There has been a problem the last week or so when I get home and talk on the centro or dlx I have problems with the phones echoing. I have tried to call about 2 other service providers and I land line and I am having this same problem. This has only happened when I am home and the coverage here is not bad. I did try to go outside and same thing. I also wanted to add that as crazy as this might sound I went right under the sprint tower and a block away where the panels are pointing and nothing. So does anyone here have any ideas what might be going on similar problems you might have? The problem seems to affect the other person as well when they talk to me. I know this is a not my hardware since this only happens in a single area??
