Will be implementing an emergency responder for a new customer. They are in one building on multiple floors. All 911 calls will go out to the same PSAP. Everyone will have a DID number.
Should the individula DID numbers be used for the ELIN's or would they still need to assign DID's to use as ELIN's for each ERL?
Seems like the individual's DID would provide call back details without needing special ELIN numbers but then ERL would be needed for each ELIN.
Am I understanding this correctly?
What would be recommendation for a one site / DID shop?
