Enable/Disable automatic dialing from phone book on DTR activation
(ON/OFF transition).
If automatic dialing is enabled and the DTR signal line switches from OFF to
ON, the ME attempts to set up an outgoing call to the number stored at the
first index of the "ME" phone book, or using telephone number “112” in case
of an emergency call.
When a call setup starts all other active or held calls are dismissed.
Repeated DTR activation events while call setup is in progress or during a
call established this way are ignored. Also, all DTR activation events during
multiplex mode are discarded.
To enable auto dialing for data and voice calls after ME´s power-on it is
necessary to disable PIN authorization with the command
AT+CLCK=”SC”,0,<pin>. To prevent misuse of this unprotected SIM card it
is recommended to limit its network facilities. For details refer to the “FD” pa-
rameter of “AT+CLCK Facility lock”, pg. 101.
