In a voice telephone call, an echo occurs when you hear your own voice repeated. Problems with echo are always originating on the far end of your call. This is due to the latency on your internet connection causing the delayed playback of your voice. This typically happens over traditional phone lines, but with minimal latency, the echo usually goes unnoticed.
There are two ways echo can occur:
Electrically through poor quality phone cables.
Acoustically (feedback) through sound waves between the phone's speaker and microphone.
We recommend asking the other party to lower the phone volume in order to reduce the feedback of your voice. If the problem is originating electrically, advise the other party that their telephone cables may need to be replaced.
As a last resort, try different telephone sets to reduce echo, as some telephones have special echo-cancellation technology. Quality of the telephone plays an important role. However, higher priced units do not always guarantee higher quality calls in terms of echo-cancellation. Echo- cancellation is dependent upon the internal technology of the telephone, and how the transmit and receive signals are exchanged. Some manufacturers (Panasonic among others) make phones with separate transmit and receive paths, which the companies claim, significantly reduce echo.
