All the supplementary features are enabled by default. For any features that you don’t want (or have not subscribed to), set the corresponding PaidFeatures bit to "0". Do you want to automatically FORWARD all calls when the line is busy? If so, you need to use the CALL FORWARD ON BUSY feature. First, make sure CallFeatures and PaidFeatures bit 1 for PHONE1 and/or bit 17 for PHONE2 are set to "1" (enabled). Second, assuming you are using the default U.S. style CallCmd parameter value, pick up the telephone handset, enter #74 #, and then hang up. This will automatically forward all the calls to the designated phone number if the line is busy. Please make a note that if the power goes off or the unit is upgraded, this CALL FORWARD ON BUSY feature will automatically reset and you will have to re-enable it again through the same procedure.
