Adding Push-to-talk Support (Windows Embedded CE 6.0)
1/6/2010
Push-to-talk (PTT) is a half-duplex communication method. The user experience is similar to the experience of using a "walkie-talkie". When in a PTT call, a call participant pushes a button when speaking, and releases the button when listening.
Generally, to add PTT support to a device, an OEM must do the following:
- Implement the RILCALLTYPECALLBACK function, which identifies PTT calls.
- Set the PTT registry settings appropriately. See RIL Registry Settings.
The PTTExample.exe application is a test application that illustrates PTT call handling. Source code is available for this application*.*
