It is possible that the ADSL filter you’re using could be faulty or that there is an unfiltered device on your line. It would be a good idea to isolate the ADSL service i.e. disconnecting all other telephony devices and then try calling your phone number. You should notice that the service doesn’t drop out. If not, you could try another filter.
This could also be due to incorrect filtering. Please check our filtering guide in the General guides section to ensure that you have connected everything properly
