Direct Inward Dialing connects you with the world

To put it simply, your DID number first identifies your phone. Then, SIP trunks serve as the link between that identified phone and the Internet. Through the SIP trunk, a DID is connected to the Internet. This DID then allows calls to be forwarded to the right phone.
