network when a new GSM registration takes place.
2.
OFF - This means that the corresponding Call Forward mode is disabled and this setting is sent to the GSM
network when a new GSM registration takes place.
3.
Not Set - This means that there is no change to the current Call Forwarding mode and nothing is sent to
the GSM network when a new GSM registration takes place. This is useful by leaving the current Call
Forward mode unchanged.
