Agree with poweroffuet, to try to convert to VoIP. I was lucky on one house move, where my personal office phone number was not acceptable to new area, but I was able to transfer to a VoIP account. At the time internet was slow so after awhile, I quit using the Ethernet phone adapter, and just used that number for receiving calls. Voice and fax calls are all sent to me by emails. It's been over 20 years now. Works great. (Since I don't have a device to connect, my yearly fee is fairly low.) I assume that at some point I could always hook up telephone, and take advantage of the modern internet. Although, I really like this system, and it isn't connected to any particular location.
