I have a BT7660 with 4 handsets. This system has been working well for months.
Suddenly none of the handsets will ring if a call is incoming unless they are in their cradles.
Can anyone help, please ?
Welcome back to this user forum for BT Residential phone and broadband customers.
Have you tried replacing the re-chargeable batteries?
You can prove this by temporarily swapping the batteries to ordinary alkaline ones, but do not put it on the charger base.
If the phone works with alkaline batteries, then it proves the rechargeable ones are no good, and need replacing.
Have you tried turning off the power to the base unit for about a minute, just in case the DECT communications are locked up? That would be the first thing to try.
