Below are the Frequently asked questions about telobal services, Please read before asking your question:
WHAT IS A DID NUMBER?
In practical terms, a DID (Direct Inward Dialing) Number or a Virtual Number (also called a DDI in Europe) is a local telephone number in a selected country or city. The calls made to these numbers are then forwarded by DIDWW to Voice over IP (VoIP) using SIP, H.323 or IAX protocols, or to a PSTN (Plain Old Telephone System) device such as a regular or mobile telephone anywhere in the world.
Typically, a DID Number is used to provide local telephone numbers for customers on a worldwide basis, or to provide access from regular telephones to non-PSTN destinations such as VoIP.
