Thanks Mitelpassion. Yeah, he can do that. I think on mine though, it's broken. I'm not able to answer on my desktop phone at all. When i pick it up on the second ring, i get a busy signal, and then my cellphone rings. cellphone rings even when i hang up the handset.
I can only answer the desktop if i pick it up immediately after the first ring. Don't know why. seems to be working for everyone but me.
