CER - DiD Utilization for PSAP Callback

Can a customer use their established DIDs for PSAP callback rather than buying new DIDs. Do you know if that's possible with CER? Can CER just pass through the real DID to the PSAP, or do you have to get new DIDs to assign to each ERL?

Re: CER - DiD Utilization for PSAP Callback

To set up the ELIN numbers, you must first obtain direct inward dial (DID) numbers from your service provider. Because you must pay for each number, you might want to limit the number of DIDs you obtain to two or three per ERL. The DIDs must be unique for each ERL.

Do the DIDs need to be in sequential order?
