I was planning a simple project that turns on these vintage lights and rings a bell when you press a button - the lights and bells have sentimental value to many folks in my company - it was just going to be a stand alone little deal. Then someone suggested I make the lights and bell go off when some one calls the office phone. I think this is a great idea...but, I am not sure how to implement it - if fact I have no idea where to start. The phones we have are VOIP, connected via CAT5 cables... I would prefer not to have to hack the phone - as they are CISCO and I may or may not reap the consequences for breaking one if I don't get it right the first time...but I would still consider this option. Any thought on how I might pull this off?
