Keypad
Some telephone companies’ ISDN systems are using “Keypad
Protocol” for activating/deactivating some supplementary
services, such as external call forwarding. To let the ISDN a/b
adaptor enter “Keypad” mode, you can press:
*00
Then, all the following keys and numbers will be sent out using
“Keypad Protocol”.
Example: If your telephone company give you a keypad
command of *21*number# to activate the external call
forwarding function, you can press:
*00*21*number#
to send out *21*number# with “Keypad Protocol”. After the
keypad command is sent out, all the incoming calls will be
forwarded to the number.
