Dialing Plan Configuring Internal Numbers

Digit Collection Rules

When routing calls, the ShoreTel system follows the digit collection rules specified on the Dialing Plan

edit page in ShoreTel 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 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. Refer to the appendix on emergency 911 operations in the ShoreTel System

Administration Guide for information on how to configure your system for emergency calls.

Defining digit collection for internal numbers

In ShoreTel Director, go to the Dialing Plan edit page under System Parameters and edit the dialing

plan parameters.

Table 21: Digit Collection Rules

Digit Rule

0 By default, 0 is configured in the dialing plan as the

Operator digit. However, 0 can be configured as a trunk

access code, and some other digit can be configured as

Operator.

Digit collection is stopped and the call is routed to the site

operator or to provide trunk access.

# Digit collection is stopped and the call is routed to voice mail

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.

For valid off-system extensions, the call is routed to a trunk.

For invalid extensions, the call is routed to the Backup

Automated Attendant.

This rule does not apply to trunk access codes.
