Call Control Commands

Dial Command: D

Description: The ATD command is used to set a voice, data or fax call. As per GSM 02.30, the dial command also controls supplementary services.

For a data or a fax call, the application sends the following ASCII string to the product (the bearer must be previously selected with the +CBST command):

ATD<nb>

Note: If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not supported.

For a voice call, the application sends the following ASCII string to the product: (the bearer may be selected previously; if not, a default bearer is used).

ATD<nb>; where <nb> is the destination phone number. Emergency calls

The following Emergency Numbers are available without a SIM card: 000, 08, 110, 112, 118, 119, 911 and 999.

The following Emergency Numbers are available with a SIM card: when EF_ECC file is missing from SIM: 112 and 911

when SIM includes an EF_ECC file: 112, 911 and any Emergency Numbers available in the EF_ECC file.

Please note that for an international number, the local international prefix does not need to be set (usually 00) but does need to be replaced by the ‘+’ character.

Example: to set up a voice call to MOXA offices from another country, the AT command is: “ATD+886289191230;”
