Reading the T32/38G template, BLP fields 11 to 16 represent the 6 line keys. The problem is there is a limited number of options on the 3cx Phone Provisioning screen. Defining lines is not one of them. Is there a way to add options? Does the provisioning screen just "update" entries in the MACID.CFG file? or will all entries be re-written if we change one of the other BLF keys? Is there a planned improvement to the provisioning options?
