DID Number
Length The number of digits needed to match a DID (Direct Inward Dialing)
number. The range is from 2 - 16.
Each extension can be assigned a DID number. A DID number does
not have a fixed length. For example, suppose the DID number
length is 4 and the extension DID number is 2522999. Depending
on the service contract with the Central Office (CO), the DID trunk
can send all 7 digits (2522999) or just the last 4 digits (2999). If the
DID Number Length option is set to 4, the system always tries to
match the last 4 digits received to the last 4 digits of a DID number,
regardless of what is received.
Note: To accommodate future growth and minimize disturbance, it
is recommended that the length of the DID numbers assigned to an
extension be greater than or equal to this DID Number Length.
Dialed Digit
Translator This feature is capable of intercepting and manipulating a dialed
digit string before it is sent out for outbound call processing.
To set up a dialed digit translator entry, check the Enable checkbox
and click the Setup key. This opens a dialog box where you can
select First Digit Translator or Extension Dialed Digit
Translator.
This feature supersedes the first digit assignment of the system
number plan. When configured, any extension user can dial a single
DTMF digit that will be translated to any internal or external
number. After digit manipulation, the translated digits go through
the system number plan to find the internal or external target. For
example, you can configure “*” to call an internal workgroup to
report an urgent situation.
Typical applications are:
• One-digit emergency dialing
• One-digit dialing to branch or headquarters over PSTN or VoIP
• One-digit dialing to activate a feature code
