My sister has a Panasonic KX-UT113 connected to a BT home hub 5.
She has two providers providing a line each. sipgate & localphone.
The problem is, the phone has been ringing all day and night with phantom calls from number 100.
I have a near identical set up, but i do not use the bt home hub 5.
Can anyone offer any advise on how to get the phantom calls to stop please.
