Multiple Subscriber Numbering

Configuring a Port to Answer Any Number not Configured Elsewhere

When 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 DIVA T/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 555-4444. You enter 555-1111 as the primary number for phone port 1 and 555-2222 as its secondary number. The primary and secondary numbers 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 ports, will be sent to phone port 2.

Note that if Phone Port 2 is disabled (using the checkboxes on the ‘General’ panel), Phone Port 2 won’t answer the call.

You can disable phone ports entirely by unchecking these boxes
