Creating routes
Pattern
Usage
(pattern)
Causes the pattern in parentheses and the matching substring to be stored in a
variable ($1, $2, ….) for subsequent substitution into the outgoing calling/called
number or from/to URI.
For example, the pattern 508(\d*) matches 5082711847 and sets the variable $1 =
2711847.
Use multiple enclosed patterns to store multiple matching substrings in different
variables.
For example, the pattern sip:(.*)@(.*) matches sip:
[email protected] and sets the variables $1 = 5082711847 and
$2 = gateway.dialogic.com.
Letters, digits,
Match what they represent.
and other
For example, the pattern 847 matches the area code in the number 8475558900
characters
and also matches the last three digits in [email protected].

on page 68.
; (semicolon)
Indicates the end of the outgoing routing pattern and the start of call routing
