Adding dial plan rules
To add a dial plan rule:
1. Go to
Dial Plan
. If you want to add an
o
IP to ISDN rule, use the
IP to ISDN
page.
o
ISDN to IP rule, use the
ISDN to IP
page.
2. Click
Add rule
.
3. Type a name for the rule.
4. For
Condition
choose one of:
o
Match any called number
: this condition matches any called number and also includes
calls where the called number is not known or unavailable. Generally, this kind of rule
should be used towards the bottom of the dial plan list to match numbers not recognized
by more specific rules higher up.
o
No called number
: this condition matches when the called number is not known or
unavailable for ISDN calls. For IP calls, this condition matches when the caller uses the
IP address or hostname of the ISDN gateway
o
Called number matches
:
To match a specific number, enter that specific number.
Example: to match calls to "001234", type
001234
. The condition will match that
and only that number.
Use S to match * (asterisk) and use P to match # (pound/hash). Examples: to
match calls to "*234", type
S234
; to match calls to "#0987", type
P0987
To match a more general number, use the wildcard character,
D
. This matches
any digit as well as # and *.
Example: to match any number that starts with "55" followed by exactly two more
digits, type
55DD
. This condition will match "5500", "5523", "5555", "5599", etc.
but not "55" or "55233".
For more general matching, you may use one of the three repeat characters.
These modify the character immediately before, whether it is a specific digit or
the wildcard character. The repeat characters are:
?
match once or zero times.
+
match once or more.
*
match zero or more times.
For example, "5+" means " match at least one 5, but possibly more".
"D*" means "match any digit, any number of times". D matches any digit as well
as # and *.
Example: to match any number that starts with "01", has any amount of digits in
the middle, and ends with "5", type
01 D* 5
.
To include any of the incoming called digits in the outgoing called number,
enclose each substitution group in a set of parentheses. Note that if you wish to
