Voice over Internet protocol, or VoIP, allows users to make and receive calls using the internet. Instead of transmitting a call from a hardwired desk phone through a network of switches and wires, VoIP converts voice communications into digital data that travels over an internet connection to its destination. 

UCSB will utilize Zoom Phone for our voice over Internet service. With a single platform utilized for voice, chat, and video, users will make phone calls with the same ease and familiarity as Zoom video meetings. Visit our Zoom Phone training page for helpful videos and reference guides.

Over the past several years, organizations of all sizes have turned to VoIP to replace their legacy phone system and give their employees the tools they need to communicate in an increasingly mobile world. Extensive business features give users incredible flexibility to make and receive calls from anywhere without being dependent on a physical location like an office desk phone. VoIP calls can be made with any device that has a reliable internet connection, including a desktop, laptop, smartphone, or tablet.
