squeal on the line during any call

Post by fjgoslin » Fri Mar 16, 2012 6:01 am

I have had an OOMA Telo for almost 2 years now with out any problems. However, lately there has been a squealing noise on all calls in coming and out going. I have made no adjustments to the set up. We have 4 cordless phones and all have the same squeal...

Connect a hardwired phone directly to the Telo to verify that it is the Telo and not the cordless phone system causing the problem.

I had this exact same problem. I plugged a phone directly into the Telo and the squeal was not present. I then reset my doorbell that is plugged through the phone by unplugging it for 10 seconds. Once the doorbell was reset, the squeal went away. Problem solved!
