Adding and updating dial plan rules in leased line mode This page describes how to add rules to the dial plan w hen the Cisco TelePresence ISDN Gateway is in
leased line mode. It also tells you how to update rules.
When you use the ISDN Gateway in leased line mode, the options on the dial plan are different to those
in ‘non leased line mode’. This is because as there is no D -channel, no number is sent over the leased
line call; this necessarily affects the options available f or the configuration of the dial plan.
Note that you may also find it helpful to refer to Exam ple dial plan rules.
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 incoming call : this condition matches any inc oming call 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 is only for IP to ISDN dial plan rules) this condition matches
when the caller uses the IP address or hostname of the ISDN G ateway
o Called number matches: (this is only for IP to ISDN dial plan rules)
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/h ash). 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.
