A few weeks ago I started to have occasional interference on my landline but only on outgoing calls - all incoming calls are clear. The interference can also be heard by the other person. Since then it has increased and reached the stage where making calls is a waste of time as it is next to impossible to have a conversation. I have carried out the steps in the guidance info including replacing the micro filter with a new one yet nothing had improved. Advice please.
Just one last thing to try before calling Now. Try in the test socket (if you have one) with 2 different hand sets. If they both have the same problem in the test socket it must be a fault on the line (but a very odd one) and Now will need to call out Openreach.
To call Now use the number in this link: How to make a complaint (nowtv.com)
