I am sure they will handle trouble calls the same way it has always been handled during a strike before. There will be people to answer your call in Denver. They will, however, be managers. Lucent/Avaya has generally staffed Denver with more knowledgeable managers during a strike, but they are managers and have been away from the day-to-day customer support. Especially on the new products. Tier 3 and tier 4 are managers but they are going to be very busy helping all the new "technicians". You will get an answer, but it could take a while, be patient. You will
NOT be told to go away until the strike is over, once your call is answered you will get help. If you call to find out how to program a Call Pickup Group, your call may be short.

But if you call because the switch crashed, you will get help.
If, on the other hand, you were going to start an upgrade or install, those will usually be put on hold so existing customers can be supported.
