Communications: Telephony
Functional Description

Qtopia provides versatile functionality for traditional GSM telephony together with GPRS and Voice Over Internet Protocol (VoIP). Qtopia telephony is integrated intuitively with the user-interface and provides the ability to choose between either GSM or VoIP when making calls to a contact with both a phone number and VoIP identifier. An enhanced telephony integration mechanism based on the VoIP integration model allows different modems and different phone-like transports , for example, SIP, to be more easily integrated. Features include: split serial port, AT chat handling and multiplexing. An improved vendor plug-in mechanism allows vendors to directly inherit AT handlers and override individual functions.

Qtopia also provides an Over-The-Air (OTA) facility that allows the network provider to send a set of network configurations to a mobile device with no user interaction required to create a working connection. A SIM Toolkit provides a user-interface to allow service providers to develop phone applications without modifying or installing software on the phone.
