This function puts the active call on hold.

DWORD NetworkHoldCall(void);

Parameters
none

Return values
Zero indicates success. A negative error number indicates that an error occurred. For additional error information, enable the library debug mode.

Remarks
The call on hold is temporarily disconnected allowing the application to use the line device for making or answering other calls. The NetworkHoldCall function performs a so-called "hard hold" of the specified call (as opposed to a "consultation call"). A call on hard hold typically cannot be transferred or included in a conference call.

Requirements
OS Versions: Windows CE 1.0 and later.
Header: dyntapi.h.
Dll Library: dyntapidll.dll.
