However, when you attempt to set a call forwarding option which is not provisioned or not yet subscribed to,
the setting will not take effect regardless of the response returned. The responses in these cases vary with
the network (for example "OK", "Operation not allowed", "Operation not supported" etc.). To make sure check
the call forwarding status with
<mode>
=2.
• Some networks may choose to have certain call forwarding condtions permanently enabled (e.g. forwarding
to a mailbox if the mobile is not reachable). In this case, erasure or deactivation of call forwarding for these
conditions will not be successful, even if the CCFC request is answered with response "OK".
• The command has been implemented with the full set of <class> parameters according to GSM 07.07. For
actual applicability of SS "call forwarding" to a specific service or service group (a specific
<class>
value)
please consult table A.1 of GSM 02.04.
• There is currently no release of GSM standard "GSM 02.04", in which the "Call Forwarding" Supplementary
Service is defined as applicable to SMS services.
Example
Please note that when you configure or query call forwarding without specifying any classes, the settings will
refer to classes 1, 2 and 4 only (=default). The handling of classes is equivalent to
AT+CLCK
.
• To register the destination number for unconditional call forwarding (CFU):
The destination number will be registered for voice, data and fax services (default
<class>
7).
In most networks, the registration will also cause call forwarding to be activated for these
<class>
values.
• To query the status of CFU without specifying
<class>
:
• To deactivate CFU without specifying
<class>
:
To check whether CFU was successfully deactivated (note that the destination number remains registered in
the network when you disable CFU):
• To erase the registered CFU destination number:
Now, when you check the status, no destination number will be indicated:
