[Previous: Qt Pim Module] [Qt Extended Modules] [Next: Qt UI Module]
The Qt Telephony module provides telephony related components which are common to AT and VoIP related telephony. This module is based on Base Module.
The following configure line can be used to build the Base and Telephony module:
./configure -modules telephony -device xyz
Qt Extended provides a unified API for telephony. This means that for instance VoIP services can be accessed via the same classes as GSM/3G services and therefore simplifies the application development. The phone library supports a large variety of telephony interfaces. Multiple technology providers can be distinguished via their service name.
| Feature | Details |
|---|---|
| Telephony API | The Telephony classes provide a general purpose API which allows the integration of arbitrary telephony services. Currently the following telephony system integrations exist:
The call policy manager is responsible for the management of calls across multiple call types. |
| Telephony related user interface components | Due to a unified Telephony API the same user interface code can be used for the various Telephony services. This module includes the following UI elements:
|
| Modem Emulator | The Modem Emulator together with the ModemEmulator service enable third party devices such as Desktop PCs or other phones access to AT commands. This could be used to perform telephony operations on the external device's behalf. Such a feature is a requirement for some Bluetooth hands-free kits and any form of dial-up networking. The emulator even works on devices which only have VoIP telephony services. |
| Other features | The following minor features are included in this module:
|
The Telephony module includes the following software components:
The exact list of components included in this module can be found in $QPEDIR/src/module_telephony.pri.
