Network Call Routing
7 – 2 ShoreTel, Inc.
Define Network Call Routing
Once an external telephone number has been collected, the switching software checks
the number against the user’s call permissions, finds the list of available trunks, and
then makes a routing decision based on several criteria.
Call Permissions
Each dialed number is compared against the user’s call permissions. If the call is denied,
the calling party will be routed to an intercept tone. If the call is allowed, the routing
continues.
Figure 7-1 Call Permissions Edit Page
To define call permissions:
Step 1 Open the Call Permissions edit page (Figure 7-1).
Step 2 Select the Scope. Scope allows you to set a general permission level and
is presented from the most restrictive to the most permissive. The
Restrictions and Permissions listed are applied in addition to the general
scope setting for the Class of Service.
• Internal Only allows calls only to internal extensions and to the
configured emergency number.
• Local Only allows calls only to local or additional local area codes,
as defined on the site edit page. The call permission does not apply
to any of the trunk group area codes.
• National Long Distance also allows calls to long-distance numbers
within the country, as defined on the Site edit page.
• International Long Distance also allows calls to international num-
bers, as defined on the Site edit page.
• All Calls allows calls to any number, including 1900, Operator
Assisted, and Carrier Select numbers, as well as use of Vertical Ser-
vice Codes. This is the default.
Step 3 Enter restriction and permission rules. The Restrictions and
Permissions listed are applied in addition to the general scope setting.
The comma separated restriction expressions are limited to a total of 50
characters.
