Query: Poor Sound

This phone with answering system was very easy to use, but the poor quality of voice sound made it fail the most basic test. I typically love talking to friends and family on the phone, but during the few days I used this phone the voice sounds were so annoying I couldn't wait to hang up.An additional missing feature is what I now know is called "chain dialing." This feature allows you to use several memories in sequence. My older AT&T; phone allowed this without any special feature beyond having several memory locations. Without this capacity, using a long-distance phone card that requires an access number plus a PIN number prior to dialing the number of the person you're calling becomes arduous.
