How can number conversion with regular expressions also be activated for the called fax number (Called ID) via the XpDialingFilter tool?
In XPhone Server under SETTINGS -> UM -> FAX -> GENERAL in the ADVANCED SETTINGS area, add a new parameter via the ADD button with the name
and set the value to 1.
Apply this setting and then save the change on the FAX -> GENERAL main page.
Finally, restart the UM services in the SETTINGS -> UM -> SERVICES section.
