Description
Use this program to set up the system’s DID routing. The DID Translation Table analyzes the DID string
received from the telco and routes it to the corresponding extension. You make separate day and night rout-
ing entries. The DID Translation Table has 100 entries, using 0-9, with * used as a wild card to represent
any digit. The number of digits in your DID entry should match the setting of the
3301-01: Number of DID
Digits (page 834)
.
DID Example: Routing DID Block 400-416
For example, to have DID block 400-416 route to extensions 300-316 during the day and 300 at night
❥ For 3302-01: Incoming DID Digits entry 1, enter 4**.
This entry will route all DID digits in the 400-499 range.
❥ For 3302-01: Day Translation Destination, enter 3**.
The system will strip off the leading digit (4), replace it with 3, and route to extensions 300-399.
❥ For 3302-01: Night Translation Destination, enter 300.
All calls go to extension 300 when the system is in the night mode.
Default Routing
By default, the system uses the last 2 digits of the DID string to route to extensions 300-399 because:
❥ The first entry in the table is *** (i.e., wild card representing any received 3-digit string)
❥ The day routing is 3** (i.e., the last 2 digits of the received string are used to route to the corresponding
extension beginning with 3). For example, a DID block of 400-499 routes to extensions 300-399.
❥ Since the night route is not programmed, night routing follows the day route setting.
Programming Ranges and Exceptions
When programming a range and exceptions into the DID Translation Table, be sure to put the exceptions in
the table first. The following tables show both the correct and incorrect method of setting this up.
Ranges and Exceptions – Correct Configuration
Table Entry Digits Received Day Route Night Route
01 301 303 700
02 302 304 700
03 3** 3**
• Calls to 301 route to 303 in the day and the Automated Attendant at night.
• Calls to 302 route to 304 in the day and the Automated Attendant at night.
• All other calls in the 3xx range route to their respective extensions.
