Does the noise occur intermittently or only when you contact a specific number? If this is the case then it is possible the issue is caused by a problem with the other person's service.

Please advise the person concerned that there may be noise occurring on their phone line.

If the noise is experienced on all your calls, move on to Step 3.

An isolation test can determine if the problem is caused by an external piece of equipment plugged into the phone line. Unplug / disconnect all phones and other equipment connected to your phone line. This includes any additional phones, modems, extension cords etc.

Once you’ve removed all extra equipment, plug in one telephone (preferably a corded phone) and make a test call. Continue reattaching equipment to the phone line and test the line each time.

If you experience noise on the line after connecting a specific piece of equipment you have identified where the issue lies.

If the noise continues, move on to Step 4.

Check for damage to the handset, buttons or cords. This may be causing noise on the line.

If the handset is damaged, Optus provides service assurance on Optus-supplied handsets for those customers either paying a monthly handset charge or who have purchased a device that’s still under warranty, (12 months from the original purchase date). For further assistance, contact Technical Support.

Optus does not provide service assurance for handsets supplied by a 3rd party.

If your equipment is free of damage, move on to Step 5.
