Cisco CUCM Wildcards

In this post we will lean some of Cisco CUCM wildcards. They are used in route patterns and translation patterns.  The most famous ones are described below.

the X wildcard

The X wildcard replaces only one character. For example, 587X pattern has 10 combinations: from 5870 to 5879.

The @ wildcard

The @ wildcard is a macro. Each time you use it, CUCM replaces it with a number of route patterns that correspond to the numbering plan you chose. For example, if you choose to use the North American numbering plan with the @ wildcard, CUCM will internally generate some US route patterns such as the following:
So let’s say you have two gateways that you want to use for egress calls. You assign the first gateway to the @ route pattern and the second to the XXXXXXX route pattern. The call will be routed through the first gateway, because there is the route pattern [2-9]XXXXXX, which is a better match than XXXXXXX.

The brackets [] wildcard

With a bracketed pattern, you can have any digit from the available options. for example, [165]223 pattern has the following possibilities:

  • 1223
  • 6223
  • 5223

The negated brackets wildcard

the X wildcard

The X wildcard replaces only one character

The + wildcard

This wildcard means “one or more of the preceding character”. For example, 444[165]+ pattern can have the following possibilities: 4441, 444111, 44466,…
