Qt Mobility Reference Documentation

Telephony Events

The Qt Telephony Events API enables access to the telephony event services to provide telephony call notification that other applications can use to be notified. Using this API you can get more information about the status of all existing calls.

Note: This API and documentation is a Technology Preview and is still subject to change.

Namespace

The QtMobility APIs are placed into the QtMobility namespace. This is done to facilitate the future migration of Mobility APIs into Qt. See the Quickstart guide for an example on how the namespace impacts on application development.

Overview

The telephony events library provides a set of function for accessing existing calls and their information like. Using this API you are able to queries the current telephony state. e.g. no call, ringing, call in-progress and call on-hold. Signals are provided to inform other application of changes of a call status. e.g. ringing, on-hold, terminating or of a change of the list of the current existing calls. e.g. call is ending. The Application can query call information using this API. e.g. call type, phone number, SIP id, link to the caller contact.

Reference documentation

Main classes

QTelephonyCallInfo

Represents a call including the type, status and other information of the call

QTelephonyCallList

Contains a list of active calls. This object can notify other applications about call changes

Information and Events of Calls

The library provides a number of classes and signals and properties to assist with the access of the calls in a mobile system.

Another application can use this library to get informed about incomming calls, accessing calls information and more of the current system. Basically the library provides an easy access of call information of different OS system (here it is Linux and the DBus system).
