One way audio issue

Hi Everybody,

I have a new issue with the UC320 W of one of my clients. After resolving with your support a problem with the disconnection tone, now I have a new issue. The problem of this new issue is that it doesn't happen at every call, but just sometimes, and I cannot understand if randomly or with some logic. When somebody calls one of the 3 lines connected to the FXOs, sometimes the caller doesnt' hear anything, while we hear him, and this happens also when the Voice Mail or the Auto respondant answers. As I said before, it doesn't happen at every call: in fact, if the caller hangs up and calls again, everything works fine. I have the last firmware updated as well as the last region pack (Italy_x3_v1). Also installed a PMF sent to me by Cisco (

Manual Entry Disconnect Tone.pmf) that allowed me to manually entry the disconnect tone. I wish somebody could help me quickly, because the client started to be tired of having always some issue...

Hi Stefano,

How long is the system up time? You can find out from Status-> Devices. What is the firmware release? If it's the latest firmware 2.3.2(6), could you please perform fxo/fxo loopback testing and fxo/fxs loopback testing at Status-> Support Tools.

Best regards,

Wendy
