Northwestern Information Technology will be performing maintenance on the university voice system. We will be working with our local telephone service provider to migrate approximately 1450 of our Evanston telephone numbers to a new circuit. Once the moves are started, all numbers in the group will be unable to receive inbound off campus calls. Each number will return to service once it is migrated. On-campus calls as well as outbound calls will not be affected.
The work for this window will involve a small set of University critical numbers, some of which may be contained within the ranges below. The critical numbers will all be returned to service within 30 minutes; the rest of the numbers will all be returned to service within three hours.
If you have any questions about a specific telephone number, please contact the IT Service Desk at consultant@northwestern.edu or 847-491-HELP (4357).
