Dial Command D
Multi-Tech Systems, Inc. GPRS AT Commands Reference Guide (Document Number S000293J)
Description:
Values:
Chapter 5 – Call Control
The ATD command sets a voice or data call. As per GSM 02.30, the dial command also controls
supplementary services.
Data Calls
For a data call, the application sends the following ASCII string to the product (the bearer must be
previously selected with the +CBST command):
Voice Calls
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).
Emergency Calls
For emergency calls:
International Numbers
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 Multi-Tech offices from another country, the AT command is:
Some countries/regions may have specific numbering rules for their GSM handset numbering.
<nb>
<I>
<mem>
<index>
<name>
The response to the ATD command is one of the following:
Verbose result code Numeric code
OK
CONNECT <speed>
BUSY
NO ANSWER
NO CARRIER
ATD<nb> where <nb> is the destination phone number. Note: If a GPRS PPP session is already
running, the setting of CSD (GSM data call) is not supported.
ATD<nb>; where <nb> is the destination phone number.
These Emergency Numbers are available without a SIM card:
These Emergency Numbers are available with a SIM card:
“ATD+17637853600;”
000, 08, 110, 112, 118, 119, 911 and 999.
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.
Destination phone number
Optional parameter.
<I> means “invocation” (restrict CLI presentation)
<i> means “suppresssion” (allow CLI presentation)
Phonebook (one of SM, LD, MC, ON, ME, RC, MT or SN). A default value can be selected
by using the +CPBS command.
Call number at indicated offset from the phonebook selected by the +CPBS command.
Call number corresponding to given name from the phonebook selected by the +CPBS
command.

Description
if the call succeeds, for voice call only
if the call succeeds, for data calls only, <speed> takes
the value negotiated by the product.
If the called party is already in communication
If no hang up is detected after a fixed network time-out
Call setup failed or remote user release. Use the
AT+CEER command to know the failure cause
