What is the difference between stacked and exclusive numbers ​

WARNING

Applies to VoipNow 3 and higher!

Stacked numbers ​

The Direct Inward Dialing (DID) numbers defined as stacked are available to all the Service Providers in the system without being specifically assigned.

If a Service Provider assigns a DID number to one of their owned accounts, the number will no longer be available to other Service providers.

Exclusive numbers ​

The system administrator assigns the Direct Inward Dialing numbers defined as exclusive to the Service Providers that will be using them.
