This command is based on GSM 07.07 [2] subclause 7.11, and allows control of the Iridium Call

Waiting supplementary service similar to GSM 02.83 [6]. Activation, deactivation and status
query are supported. Parameter <n> is used to disable/enable the presentation of the
unsolicited result code to the DTE when the Call Waiting service is enabled.

Command is abortable in the cases when the network is interrogated. The interaction of this
command with other commands based on other GSM supplementary services is described in the
GSM standard.

Defined values

<n> (sets/shows the result code presentation status in the A3LA-R):

0

disable unsolicited result presentation

1

enable unsolicited result presentation

On a DTE-DCE command, <n> will set the result code presentation status in the A3LA-R,

regardless of the value of any <mode> parameter.

<mode> (when <mode> parameter is not given, network is not interrogated):

0

disable Call Waiting service for specified class(es)

1

enable Call Waiting service for specified class(es)

2

query status of Call Waiting service for specified class(es)

<classx> is a sum of integers each representing a class of information:

1

voice

2

data

4

fax

This parameter defaults to 7, equal to all classes, but the A3LA-R/RM/RGS only supports
Voice Call Waiting so this is illegal. Therefore in practice the DTE must supply <classx>=1.

<status>:

0

Call Waiting service not active for specified Class

1

Call Waiting service active for specified Class

<number>: quoted string type phone number of calling address in format specified by <type>

<type>:

type of address octet in integer format (refer GSM 04.08 [7] subclause
10.5.4.7);default 145 when dialing string is international number, otherwise 129.

If the network rejects a request to activate/deactivate the Call Waiting service due to it not
being provisioned (or for other reasons), the reported CME ERROR code will be 133 “requested

service option not subscribed”. This is strictly speaking a GPRS-related code (GSM 07.07 [2]
subclause 9.2.2), but is the most informative choice in this case.

Informative examples:

The status of only the Voice class can be queried:

AT+CCWA=1,2,1

If the command is successful, the A3LA-R might return (after contacting the network):
