PBX access code
If you’re connected to a switchboard, you might need to enter an access code 
(e.g. 9) before you dial a number. Your BT8500 can store an access code which 
is automatically dialled before each number. We cannot guarantee that all the 
BT8500 features will work when connected to a PBX.

PBX code menu and delete all the digits by selecting Clear, then select Save.
