That sounds like a recording of calls I've logged with Cisco TAC ! I especially liked the one many years ago where the engineer insisted that there was no problem as he had thoroughly tested the ios in the Cisco lab. When asked if they had an Exchange with e1 ports to simulate incoming calls to the as5300 he replied, "E1 ? we don't use E1's in the states buddy"
Mmmm, TAC calls! My favourite!
"Our GSR is faulty!" "Nahhh .. not likely. That's crazy talk!" "No, really! There's a CEF problem we think.." "Turn CEF off." "It already IS off." "Oh .. then turn it on." "We _tried_ that. It made it worse." "Oh .. then upgrade IOS." "It's the latest stable version with the featureset we need!" "Oh .. then downgrade IOS. Can I close this ticket now?"
