hi sir,


DID – Direct Inward Dialing (also called DDI in Europe) is a feature offered by telephone companies for use with their customers’ PABX system, whereby the telephone company (telco) allocates a range of numbers associated with one or more phone lines.

Its purpose is to allow a company to assign a personal number to each employee, without requiring a separate phone line for each. That way, telephony traffic can be split up and managed more easily.

DID requires that you purchase an ISDN or Digital line and ask the telephone company to assign a range of numbers. You then need DID capable equipment at your premises which consists of BRI, E1 or T1 cards or gateways.

Hello,


Direct Inward Dialing (DID) is a service of a local phone company (or local exchange carrier) that provides a block of telephone numbers for calling into a company's private branch exchange (PBX) system. Using DID, a company can offer its customers individual phone numbers for each person or workstation within the company without requiring a physical line into the PBX for each possible connection.

For example, a company might rent 100 phone numbers from the phone company that could be called over eight physical telephone lines (these are called "trunk lines"). This would allow up to eight ongoing calls at a time; additional inbound calls would get a busy signal until one of the calls completed or be able to leave a voice mail message. The PBX automatically switches a call for a given phone number to the appropriate workstation in the company. A PBX switchboard operator is not involved.

A DID system can be used for fax and voice mail as well as for live voice connections. Compared to regular PBX service, DID saves the cost of a switchboard operator, calls go through faster, and callers feel they are calling a person rather than a company.

Regards

Hai

DID is a service offered by telephone companies that enables callers to dial directly to an extension on a Private Branch Exchange (PBX) or packet voice system without the assistance of an operator or automated call attendant. This service makes use of DID trunks, which forward only the last three to five digits of a phone number to the PBX or router/gateway. If for example, a company has phones extensions 555-1000 to 555-1999, and a caller dials 555-1234, the local central office (CO) would forward 234 to the PBX or packet voice system. The PBX or packet voice system (Cisco CallManager and IOS router/gateway) would then ring extension 234. This entire process is transparent to the caller.

hai




Short for direct inward dialing (also known as direct dialing inward), a service of an LEC or local phone company that allows an organization to have numerous individual phone numbers for each person or workstation in its PBX system that run off of a small block of dedicated telephone numbers. DID allows the multiple lines to be connected to the PBX all at once without requiring each to have a physical line connecting to the PBX.

Thanks
