Voice over Internet Protocol (VoIP) Direct Inward Dialing (DID)
Direct Inward Dial (DID) is a service that allocates a batch of telephone numbers for connecting to a
company's own PBX.
A VoIP DID service is essentially the same. To access VoIP handsets
or softphones, DID's are connected via a gateway to the trunk of the
public switched telephone network (PSTN) and the organisations own
internal VoIP network. This gateway connects and manages the calls
between the two networks. Calls that originate in the VoIP network will
as look though they have come from one of the assigned DID numbers.
