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 c alled number and also includes
calls where the called number is not known or unavailable. G enerally, this kind of rule
should be used towards the bottom of the dial plan list to m atch 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 Cisco TelePresence ISDN Gatewa y.
o Called number matches:
To match a specific number, enter that specific number.
Example: to match calls to "001234", type 001234. The c ondition will match that
and only that number.
Use S to match * (asterisk) and use P to match # (pound/has h). Examples: to
match calls to "*234", type S234; to match calls to "#0987 ", type P0987
To match a more general number, use the wildcard charac ter, D. This matches
any digit as well as # and *.
Example: to match any number that starts with "55" follow ed by exactly two more
digits, type 55DD. This condition will match "5 500", "5523", "5555", "5599", etc.
but not "55" or "55233".
For more general matching, you may use one of the three repe at 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 possibl y more".
"D*" means "match any digit, any number of times". D m atches 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.
