Hello,
I'm trying to generate a ringback tone for a call (the user that made the call should hear this ringing). So when the call receives the Ringback status, I'm calling
lineGenerateTone(hCall, LINETONEMODE_RINGBSCK, 0, 0, NULL)
The problem is that I keep receiving Invalid Tone exception. Should I do something differently, or this is something that needs to be set on the server?
Thanks,
Istvan
