Frequently Asked Questions

I can hear noise or an echo on my telephone line.

This can happen due to a number of wiring issues.

Step 1: Disconnect your ADSL device and microfilters. Connect all telephones directly into their sockets. Turn off your ADSL device and remove the micro-filter from the wall socket. If you are using a telephone device on that wall socket, plug the telephone device connection directly into the wall socket. Remove all other micro-filters from their sockets and place each telephone connection directly into the wall socket.

Step 2: Check your telephones for noise or echo.

a. Go to the telephone where you noticed the problem.
b. Check to see if the noise/echo you heard is still there. If there is no problem, GO TO STEP 3.
c. If you still hear noise/echo, replace the telephone set with a different telephone that is trouble-free. Check for noise/echo. If there is no noise or echo, permanently replace the faulty telephone set and its connections.GO TO STEP 4.
d. If you still notice noise or echo, check all other telephone sockets,one at a time using a good telephone. Replace any fax machine with a good telephone set. If all other telephones have noise or echo, there may be a problem with your telephony service. CONTACT BT'S FAULT SERVICE by dialling 151.
e. If there is noise or echo on only one telephone socket, there may be a problem with your telephone socket GO TO STEP 4.

c. Check for noise/echo again. If you notice noise or echo, there may be a problem with the micro-filter. Replace the filter with another and check for noise or echo again. If now there is no noise or echo, the original filter on that socket should not be used.
