Forwarding routes your incoming calls to one other device at a time. If your phone is set to forward calls, your desk phone will not ring. You may set and remove a forward manually at your will.
With Single Number Reach, your office line can ring on multiple devices at once, including your desk phone. No matter which device you use, you answer calls as though you are sitting in your office. Initial set-up must be requested through the ITS Help Desk. After set-up, you can manage your devices through Unified Communications Self-Service. Log in with your campus Net ID and password.
