If a whisper is heard from an VDN, the whisper must be playing from an announcement board in your system. If you have a VAL board (TN2501AP), you can use VAL manager or you can FTP the wave file directly to the VAL announcement board.
Taken from VAL Manager help notes:
VAL Audio File Format Requirements
In order to be compatible with the TN2501AP circuit pack and the voice system, announcement recordings must have the following parameters:
· CCITT A-Law or CCITT Mu-Law companding format (do not use PCM)
· 8KHz sample rate
· 8-bit resolution (bits per sample)
· Mono (channels = 1)
If you are hearing another whisper, I bet the call is routed through another VDN that does not have VDN override set to Y.
Thanks,
