Making a Voice Call Using a Built-in Radio (Windows Embedded CE 6.0)
1/6/2010
OEMs can include a built-in GSM radio in a Windows Embedded CE powered device. You can program the application to use the radio to make a voice call.
To make a voice call, use Connection Manager and a voice application, such as Dialer or Contacts, to complete the following steps:
- The voice application calls tapiRequestMakeCall or ConnMgrProviderMessage with the TPC_REQ_DIAL_VOICE constant set.
- The voice Connection Service Provider (CSPVoice) module creates a connection request and passes it to Connection Manager.
- Connection Manager passes the connection request to Connection Planner.
- Because voice calls are higher priority, Connection Planner disconnects any active data calls.
- Connection Manager opens a voice connection.
