Uncanceled Echo:

tbfnet — Mon, 10 Oct 2011 09:05:07 GMT

Hello all,

We have the bt business hub in our workplace and for the last two weeks I have seen this

Uncanceled Echo: 15.3 dB Suspicious - check phone filters and alarm

So I have changed the filter 4 times and still have the same problem.
We only have the ADSL on this line and the main phone.
I have tried the test socket and it's still the same, also when doing a line test it comes back clear.
Any ideas? as I'm pretty stumped.

Edit: Just noticed every time a call is made I can hear a noise on the line and the hub resets itself, also the max rate on the line is now at 3500k which I'm assuming is so the line can stabilize.

It is almost certainly a physical line fault ... (and I can guess which). Nothing you can do, it will require a technician to sort it out.

Call technical support and explain all of your findings to them ... If possible call from another landline if you can as they may ask you to try recreating the problem.

Today, bt sent a new hub, newer than the one i had and it shows no problems.
So i'm assuming whatever the problem was, it has been fixed.
