The functional program of the calling phone can only be provided by the service provider, and the Web you want to do is to call the COM component, huh, huh, you will see the interface provided by this component.
-------------------------------------------------- -------------
-------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------------------
This page allows the user to call the specified address and accept the call.
Phone operations are: creation, connection, answering, hang up
When you receive the phone ringing, you can set the priority of the phone.
QoS guarantee (QoS generally evaluate from the call setup time, packet loss rate, jitter (delay), MOS value, and end-to-end time to extends several aspects.)
Managing videos need to use the iVideoWindow property of the TAPI control, and the Handle does not get the Window in VBScript, so the video is not called.
Note: Call the iVideoWindow property can only occur when "stream Active" event occurs.
