+CCWA - Call Waiting SELINT 2
Note: the response to the query command is in the format:
+CCWA: <status>,<class1>[<CR><LF>
+CCWA: <status>,<class2>[ … ]]
where
<status> represents the status of the service:
0 - inactive
1 - active
<classn> - same as <class>
Note: the unsolicited result code enabled by parameter <n> is in the
format::
+CCWA: <number>,<type>,<class>,[<alpha>][,<cli_validity>]
where:
<number> - string type phone number of calling address in format
specified by <type>
<type> - type of address in integer format
<class> - see before
<alpha> - string type; alphanumeric representation of <number>
corresponding to the entry found in phonebook; used character
set should be the one selected with +CSCS.
<cli_validity>
0 - CLI valid
1 - CLI has been withheld by the originator
2 - CLI is not available due to interworking problems or limitations of
originating network
Note: if parameter <cmd> is omitted then network is not interrogated.
Note: in the query command the class parameter must not be issued.
Note: the difference between call waiting report disabling (AT+CCWA =
0,1,7) and call waiting service disabling (AT+CCWA = 0,0,7) is that in the
first case the call waiting indication is sent to the device by network but this
last one does not report it to the DTE; instead in the second case the call
waiting indication is not generated by the network. Hence the device
results busy to the third party in the 2
nd case while in the 1 st case a ringing
indication is sent to the third party.
Note: The command AT+CCWA=1,0 has no effect a non sense and must
not be issued..
AT+CCWA? Read command reports the current value of the parameter <n>.
AT+CCWA=? Test command reports the supported values for the parameter <n>.
