UC320W-FXO-K9 voicemail disconnect issue

[tomalbertson]

Hi,

We recently installed the UC320-W-FXO-K9 and noticed that if a caller hangs up during our recorded voicemail message (so after the ringing is completed and the voicemail app has started, but before the user is prompted to leave a message) then the system records a blank voicemail that is about 18 to 25 seconds in length and obviously completely blank since the user already disconnected.   So it seems that the system eventually recogonizes the disconnect has occurred (though it doesn't go the full 10 minutes like other issues I found on this community), but not before it does the 18 to 25 seconds of blank recording.

Note:  We did run the impedance tool during set-up.

Any suggestions?

Thanks in advance,

Tom

Hi Tom,

We need to do FXO audio capture to see the CPC disconnect tone, then we may need to build a special PMF for that tone.

Please contact the Small Business Support Center at the phone number listed (Please pick the appropriate phone number in your region) in the link attached. One of our Engineers should be able to help you with it.
