[VoiceOps] False 911 calls and old abandoned DID

[Mary Lou Carey]

I did miss that piece....thanks for clarifying! Maybe you can find out 
what SPID is associated with the TN in NPAC and notify that carrier so 
they can address it internally. I'm sure the PSAP would appreciate the 
help in making sure calls from unassigned numbers don't clog up their 
network.
