Description
Choose a name that describes the type of rule you are creating,
e.g. "Local" or "Long Distance".
The Pattern field gives you the ability to use basic pattern
matching to differentiate calls and route them accordingly. For
instance, if a number begins with _9256, and is followed by 7 or
more digits, that would define a call within the state of Alabama. If
a call began with _9 followed by 7 digits, it would be a local call
that probably doesn't require a long distance charge. Instead of
adding a rule for every extension or phone number you call,
specify the pattern in this rule similar to the example. All patterns
begin with the underscore "_" character. There are special
characters which can be used in patterns:
• X - Any digit from 0-9
• Z - Any digit from 1-9
• N - Any digit from 2-9
• [1,2,3,6-9] - Any digit within the brackets, in this instance 1, 2, 3,
6, 7, 8, 9.
• . - The period is the wildcard which will match anything
remaining. For example, _9011. matches anything starting with
9011.
• ! - The exclamation point is a wildcard which causes the
matching process to complete as soon as it can determine that
no other matches are possible.
Calls matching the pattern specified will be routed to the
destination specified in Destination if this checkbox is selected.
Specify a destination, such as voicemail or main menu, for calls to
be routed to when the Send to Local Destination checkbox is
selected.
