Chapter 8 – Supplementary
Services Commands
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 prCCFC 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.
