How can the phone number conversion with regular expressions be activated for the called fax number (Called ID) via the tool XpDialingFilter?

In the XPhone Server, under SYSTEM SETTINGS -> UM -> FAX -> GENERAL in the ADVANCED SETTINGS area, enter a new parameter with the name Fax2Mail\ApplyFilterForCalledNumber in the ADVANCED SETTINGS section of the XPhone Server and set the value to 1.  

Accept this setting and save the change on the main page FAX -> GENERAL.

Finally, restart the UM services in the area SYSTEM SETTINGS -> UM -> SERVICES.
