Using ITAPI3 on telephony card with TAPI2.0 driver

Jul 5, 2013 at 8:58 AM
Hi, Can this ITAPI3 be used to develop application for a telephony card which has only tapi 2.0 campatability and the corresponding wave form audio?

When we tried the ITAPI3 sample "ConversationRecording ", it can open the TAPI lines of the card; But when we try to playback the wavefile "Welcome.wav", the PlaybackTerminal is null;

Thanks in advance

TAPI 3.0 is the minimum requirement for media - thats where those APIs (COM based) were added. The TSP must include a Media Service Provider (MSP) as part of it's logic to support that. So you can do call control with ITAPI3, but not media control.
