Real-time Communications (RTC) Client API (Windows CE 5.0)

Send Feedback

Windows CE includes the Real-time Communications (RTC) Client API, which supports real-time communication between different parties using audio and text messaging.

The RTC Client API also provides presence functionality to locate available parties and communicate when you are available.

To provide its functionality, the RTC Client API uses industry standard protocols like:

  • Session Initiation Protocol (SIP)
  • Session Description Protocol (SDP)
  • Real-time Transport Protocol (RTP)
  • Public Switched Telephone Network/Internet Interworking (PINT)

The IP phone support in Windows CE is built using the RTC Client API. For more information about IP phone support, see Developing an IP Phone.
