I have been having an issue when answering incoming calls from different people, using both landlines and cell phones. We get a loud set of tones, making it impossible to hear the callers. Occasionally we do not have this issue, however, it appears to be occurring more often. Outbound calls do not seem to be affected by this issue. I have tried a complete reboot of the system, removing the battery and unplugging the unit. We have a wired phone and a wireless phone attached to the home phone hub and the issues has occurred on both phones. The home phone hub is getting good reception where it is located. Looking for any input to rectify this problematic issue.
