Background Information on PSTN Outward Number Masks
The outbound number mask is a regular expression that:
 Selects incoming phone numbers based on specific criteria
 Outputs all or part of the phone number as the dialed number in the
outbound PSTN call
The mask as a whole selects incoming phone numbers. But the Media Gateway
outputs only the portion of the mask that is within parentheses.
For example, examine the default PSTN outbound number mask:
([\+]?[-\*\#\d]+)
The first part of the expression, [\+]?, specifies that the incoming number may
either begin with + or not. The next part of the expression, [-\*\#\d]+, specifies
that the incoming number can include one or more of any of the following
values in any order:
 -
 *
 #
 A digit (0 to 9)
For example, all of these incoming phone numbers match this regular expres-
sion:
 123-456-7890
 [phone]
 12-34-5678
 #12-34-5678
 *
Because the parentheses surround the entire expression, the Media Gateway
outputs the phone number exactly as it receives the number.
