Displaying and Testing the Dial Plan
The dial plan is actually made up of two, separate dial plans. One for IP to ISDN calls, and one for ISDN to IP calls. The
use and administration of these two dial plans is near identical. Refer to the sections below for more information.
To display or modify the IP to ISDN dial plan, go to Home > Dial plan > IP to ISDN. To display or modify the ISDN to
IP dial plan, go to Home > Dial plan > ISDN to IP.

❍ for ISDN to IP calls: a
pattern, a hostname, or
an IP address
meaning that "xxx" will be called if
this rule is invoked.
● Call with the original called
