Outgoing private calls routing
When you set up routing for private calls, the route is set to Private. Refer to “Configuring call
routing” on page 331 .
How the system identifies the call depends on the type of trunk chosen for the route. Refer to the
table below.
Setting up public network dialing
The Public network settings allows you to enter DN lengths for the networks the callers are
allowed to dial, including special numbers such as 411 and 911.
The public DN lengths table is used for all PRI calls except for those routes that use service type
Private or service type Tie with DN Type specified as Private. This table allows the Business
Communications Manager to determine the length of a DN, based on the initial digits dialed.
A set of default Public DN lengths is included with the default template. In most cases it is not
necessary to change the default values.
About the Public DN lengths table
In the public DN lengths table:
• You can define up to 30 entries.
• Each entry consists of a DN prefix string (1 to 10 digits) and a length value (two digits, 1 - 25).
• Several entries are predefined in the North America profile. These defaults can handle most
regions in North America without the need for additional programming. If required, you can
remove or modify these entries.
• The table always contains one default entry. You cannot remove this entry. You can only
modify the length parameter associated with this entry. The default entry specifies the length
of any dialing string that does not match one of the other table entries.
