Query: skype phone

this phone only works when you call out; sometimes when a person has had an old cordless phone calls, there is an annoying echo; and the phone only rings once. It is great to use after my computer is shut down; I can still use skype; it needs to have a better system for audio; the volume is not loud at all and if there is echoing, forget hearing anything; the worst is that I bought it and opened the package; the buyer would not take it back because I thought it was defective; I would have to send a brand new phone to the manufacturer instead of getting a refund for a not so good product. very disappointed in both product and the seller. Now I am stuck with an expensive phone that works some of the time.
