Planning and Installation Guide 6 – 3
For maximum usability, map extension numbers to the final digits of your DID (if
DID is used).
NOTE Extensions cannot begin with “911” (911, 911x, or 911xx).
Digit Collection Rules
When routing calls, the ShoreTel 6.1 system follows the digit collection rules specified
on the Dialing Plan edit page in ShoreWare Director.
For the first digit collected, specific rules are in effect.
Exception for 911 Emergency Calls
Emergency calls do not require an access code.
The following rules apply only to 911
1
calls:
• If “911” is dialed, the switch routes the call to a 911-capable trunk group
associated with the caller’s User Group.
• Before switching the emergency call, the switch invokes a brief timeout for
insurance against accidental 911 calls. If any digit is entered during the timeout,
the switch routes the call to the Backup Automated Attendant.
Please see the appendix on emergency 911 operations in the ShoreTel 6 Administration
Guide for information on how to configure your system for emergency calls.
To define digit collection for internal numbers:
• In ShoreWare Director, go to the Dialing Plan edit page under System Parameters
and edit the dialing plan parameters. See the ShoreTel 6 Administration Guide for a
description of the parameters on this page.
Changing Extension Length
The ShoreTel 6.1 system supports 3-, 4-, and 5-digit extensions.
To change the extension length:

number is valid, the call is routed to the extension.
• If the extension is a valid off system extension, the call is routed to a trunk.
• If the extension is invalid, the call is routed to the Backup Automated
Attendant.
Note Rule does not apply to trunk access codes.
