We have a Merlin Magic phone system. One person in the office has a phone with extension 123 and an outside line 123-4567. She's out of her office most of the time (she's a nurse) and would like to be able to receive and make calls on the outside line. We've been told that the price of a cordless phone for the system is too much. My question is this: Can I tap into the line before it becomes part of the Magic system and put a regular cordless phone on it? Will this interfere with the Merlin phone on her desk? Is this feasible? Thanks. -Joe
