However, it should be noted that the two languages are separate and are not required in an implementation of either language.

Voice Browser Call Control: CCXML Version

You should now see the assigned phone number for your application with PIN code, where applicable. Call Control, session control for telephone calls, has traditionally required interaction with and understanding of telephony APIs which often change from one platform to another.

They exist while the document is loaded. When a session is started due to an incoming call, it has ownership of the event endpoint associated with the new Connection. After the dialog interaction is complete, an asynchronous event is sent to the CCXML session which can use any results returned by the dialog environment to decide what should happen next.

The following requirements are addressed by this specification:. When an ECMAScript variable is submitted to the web server, its value must be first converted into a string before being submitted.

This property is set to either “local” or “remote” and indicates the originator of the connection; for an incoming call, this property is set to “remote”; for an outgoing call, it is set to “local”; For example, the assignment of the originating URI to a variable uri from a Connection instance referenced by the variable cx would be: All Connection instances have a set of properties in common, shown in the following table.

For instance, passing a variable named ‘foo’ with value ” will result in tutoriak ‘session. This flexible event-handling mechanism is essential for many telephony applications. In raw mode it is expected that this attribute will contain a string representation of the fetched content. As far as the VoiceXML application knows the call was just disconnected.

The eventsource has the value of the ” eventsource ” parameter if provided; otherwise eventsource is undefined. If a conference already exists the platform must return the conference identifier of the previously created conference.

Implementations may use additional HTTP parameters specifically to address security. The connection ID for the new connection is returned in the variable ” myConidVar “. If the named conference does not exist, the platform must create a conference object as requested and return the value of the conference identifier to the variable specified in the conferenceid attribute.

Signaling System 7 [ SS7 ]. When a VoiceXML dialog is bridged to a connection with an associated call leg, the ccxl VoiceXML session variables obtain their values from the call leg. Fetched content that could be referenced via a fetchid eg, a CCXML or ECMAScript Document that was fetched yutorial processed mode has a lifetime that is limited to that of the document in which it is fetched.

Will London’s start-ups stay or go? The character string returned is interpreted as a time tutkrial.

These events arrive from outside the program itself – either the underlying telephony platform, or from other sources of events. Figure A and Figure B illustrate the session life-cycle of several different scenarios. Other documents may supersede this document.

A connection is typically shorter than a session. As such, a session cannot bridge a Media Endpoint that it owns to a Media Endpoint that is owned by another session, nor can it establish a bridge between two Media Endpoints owned by another session.

The ECMAScript object returned contains information which may be used by the implementing platform when establishing the outbound connection. In many cases this may be perfectly acceptable and the CCXML application may be able to successfully recover from the error. Platforms MAY choose to implement additional states which may be reflected in the substate property of the Connection object.

Note that the value of the src attribute must not be an ECMAScript expression in order to allow it to be resolved at compile-time. This array MUST be read-only. Implementations may support other event injection processors so long as they do not have the type ” basichttp ” which is reserved for the processor described in this section.

If a platform does not support removal ccx,l tones, it must ignore this attribute. The exact order of operations in this scenario is to play exittone, then unjoin and finally send conference.

Introduction to CCXML, Part IV

However, it is permissible for a CCXML implementation to optimize session changes by “lazy-binding” values as they are accessed or evaluated by a CCXML program, cccml as to minimize processing time. Each connection state constant can be used to index into this array to return the human-readable string corresponding to that tutprial.

When a session terminates, it implicitly detaches from any conferences to which it is still attached. Its focus is user scripting of call handling behavior for incoming calls. Applications may also take actions which change the state of a Connection and which cause other events to be generated.

A failed fetch must return the error. This time interval must be interpreted by the new CCXML session as the maximum time it may wait for the completion of the fetch for ttorial initial document specified by the next attribute.

An implementation platform is not required to use the specified data and certain protocols and network elements may prevent its use. If the value of bridge is ” true ” this will come in with a transfer type of ” bridge tutodial and if the value is ” false ” it will have a type of ” blind “.
