International virtual phone numbers with cloud PBX can connect multiple sites and remote locations and employees to one network without any extra call charges, It allows you to create a virtual presence where you have no physical presence. 

Direct Inward Dialing (Estonia DID) is a telephone service that permits a phone number to ring through legitimately to a particular phone at a business instead of setting off to a menu or a queue and expecting to dial an extension. A phone number that is utilized like this is frequently called a “DID” (and numerous numbers are called “DIDs”).

Using Estonia  DID number, a company can offer its employees individual phone numbers for each person or workstation within the company without requiring a physical line into the PBX for each possible connection.

Estonia DID numbers can be used for fax and voice.

DID is also offered by telephone companies for the use with their customers’ PBX system, whereby the telephone company (telco) allocates a range of telephone numbers allocated with one or more phone lines. 

DID allows a company to allocate a personal number to each employee, without requiring a separate physical phone line for each to connect to the PBX. This way, telephony traffic can be split up and managed more easily.

DID works likewise for VoIP communications. To permit PSTN users to directly reach VoIP users, DID numbers are assigned to a gateway. The gateway connects the PSTN (public switched telephone network) to the VoIP network, routing and translating calls between the two networks for the VoIP user. Calls from the PSTN will be coordinated to the VoIP user who holds the corresponding DID number.

Compared to regular PBX service with PSTN, DID with IP- PBX saves the cost of a switchboard operator, calls go faster and callers feel they are calling a person rather than a company.
