org.jvoicexml.xml.vxml.Transfer

All Implemented Interfaces:

VoiceXmlNode, XmlNode, org.w3c.dom.Node

public final class Transfer
extends AbstractXmlNode

Transfer the caller to another destination.

The <transfer> element directs the interpreter to connect the caller to another entity (e.g. telephone line or another voice application). During the transfer operation, the current interpreter session is suspended.

Field Detail

TAG_NAME

public static final java.lang.String TAG_NAME

Name of the tag.

See Also:

Constant Field Values

ATTRIBUTE_NAME

public static final java.lang.String ATTRIBUTE_NAME

Stores the outcome of a bridge transfer attempt. In the case of a blind transfer, this variable is undefined.

See Also:

Constant Field Values

ATTRIBUTE_EXPR

public static final java.lang.String ATTRIBUTE_EXPR

The initial value of the form item variable; default is ECMAScript undefined. If initialized to a value, then the form item will not be visited unless the form item variable is cleared.

See Also:

Constant Field Values

ATTRIBUTE_COND

public static final java.lang.String ATTRIBUTE_COND

An expression that must evaluate to true in order for the form item to be visited.

See Also:

Constant Field Values

ATTRIBUTE_DEST

public static final java.lang.String ATTRIBUTE_DEST

The URI of the destination (telephone, IP telephony address). Platforms must support the tel: URL syntax described in RFC2806 and may support other URI-based addressing schemes.

See Also:

Constant Field Values

ATTRIBUTE_DESTEXPR

public static final java.lang.String ATTRIBUTE_DESTEXPR

An ECMAScript expression yielding the URI of the destination.

See Also:

Constant Field Values

ATTRIBUTE_TYPE

public static final java.lang.String ATTRIBUTE_TYPE

The type of transfer. The value can be "bridge", "blind", or "consultation".

See Also:

Constant Field Values

ATTRIBUTE_BRIDGE

public static final java.lang.String ATTRIBUTE_BRIDGE

Determines whether the platform remains in the connection with the caller and callee.

bridge="true"

Bridge transfer. The platform adds the callee to the connection. Document interpretation suspends until the transferred call terminates. The platform remains in the connection for the duration of the transferred call; listening during transfer is controlled by any included <grammar>s.

If the caller disconnects by going onhook or if the network disconnects the caller, the platform throws a connection.disconnect.hangup event.

If the connection is released for any other reason, that outcome is reported in the name attribute (see the following table).

bridge="false"

Blind transfer (default). The platform redirects the caller to the callee without remaining in the connection, and does not monitor the outcome.

The platform throws a connection.disconnect.transfer immediately, regardless of whether the transfer was successful or not.

See Also:

Constant Field Values

ATTRIBUTE_CONNECTTIMEOUT

public static final java.lang.String ATTRIBUTE_CONNECTTIMEOUT

The time to wait while trying to connect the call before returning the noanswer condition. The value is a Time Designation. Only applies if bridge is true. Default is platform specific.

See Also:

Constant Field Values

ATTRIBUTE_MAXTIME

public static final java.lang.String ATTRIBUTE_MAXTIME

The time that the call is allowed to last, or 0s if no limit is imposed. The value is a Time Designation. Only applies if bridge is true. Default is 0s.

See Also:

Constant Field Values

ATTRIBUTE_TRANSFERAUDIO

public static final java.lang.String ATTRIBUTE_TRANSFERAUDIO

The URI of audio source to play while the transfer attempt is in progress (before far-end answer).

See Also:
