The following table describes the digit types contained in the first digit table:
First Digit Type Description
Attendant
The Attendant digit serves two purposes:
• If the caller dials (or transfers a call to) the Attendant digit from a phone
connected to Wave, the PBX connects the caller to a member of the
Attendant hunt group.
• If the caller is connected to AutoAttendant and dials the Attendant digit,
the caller is connected to the operator designated in the AutoAttendant
schedule.
Any digit (but only one) can be configured as the Attendant digit. The default
is zero (0).
If the Attendant digit is changed from the default of zero (0), the Attendant hunt
group pilot number must also be changed, to ensure that the attendant will
receive all calls routed to the attendant.
Caution: It is not recommended that you route inbound calls to
zero because there can be no voice mailbox associated with this
destination.
Extension
The extension digit instructs the PBX to connect calls beginning with these
digits to an extension number (or hunt group pilot number). The number of
digits to collect following an extension digit is defined in the First Digit Table.
The zero (0) digit cannot be configured for extensions.
Default extensions begin with the digit 1 and 5, and are in the range 100-199
and 500-599. Hunt groups use extension numbers to pilot calls to the members
of a hunt group. For example, Wave modems are preconfigured to be in hunt
group 570.
External
An external digit at the beginning of a number instructs the PBX that an
outbound, external call is beginning. You can define the external first digits
(also known as destination access codes) as being one or two digits in length.
Digit collection rules for numbers beginning with external digits are defined in
the First Digit Table.
The default external digit, 9, requires all users to press 9 on their phone dial pad
before dialing any external number to be routed to the public switched
telephone network (PSTN).
Not configured
A digit that is not configured instructs the PBX that calls beginning with these
digits are not valid. If a user dials an unconfigured first digit, the PBX plays a
fast busy tone to indicate that the first digit dialed is invalid.
