Seeing Windows Embedded CE IP Phones in Action (Windows Embedded CE 6.0)
In addition to understanding basic Voice over IP (VoIP) concepts, it is also very helpful to see the default Windows Embedded CE IP Phone design template implementation in operation.
The Windows Embedded CE VoIP phone application enables you to communicate with another phone without first configuring a full-featured VoIP network that includes elements like SIP servers. You can then add network elements as necessary to test additional functionality.
For example, you might not have a SIP server available on your network to handle call control tasks, or you might not be using Exchange for contact and schedule information. In the absence of a SIP server, two Windows Embedded CE-based VoIP phones can connect directly. This means you can connect two Emulator instances, two CEPCs, or a CEPC and an Emulator running on another development computer. Or you can connect an instance of Windows Messenger (which is a SIP client) with a CEPC or Emulator.
For specific steps you can follow to see how the default Windows Embedded CE-based IP Phone OS design solution operates, see:
