◆ HandleCurrentCalls()

void cuttlefish::CallService::HandleCurrentCalls ( const Client & client )

AT+CLCC Returns list of current calls of MT. If command succeeds but no calls are available, no information response is sent to TE.

command Possible response(s) AT+CLCC [+CLCC: <ccid1>,<dir>,<stat>,<mode>,<mpty> [,<number>,<type>[,<alpha>[,<priority> [,<CLI validity>]]]][<CR><LF> +CLCC: <ccid2>,<dir>,<stat>,<mode>,<mpty> [,<number>,<type>[,<alpha>[,<priority>[,<CLI validity>]]]] +CME ERROR: <err>

<ccidx>: integer type. This number can be used in +CHLD command operations. Value range is from 1 to N. N, the maximum number of simultaneous call control processes is implementation specific. <dir>: integer type 0 mobile originated (MO) call 1 mobile terminated (MT) call <stat>: integer type (state of the call) 0 active 1 held 2 dialing (MO call) 3 alerting (MO call) 4 incoming (MT call) 5 waiting (MT call) <mode>: integer type (bearer/teleservice) 0 voice 1 data 2 fax 3 voice followed by data, voice mode 4 alternating voice/data, voice mode 5 alternating voice/fax, voice mode 6 voice followed by data, data mode 7 alternating voice/data, data mode 8 alternating voice/fax, fax mode 9 unknown <mpty>: integer type 0 call is not one of multiparty (conference) call parties 1 call is one of multiparty (conference) call parties <number>: string type phone number in format specified by <type>. <type>: type of address octet in integer format

◆ HandleDial()

void cuttlefish::CallService::HandleDial	(	const Client &	client,
		const std::string &	command
	)

Normal dial: ATDnumber[clir]; Emergency dial: ATDnumber@[category],#[clir];

◆ HandleEmergencyMode()

void cuttlefish::CallService::HandleEmergencyMode	(	const Client &	client,
		const std::string &	command
	)

AT+WSOS

Command Possible response(s) +WSOS=[<n>] +CME ERROR: <err> +WSOS? +WSOS: <n> +CME ERROR: <err>

<n>: integer type 0 enter emergency mode 1 exit emergency mode

see RIL_REQUEST_EXIT_EMERGENCY_CALLBACK_MODE RIL_UNSOL_ENTER_EMERGENCY_CALLBACK_MODE RIL_UNSOL_EXIT_EMERGENCY_CALLBACK_MODE in RIL

◆ HandleHangup()

void cuttlefish::CallService::HandleHangup	(	const Client &	client,
		const std::string &	command
	)

AT+CHLD This command allows the control of the following call related services: 1) a call can be temporarily disconnected from the MT but the connection is retained by the network; 2) multiparty conversation (conference calls); 3) the served subscriber who has two calls (one held and the other either active or alerting) can connect the other parties and release the served subscriber's own connection.

Calls can be put on hold, recovered, released, added to conversation, and transferred similarly.

command Possible response(s) +CHLD=<n> +CME ERROR: <err>

+CHLD=? +CHLD: (list of supported <n>s) e.g. +CHLD: (0,1,1x,2,2x,3,4)

◆ HandleMute()

void cuttlefish::CallService::HandleMute	(	const Client &	client,
		const std::string &	command
	)

AT+CMUT This command is used to enable and disable the uplink voice muting during a voice call. Read command returns the current value of <n>.

Command Possible response(s) +CMUT=[<n>] +CME ERROR: <err> +CMUT? +CMUT: <n> +CME ERROR: <err>

<n>: integer type 0 mute off 1 mute on

◆ HandleRejectCall()

void cuttlefish::CallService::HandleRejectCall ( const Client & client )

◆ HandleRemoteCall()

void cuttlefish::CallService::HandleRemoteCall	(	const Client &	client,
		const std::string &	command
	)

AT+REMOTECALL=<dir>,<stat>,<mode>,<mpty>,<number>,<num_type> This command allows to dial a remote voice call with another cuttlefish emulator. If request is successful, the remote emulator can simulate hold on, hang up, reject and so on.

e.g. AT+REMOTECALL=4,0,0,6521,129

<stat>: integer type (state of the call) 0 active 1 held 2 dialing (MO call) 3 alerting (MO call) 4 incoming (MT call) 5 waiting (MT call) <mode>: integer type 0 voice 1 data 2 fax 3 voice followed by data, voice mode 4 alternating voice/data, voice mode 5 alternating voice/fax, voice mode 6 voice followed by data, data mode 7 alternating voice/data, data mode 8 alternating voice/fax, fax mode 9 unknown <mpty>: integer type 0 call is not one of multiparty (conference) call parties 1 call is one of multiparty (conference) call parties <number>: string here maybe remote port <num_type>: type of address octet in integer format

Note: reason should be added to indicate why hang up. Since not realizing RIL_LAST_CALL_FAIL_CAUSE, delay to be implemented.

◆ HandleSendDtmf()

void cuttlefish::CallService::HandleSendDtmf	(	const Client &	client,
		const std::string &	command
	)

AT+VTS This command transmits DTMF, after a successful call connection. Setting Command is used to send one or more ASCII characters which make MSC (Mobile Switching Center) send DTMF tone to remote User.

Command Possible response(s) AT+VTS=<dtmf>[,<duration>] +CME ERROR: <err>

<dtmf> A single ASCII character in the set { 0 -9, #, *, A – D}. <duration> Refer to duration value range of +VTD command
