Multiple Subscriber Numbering
Configuring a Port to Answer Any Number not Configured ElsewhereWhen a port is assigned a specific directory number, it only answers calls dialed to that
number. For example, if you have been assigned the numbers 555-1234, 555-1235, and
555-1236, and you configure Phone Port 1 to answer 555-1234, this phone port won’t try to
answer calls placed to any of the two numbers assigned to you.
One feature of the DIVAT/A is that it allows you assign a port the status of having ‘no
directory number’ (referred to as having been assigned a ‘blank’ DN). A port assigned a blank
DN will answer any calls dialed to numbers not configured elsewhere.
For example, suppose you have four directory numbers assigned to your ISDN line: 555-1111,
555-2222, 555-3333, and 555-444 4. You enter 555-1111 as the primary num ber for phone
port 1 and 555-2222 as its s econdary number. The primar y and secondary num bers for
phone port 2 are left blank.
In this scenario, a call placed to 555-1111 will be sent to phone port 1. A call placed to
555-2222 will also be sent to phone port 1 (as it is the secondary number for that port), and
you will hear a distinctive ring. However, a call placed to either 555-3333 or 555-4444, both of
which have not been configured to any other por ts, will be sent to phone po rt 2.
Note that if Phone Port 2 is disabled (using the checkboxes on the ‘General’ panel), Phone
Port 2 won’t answer the call.
