University of Minnesota local telephone service is changing configuration on Friday, April 11th, as OIT engineers move local calling traffic from third-party vendor SBC Communications to AT&T, due to the acquisition of SBC Communications by AT&T. The service change includes the porting of 40,000 local telephone numbers, as well as T1 moves. The transition begins at 6:00pm, and could take up to 24 hours to complete. Phone service should not be interrupted.
