Supplementary Service commands are specialized call processing commands used to control carrier
features on the modem such as caller ID, call forwarding, call waiting, 3-way calls, and specialized CDMA
test calls.

Call Forwarding +CCFC

Description: This command allows control of the call forwarding supplementary service, if supported by

the carrier. All calls will be forwarded unconditionally to the phone number specified. The
modem will make a brief call to the CDMA network using an ATD specified prefix number
(country and carrier specific) to setup or cancel call forwarding. An audio tone will be
produced in the audio path to confirm the change of the call forwarding state.

Values:

<number>: The phone number to forward all calls to.
Note 1: Country and carrier specific call forwarding services (e.g. *68, *72, etc.) may also be
available to the host application in addition to the modem provided +CCFC functionality. The
host application can utilize these enhanced services for call forwarding with the modem ATD
command (e.g. ATD*72).
Note 2: If the “FD” facility is enabled, only the entries in the FDN phonebook can be
forwarded.

Syntax:

Command syntax: AT+CCFC= <number>
