The dialed number string also allows a wildcard pattern for the last two digits. For example, 99X (X can be 0-9), or 99XX(XX can be 00 -99).

X is the only supported wildcard character and it represents the alphanumeric/alphabets/numbers which are supported by the dialed number string.

The wild card feature is controlled by the router registry key DNWildCardEnabled. If the registry key is not set, the routing does not happen correctly.

The router registry key DNWildCardEnabled is disabled by default. To enable it:

• On the router machine, run regedit to open the Registry Editor.
• Go to the location Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cisco Systems, Inc.\ICM\XXX\RouterA\Router\CurrentVersion\Configuration\Global. XXX is the instance name.
• Double-click DNWildCardEnabled
• In the Value data field, delete 0, and type 1.

Note - You only need to configure this on Router A as it will auto sync this registry update to the B side. Check and see!
