DETAILED STEPS
Examples
The following example shows how to create dial-plan pattern 1 for extension numbers 101 to 199 with
the telephone prefix starting with 4085550. If the following example is set, the router will recognize that
4085550144 matches dial-plan pattern 1. It will use the extension-length keyword to extract the last
three digits of the number 144 and present this as the caller ID for the incoming call.
call-manager-fallback
dialplan-pattern 1 40855501.. extension-length 3 no-reg
Command or Action Purpose
Step 1
call-manager-fallback
Example:
Router(config)# call-manager-fallback
Enters call-manager-fallback configuration mode.
Step 2
dialplan-pattern tag pattern extension-length
length [extension-pattern extension-pattern ]
[no-reg]
Example:
Router(config-cm-fallback)# dialplan-pattern 1
4085550100 extension-length 3 extension-pattern
4..
Note This example maps all extension numbers 4xx
to the PSTN number 40855501xx, so that
extension 412 corresponds to 4085550112.
Creates a global prefix that can be used to expand the
abbreviated extension numbers into fully qualified E.164
numbers
• tag—Dial-plan string tag used before a 10-digit
telephone number. The tag number is from 1 to 5.
• pattern—Dial-plan pattern, such as the area code, the
prefix, and the first one or two digits of the extension
number, plus wildcard markers or dots (.) for the
remainder of the extension number digits.
• extension-length—Sets the number of extension
digits.
• length—The number of extension digits. The range is
from 1 to 32.
• extension-pattern—(Optional) Sets an extension
number’s leading digit pattern when it is different from
the E.164 telephone number’s leading digits defined in
the pattern argument.
• extension-pattern—(Optional) The extension
number’s leading digit pattern. Consists of one or more
digits and wildcard markers or dots (.). For example,
5.. would include extension 500 to 599; 5... would
include 5000 to 5999.
• no-reg—(Optional) Prevents the E.164 numbers in the
dial peer from registering with the gatekeeper.
Step 3
exit
Example:
Router(config-cm-fallback)# exit
Exits call-manager-fallback configuration mode.
