What is Direct In-Dial (DID)?

Direct In Dial is sometimes referred to as a 100 number in-dial range. You can allocate a Direct Indial number to an individual, a department or a particular program within your business. This number can be dialled directly from the outside world, reducing the number of telephone calls that have to be answered by a central receptionist or switchboard operator. You could, for example, you can allocate a Direct Indial number to a specific advertisement to enable operators to respond with an appropriate greeting.

When customers call your Direct Indial number, your ISDN 10/20/30 service will automatically search for a free line to receive the call. A Direct Indial number range may span a number of ISDN services in order to provide sufficient lines for both incoming and outgoing calls.

On outgoing calls, your Direct Indial extension number can be passed to the network, if your equipment supports this function. The network then uses your Direct Indial extension number to present to services you have called with calling number display. The network may also use your Direct Indial extension number for extension level billing. See What is extension level billing? for more details.

If your equipment does not support passing of your Direct Indial extension number to the network, then the network will use your group directory number for both presentation and billing purposes. In-dial ranges are always consecutive blocks of 100 numbers. They always start with 00 as the last two digits and end with 99 as the last two digits.

Direct In-Dial (DID) is available on all ISDN services supplied by IF Telecom. This includes Telstra ISDN 10/20/30, Optus and AAPT.
