I've been getting calls fwd from the office I tech support the last few days. Checking the 5 phone voip system yesterday pm I find big oops. All flashing setup issues. Can call out, but incoming come to me. I check CenturyLink and find all our phones now unsupported/deprecated as of September 30. No notification emails over the last year. Must find 5 new Cisco phones ASAP. Found 1 last night. Need a support call this am to activate it. 1 cuppa #coffee and I'm out the door. Wish me luck.

Had to get a different phone, but it works.
5 new open box on order from eBay arriving early next week. Problem mostly solved.
