While my PC showed the date as Friday February 29, 2008 my Nortel 1140E phone showed the date as March 1, 2008 (actual display reads “CS1000 03/01 8:14AM”).
The time/date on the Nortel Call Server was correct along with the time/date on the Nortel Signaling Servers. This was one of the weirdest issues I had ever seen. We opened a ticket with our voice reseller and waited for a response. It wasn’t too long before we recieved a reponse from the reseller along with an PDF document from Nortel.
It seems Nortel has released a bulletin describing a problem with Leap year that affects all Nortel IP Phase 2 phones. Unfortunately there’s no solution other than waiting for March 1, 2008 to actually come around (tomorrow).
