The Panasonic is really nice and good to use. I have to add my voice to previous speakers. The functions are almost all speaking. As the forwarding to another handset works, however, I have still not figured out is a bit annoying when people need to call always 2x. Unfortunately, it also solves my main problem is not that callers often have an echo and hear himself talk, especially when we receive a call from the mobile phone. Too Bad.
