it might have been theirs many years ago.  The CNAM on that number is their company name.  Nobody answers the number, and it's with Qwest.  Our logs show no calls to 911 from them.
