Returns all properties for this object. See the

properties section for available properties.

Possible Errors: [service].Error.InvalidArguments
|
|
|
|
void Deflect(string number)
|
|
|
|
Deflects the incoming or waiting call to number given
|
|
in the argument. This method is only valid if the
|
|
call is in "incoming" or "waiting" state and the
|
|
Call Deflection supplementary service is subscribed to.
|
|
|
|
This functionality is generally implemented by using
|
|
the +CHLD=4 * NUMBER command.
|
|
|
|
This method should not be confused with the Transfer()
|
|
method.
|
|
|
|
void Hangup()
|
|
|
|
Hangs up the voice call.
|
|
|
|
For an incoming call, the call is hung up using ATH or
|
|
equivalent. For a waiting call, the remote party is
|
|
notified by using the User Determined User Busy (UDUB)
|
|
condition. This is generally implemented using CHLD=0.
|
|
|
|
Please note that the GSM specification does not allow
|
|
the release of a held call when a waiting call exists,
|
|
or the release of a particular party in a held
|
|
multiparty call.
|
|
|
|
Note that releasing a held call or a particular party
|
|
of a held multiparty call might not be possible on some
|
|
implementations.
|
|
|
|
void Answer()
|
|
|
|
Answers the incoming call. Only valid if the state
|
|
of the call is "incoming."
|
|
|
|
This functionality is generally implemented by ATA
|
|
AT command.
|
|
|
|
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 this 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 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, or the COLP if received by
|
|
the underlying implementation.
|
|
|
|
Please note that COLP may be different from the
|
|
dialed number. A special "withheld" value means the
|
|
remote party refused to provide caller ID and the
|
|
"override category" option was not provisioned for
|
|
the current subscriber.
|
|
|
|
string IncomingLine [readonly, optional]
|
|
|
|
Contains the Called Line Identification information
|
|
returned by the network. This is only available for
|
|
incoming calls and indicates the local subscriber
|
|
number which was dialed by the remote party. This is
|
|
useful for subscribers which have a multiple line
|
|
service with their network provider and would like
|
|
to know what line the call is coming in on.
|
|
|
|
string Name [readonly]
|
|
|
|
Contains the Name Identification information returned
|
|
by the network, if present.
|
|
|
|
boolean Multiparty [readonly]
|
|
|
|
Contains the indication if the voice call is part
|
|
of a multiparty call or not.
|
|
|
|
Notifications if a call becomes part or leaves a
|
|
multipart call are sent.
|
|
|
|
string State [readonly]
|
|
|
|
Contains the state of the current call. The state
|
|
can be one of:
|
|
- "active" - The call is active
|
|
- "held" - The call is on hold
|
|
- "dialing" - The call is being dialed
|
|
- "alerting" - The remote party is being alerted
|
|
- "incoming" - Incoming call in progress
|
|
- "waiting" - Call is waiting
|
|
- "disconnected" - No further use of this object
|
|
is allowed, it will be destroyed shortly
|
|
|
|
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.
|
|
|
|
string Information [readonly, optional]
|
|
|
|
Contains information related to the call for the
|
|
user. Currently this property is set for calls
|
|
initiated by SIM Toolkit applications.
|
|
|
|
byte Icon [readonly, optional]
|
|
|
|
Icon identifier to be used instead of or together
|
|
with the text information.
|
|
|
|
boolean Emergency [readonly]
|
|
|
|
Contains the indication if the voice call is an
|
|
emergency call or not.
