No you need to purchase a device that operates on a different frequency-most hose phone do not change frequencies beside the Bluetooth ones, and it seems your is not. I suggest a 5.8ghz and a store that has a flexible return policy, RadioShack has a decent selection of phones around 50$ give of take, you could also go for a Bluetooth setup--Good Luck.

i have the same problem, looks like it is just a bad set up and taking it back. My guess is I had bluetooth setup at one point to sync my cell with the phone and the phone registered the mail queue of my cell phone and not the mail of the cordless phone unit, so despite clearing it from the cordless phone, it still thinks there is voicemail from when it last accessed my cell phone. Terrible...and I can't find a solution either and won't waste time doing so... returning it.
