How to completely throw the university telephony guys:
"Hi, we're here because we're doing the phone updates..."
"Oh, yea, we got an email that everyone was going to voice over IP."
"Yea... but we're not sure if you're supposed to be updated?"
"I have no idea. I told my department head to take my phone, though."
*blink* *blink* *blink* *blink* "You...."
"Yea, we got an email a few weeks back about budget cuts and trying to find money in the budget, and one of the options was opting out of phone service. I told her to take my phone, I don't want it, I want my students to email me."
*blink* *blink* "Um, er, well... okay. Well, that explains why your line is dead, but I'm going to leave the set here until I get a disconnect notice, ok?"
