The University is moving from the current Bell Centrex system for telephones to a new VoIP (Voice over IP; essentially using computer networks to replace telephone networks) system. The change will provide enhanced communication features and significant cost savings.
The main University website for this changeover is VoIP at U of T.
Currently the Faculty of Arts and Science is in discussions about this changeover with the central people and the departments within the faculty.
More updates will be posted on this blog as the project progresses.
