Help! I had to make an emergency trip back east this week and my mom wants me to fix her telephone while I'm home. In her kitchen she has a 25 year old telephone mounted on her wall. She wants it replaced with a cordless phone. The problem is I have to figure how to get it off the wall (the way it's mounted, I can't see anyting to release), and then there's the problem of no jack there. The phone is wired right into the wall. I'm handy with computers and audio/video. Telephones just aren't my forte. Any suggestions? Thanks!
