CDMA VoiceCallManager hierarchy [experimental]
===============================
Service org.ofono
Interface org.ofono.cdma.VoiceCallManager
Object path [variable prefix]/{modem0,modem1,...}
Methods dict GetProperties()
Returns properties for the VoiceCallManager Interface.
See the properties section for available properties.
void Dial(string number)
Initiates a new outgoing call. This is usually
implemented using the ATD AT command.
Possible Errors: [service].Error.InProgress
[service].Error.InvalidArguments
[service].Error.InvalidFormat
[service].Error.NotImplemented
[service].Error.Failed
void Hangup()
Hangup all active calls.
Possible Errors: [service].Error.InProgress
[service].Error.NotImplemented
[service].Error.Failed
void Answer()
Answer the incoming call. This only affects the
incoming call.
void SendFlash(string flash_string)
Sends the flash string to the network.
void SendTones(string tones)
Sends the DTMF tones to the network. The tones have
a fixed duration. Tones can be one of: '0' - '9',
'*', '#', 'A', 'B', 'C', 'D'. The last four are
typically not used in normal circumstances.
void SetProperty(string property, variant value)
Changes the value of the specified property. Only
properties that are listed as readwrite are
changeable. On success a PropertyChanged signal
will be emitted.
Possible Errors: [service].Error.InvalidArguments
[service].Error.DoesNotExist
Signals PropertyChanged(string property, variant value)
Signal is emitted whenever a property has changed.
The new value is passed as the signal argument.
DisconnectReason(string reason)
This signal is emitted when the modem manager can
provide extra information about why the call was
released. The possible reason values are:
"local" - The call was release due to local
user action
"remote" - Remote party released the call
"network" - Network released the call, most
likely due to low signal or
other network failure
Not all implementations are able to provide this
information, so applications should treat the emission
of this signal as optional. This signal will be
emitted before the PropertyChanged signal.
Properties string State [readonly]
Contains the state of the current call. The state
can be one of:
- "active" - The call is active
- "dialing" - The call is being dialed
- "alerting" - The remote party is being alerted
- "incoming" - Incoming call in progress
- "disconnected" - No call is connected
boolean CallWaiting [readonly]
Contains whether a call is waiting.
string CallWaitingNumber [readonly, optional]
Contains the call waiting number.
string ToneDuration [readwrite]
Contains the length of the DTMF tone duration. The
currently supported values are:
"short",
"long"
string LineIdentification [readonly]
Contains the Line Identification information returned
by the network, if present. For incoming calls this is
effectively the CLIP. For outgoing calls this attribute
will hold the dialed number.
Please note that after sending flash this property
will be empty.
string StartTime [readonly, optional]
Contains the starting time of the call. The time is
stamped when the call enters the "active" state.
Client applications can use this to infer somewhat
reliable call duration information.
Please note that after sending Flash, there will not be
any StartTime property change for the Flash
string/number.
