• To use the ISDN service button on a proprietary telephone, you must assign a flexible
button as the ISDN service button first.
• You can press the CO button instead of entering an ISDN port access code.
• You can receive a confirmation message from ISDN if the network offers such services.
• You can use the ISDN service button after pressing a outside line (CO) access code or a
