Query: Drops calls

I purchased this adapter based the price and the reviews I read here.Pros:1. The convenience of using a cordless phone instead of being tied to the computer.2. The price.3. Sound quality is great.Cons:1. In the first day of use, the adapter dropped 4 out of 7 calls. The next time I tried using Skype from the computer, the adapter stole the call and dropped it (I could hear it click when it stole the call).2. You have to dial 00, the country code, the phone number, and * to make a call, and it sounds like your going to get the disconnected number recording (you know that sound that plays?) 3 times before it starts ringing.If it didn't drop calls, I'd give it 4 stars. But 4 out of 7 dropped is just unacceptable. Thanks to Amazon's great return policy, I am returning the adapter.
