Overall no major problems with the phone. Some difficulties with sound quality, but I don't know if it's phone vs. Cinguular.One major glitch is inability to switch into "hide number" in caller ID. When you do that, the phone stops dialing out after an hour or so. I thought it was a problem with a particular hand set, got a new one and same thing happens.Will have to exchange it, since I like to keep my number private
