IP Phone Suite OS Design Development (Windows Embedded CE 6.0)

1/6/2010

The IP Phone Suite is a fully functional and customizable suite of applications that, together, offer standard and advanced IP phone functionality. The IP Phone Suite uses the PhCommon dynamic link library, the VAIL Database Store, Real-time Communications (RTC) Client API, Exchange Client, the State and Notifications Broker API (SNAPI) and the Pocket Outlook Object Model (POOM), among others.

For more information about building an IP phone using Windows Embedded CE, including links to other VoIP-related catalog items, see Developing a VoIP Phone.

OS Design Information

The following table shows operating system design information for the IP Phone Suite. It does not show all the dependencies, just the core dependencies. For a complete dependency list, please see the IP Phone Advanced Design Template and look at the advanced phone case.

Concept	Description
Dependencies	COM RTC Client API Exchange Integration (used if available, but not required) Pocket Outlook Object Model (POOM) (used if available, but not required) VAIL Database Store PhCommon State and Notifications Broker (SNAPI) Phone IME TCP/IP XML
Hardware considerations	Audio hardware appropriate for your use cases Network connection In addition, the capture device and driver used by the VoIP device should be able to handle wave-in capture buffers as small as 10 milliseconds and return them to an application when they are filled with data. Ideally, peripheral hardware like the microphone and earpiece should have automatic gain control and built-in echo cancellation.

Modules and Components

The following components and modules implement the IP Phone Suite. This list does not include non-catalog but related items, such as Phcommon.dll and the IP Dialer core library, phonecore.dll. Note: All modules are executables, with the exception of the VAIL Database Store, which is a dynamic link library.

Item	Module	Component
IP Dialer	phoneapp	None
IP Home Screen	homescreen	None
IP Settings	phsettings	None
IP Contacts	phinfo	None
VAIL Database Store	voipstore	None

Implementation Considerations

The following table shows the core Sysgen variables for the IP Phone Suite, but also includes the VAIL Database Store as well. It does not show the other core component dependencies that have catalog items, like the RTC Client or Exchange. For a complete dependency list, showing all the Sysgens, please see the IP Phone Advanced Design Template and look at the advanced phone case.

PhCommon does not have a catalog item. It is included during the build process.

Sysgen variable	Description
SYSGEN_VOIPPHONE_PHONEAPP	IP Dialer Application
SYSGEN_VOIPPHONE_HOMESCREEN	IP Home Screen Application
SYSGEN_VOIPPHONE_SETTINGS	IP Settings Application
SYSGEN_VOIPPHONE_INFOAPP	IP Contacts application.
SYSGEN_VOIPPHONE_DBSTORE	Adds the VAIL Database Store for caller information and call logs database implementation.
