Just had Fibre 150 installed, and kept land line number, connected by digital voice adaptor. But we are having trouble. We can receive calls no problem,during initial caller discussion we have trouble when someone else rings our landline number during the initial call. The connection produces 2 bleep sounds, the initial caller goes mute, and the initial caller then gets cut off, with the second caller then connected. All this takes just seconds to lose one call and connect second caller.This is getting very frustrating, and needs sorting
