22.214.171.124 Exception for 911 Emergency Calls
Emergency calls do not require an access code.
The following rules apply only to emergency 911 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.
Although this section focuses on emergency calls made within the United States, the same
rules apply in other countries. See the appendix on emergency 911 operations in the
ShoreTel Administration Guide for information on how to configure your system for
To define digit collection for internal numbers:

The ShoreTel system supports 3-, 4-, and 5-digit extensions.
To change the extension length:
Step 1 Click Increase Extension Length.
Step 2 Specify 4 or 5 digits for the increased length.
After applying your edits, you cannot decrease an extension length. For
example, once it is increased to 4, the minimum is 4.
If your system uses three-digit extensions, ShoreTel recommends that you do
not assign x11 extensions to users.
6.3.2 Configuring External Numbers
The ShoreTel system supports 1-, 2-, and 3-digit trunk access codes. When an access code
is dialed, the system looks for a valid digit in the parameters.
If an invalid number is dialed, the system plays a recording to the calling party.
0 – The digit configured in the
dialing plan as the operator digit.

Any other digit Digit collection continues until a complete extension number is dialed. If the
number is valid, the call is routed to the extension.
• valid off-system extensions – the call is routed to a trunk.
• invalid extensions – the call is routed to the Backup Automated Attendant.
