I don't know of any provider here, although Magnet Entertainment provide a TV, landline and broadband package (I have no affiliation with Magnet). I am surprised that no company has started such a service here - in France it is very common, and when people are in their house (apparently where people use their mobiles most), the calls are routed on VoIP.
The reason for having all services from one provider is that it will work out cheaper.
