Problem:

Why do calls fade/cut in and out when I’m using this phone?

Solution:

Tip 1 of 11

If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.

In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.

Please contact your service provider to obtain DSL filters and installation information.
