if you are using a DECT 6.0 phone made by Panasonic -- THAT may be the reason that you are having this problem. If you are using a DECT 6.0 phone move the base station to a different location and see if the problem goes away. You may need to try several locations.
This happened to me a couple of years ago ... and some very smart female tech got so fed up with my situation she called her supervisor and he asked her to ask me if I had a DECT 6.0 phone system in place
I replace all my DECT 6.0 PANASONIC phone with DECT 6.0 AT&T Phones ---- no problems. Apparently the Panasonic DECT 6.0 phones have some frequency issues with certain Cable TV channels.... and it varies which makes it very difficult to pin down which is why I switched brands.--
