I'm asking this for a friend who has works at an elderly care facility. He's wondering how much a he might expect to pay for a 24 channel MDU Bulk Rack System and Installation (that's the term he gave me). He's also wondering how much it might cost to add an in-house channel. Don't ask me alot of follow up questions, because I'm not really in the know. I think he's just looking for ballpark figures. Thanks!
