All four ports on the HT814 are in use and registered.
The system is not yet operational because the extensions are waiting for final number porting.
Every few minutes or so one or two ports are in Ringing status, sometimes simultaneous.
A CLID is not displayed and when the phone is picked up it is quiet.
This looks like “ghost calls”. Being generated by the ATA itself.
Could this mean a hardware of firmware problem with the HT814?
