How to call in a powercut?
Currently home phones lines provide "power" and will (or should) work in a power cut. So calling emergency services (or even the power company) in a powercut is still possible.
Now with switching to VOIP we are told to call using mobile phones in powercuts. We too live with poor mobile signal indoors, my company even provided a femtocell to route calls over the BB but in a power cut...?
