Adding and updating dial plan rules in leased
line mode
This page describes how to add rules to the dial plan when the 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 for the configuration of the dial plan.

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 incoming call 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 is only for IP to ISDN dial plan rules)
this condition matches
when the caller uses the IP address or hostname of the ISDN gateway
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 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".
