Hi there I work in an office-where all 6 of us use this phone. However, we don't actually hold a copy of the instruction manual and between us, we can't figure out how to store numbers! Being a busy office, we are constantly on the phone and often ringing out to regular numbers, so it would be a great help to be able to store some of these numbers we use so often. I would appreciate it if you could therefore get back to me with some helpful guidance. Many thanks Aimee Williams
