We have our Phone Power VOIP "home" phone service forwarded to one of our cell phones so we don't need to lug anything else along with us. The forwarding is set so if the first phone doesn't answer after several rings, the second cell phone rings. A no answer there goes to voicemail. Both cell phones have an app for the VOIP service installed that lets us make calls using the VOIP service. I don't know if the Verizon Home Phone cell service supports any of that, although I'm sure it supports basic forwarding at least. At $35/year using an ObiHai phone adapter, our Phone Power service is a lot cheaper though.
