+CCWA, Call Waiting Command
This command controls the Call Waiting supplementary service, including the settings and the 
queries of the G24 and the network. When the Call Waiting indication is enabled by the G24 and 
there is a waiting call, a +CCWA: indication is sent from the G24 to the terminal. 
Note:
The G24 supports only one of the services at a time: Voice, Data or Fax. Multiparty is a 
voice-only functionality.
A CCWA indication is sent to the terminal only during a voice call-waiting event. A
CCWA indication is not sent for a fax/data call during in a voice session. 
+CCWA Indication
When a call-waiting indication is enabled by the G24 (<n>=1), the following unsolicited 
indication is sent to the terminal from the G24:
+CCWA:<number>,<type>,<class>,[<alpha>][,<CLI validity>]

If <mode>=2 and the 
command succeeds:

The Set command enables/disables the

the network. Activation, deactivation and 
status query are supported.
Note:
When the <mode> parameter is set

parameter is ignored. This means 
that no enable/disable action is 
performed while querying the 
network.
