Unified Communications (VoIP) FAQ

Services: 

Will I lose phone service during power and/or data network failures?

Unlike traditional phones, you may lose service in an event of power loss because the VoIP phones run over the data network. If the building network is on a generator and your phone is not plugged in to local AC power, your voice service will continue working. In an event of a building power loss, ensure that you have your cell phone accessible in case of an emergency.

We have built redundancy into our network architecture to increase reliability.

How can I access my voice mail?
