 Before an incoming fax is accepted, an LDAP look-up in the user data base checks whether a user/inbox is assigned to the called number. If this is not the case, the call is rejected. The look-up is made by default with all the incoming calls. 
 With the setting of the services in the "DDI Mapping", calls with the feature Voice can be excluded from the look-up.
