Possible to cause a station to auto-dial?

here’s my situation… My wife’s younger brother’s going to be staying at our house next weekend. He’s going to be alone in the house for one of the evenings, making sure our sleeping son doesn’t wake up. We’d rather not have a 17 year old here with unfettered access to our phones.

So, I’d like to give him a cordless phone that’s an extension on the system, and when he takes the phone off-hook, it automatically dials an IVR menu that gives him the options to dial my phone (1), my wife’s phone (2), or 911 (say 9).

Any thoughts?
