Enhancing Campus Communication: Upcoming Phone System Change

We are making a significant upgrade to our campus calling system, aimed at enhancing the quality and reliability of our communication services. In 2025, the university will be transitioning to Microsoft Teams Voice. MS Teams Voice is a cloud-based phone system that integrates with Microsoft Teams, allowing you to make and receive calls directly within the Teams app, enhancing communication and collaboration. This upgrade is crucial to better support the needs of our university in a post-pandemic enterprise.

Migration from Cisco Phone System to Microsoft Teams Calling

We are excited to announce the transition from Cisco telephony to Microsoft Teams Calling. This campuswide initiative connects the university with the latest telephony technology. This change aims to streamline our communication systems and remove the reliance on physical hardware for the delivery of telephone service, all while making it easier to connect not only across the campus, but also with remote and hybrid faculty and staff.

We will provide further updates and detailed instructions as we approach the transition dates. If you have any questions, please reach out to the Service Desk.

Service Improvement

We have received your feedback and, after extensive data collection, it was determined that the current system was no longer the ideal provider to meet the evolving needs of the university. As working conditions have advanced to include more remote and hybrid team members, we need an enterprise solution that will better serve the campus both in accessibility and quality of service.

What is changing for users

The biggest changes that users will see are an improvement to service quality and physical equipment. All physical desk phones will be removed as they are only functional with Cisco. Only those departments, units or individuals with a demonstrated business need (such as reception desks, lobby phones and labs) will receive a new physical desk phone. The department or individual will need to make a request and we will work with you to find the best solution that will meet your needs.

Headsets will be used instead of physical phones for all other users. If a department, unit or individual needs a headset and does not already have one, we will work with you to ensure your needs are met.

What is not changing for users

While the provider and equipment will be changing with this migration, there are key services that will not be changing for users.

Current billing and existing phone numbers will not be changing with this migration. Your department will be billed the same amount as it was with Cisco and you will continue to be assigned the same phone number.

Frequently Asked Questions

Currently stored voicemail messages will not be carried over from Cisco. Microsoft Teams has its own voicemail system that transcribes messages and sends them to your email. In addition to the email, users can access their voicemail directly through the Teams Application.

If there are any current voicemails on the Cisco system you need to save, please download them to a university approved storage system such as OneDrive.
