CP930 Randomly mutes
We have a customer we just put in 1- CP960 and 4- CP930's connected to 3CX version 16. One of the 930's is randomly muting anywhere from 20-30 minutes into the call; all mute lights turn red. I verified it has the latest firmware and rebooted the phone. Has anybody else experienced this?

RE: CP930 Randomly mutes
Did not experience this issue myself however we have deployed couple 930W and customer has reported calls going silent after about 30 minutes. I wonder if that is related to the issue you have described. I will try to replicate this issue.

Do you have any issues with the latency on those 930's? I am testing with 3CX *777 echo test and i've got about 0.5 second voice delay comparing to 0.1 second delay on the normal handsets...

Any update on why this might be happening? I have the same issue with a newly installed device. The firmware is up to date.

Mark,

We have not been able to reliably replicate the issue. It has occurred randomly. Hoping to catch it next time I have wireshark running. I have a case open with tech support to address.

Thanks,
Scott

Hi,

Did you ever checked the power source?
If you use PoE, then replace it for a standalone power supply.

Hope this will help.

Kind regards,
Frank.

Thanks for the note - are you referring to the W60B base? To be clear, we should use a standalone power supply instead of PoE for the W60B base?

Hi,

Yes, I am referring to the W60B Base.
My experience is when there are randomly and intermittent issues, 9 of the 10 times the power supply causes this. That's why I suggested a standalone power supply... to test.

Kind regards,
Frank.
