Call Control AT Commands

D, Dial Command

This command places a DATA/VOICE call on the current network.

The default call type is a data call (CSD).

There must be an explicit request in order to make a VOICE call.

If a DATA call was originated and answered by the remote side, a "OK" notification is sent to the terminal from the G24-L, and it moves to the online Data state.

For more information about call failure, use the AT+CEER command, described in “+CEER, Extended Error Report” on page 3-213.

Note: If there is an active voice call and the terminal sends another ATD voice call command to the G24-L, the active call is put on hold and the new number is called.
