the remaining fields.

a. In the Pattern Name field, enter a descriptive name for the route

pattern.

b. In the Grp No field, enter the trunk group number configured in

Configuring SIP trunk groups on page 319.

c. In the FRL field, enter the Facility Restriction Level that allows access to

this trunk, 0 being least restrictive.

Configuring private numbering

1. Enter the change private-numbering 0 command to define the calling party

number to be sent

2. Add an entry for the

Configuring SIP trunk groups on page 319.

In the example shown below, all calls originating from a 3-digit extension beginning with 2 and

routed across any trunk group (shown by the Trk Grp(s) setting being blank) will result in a 3-

digit calling number. The calling party number will be in the SIP From header.
