Yeah Dave- I have been having trouble here and there with mine. I loose mine altogether, when I try to call I get a message saying “this line can not connect to the Vonage network”. I can use the phone, next time there is nothing, then as soon as I try to call them, it comes back on. I have tried rebooting my phone adapter and cable modem, but doesn’t seem to help. It’s a PITA, but I use my cell more than my home phone anyways.
