I have spent a long time with a previous helper and paid for the assistance but the problem is still not fixed: I can make outgoing calls but not receive incoming calls - a message comes up saying the number is 'unavailable' - not sure if that means the number of the caller or my number. I have checked the privacy settings but there does not appear to be a lock symbol which the manual says would be there if these settings were on. I have a Uniden XDECT 8355 Series with 3 handsets.
