Hearing your own voice on telephone calls
The symptoms are that an incoming call is received and you hear your own voice delayed by a few seconds, which makes having a conversation difficult. You might or might not be able to hear the caller as well.
To hear your own voice, there has to be a loop somewhere on the network, thus sending your voice back to you. As there is a delay, we do not believe this to be a problem with your telephone system or telephone lines. The longer the delay, the further away from you the loop will be.
Even though we do not believe this to be a problem with your service, it is worth reporting this to your service provider so that the network provider becomes aware of it. If you are able to communicate with the person calling you, ask them to report the problem to their network provider as well.
