Field
Description
Dial Plan
Dial plan script for this trunk.
NOTE: The trunk SUA will also apply the Trunk Dial Plan on the number
before sending out INVITE to the ITSP. This Trunk Dial Plan typically is
redundant since the trunk should trust the number sent by the Line SUA. By
default the trunk dial plan allows any non-empty number:
([*#0-9A-D][*#0-
9A-D].)
