I have joined this thread with a somewhat different kind of fault.
Have had difficulties registering the phone to the base and sometimes given up and just left phone in cradle aparently unregistered.Then go to it later and find it is working perfectly,displaying Phone 1, and antenna symbol is steady! However after some indeterminate period of time it is no longer working.displaying Base 1 and and antenna symbol is flashing.
I have been round most of the buoys.Checked and replaced batteries:run rescue from the Hub Manager etc.
Should I give up,(I can get broadband telephone service from phone in hub phone socket) and throw it in the dustbin or has somebody a solution?,
