This means I can finally bite the bullet and make the switch from landline to cell phone and not have to worry about missing an important business call just because I'm not on the same floor in my home as the cell phone. And I won't have to pay $30 a month for landline service to do it. Here is a video explaining how it works:
The only part I can't figure out is if it can make it ring to multiple phones if the multiple phones are not hooked up to the device. Does the Gigaset send a signal to every phone in the house? The video is not clear about whether or not I need a special expensive phone or phones to do that. And reviews say the company provides no customer service so I won't be able to call them and find out.
