Introduction To VoIP

Voice over IP (Voice over Internet Protocol or "VoIP") technology converts voice calls from analog to digital to be sent over digital data networks. This allows the university to use its existing data network (which includes fiber and copper wiring between and within buildings, and Cisco routers and switches) to also transport telephone service throughout the campus. By offering Voice over IP (or VoIP), UofL is moving toward a "converged" network, where voice, data, and video all travel along the UofL gigabit network.

VoIP compared with Centrex phones

What's the same?

  • Telephone number
  • Same dialing pattern for local and long distance calls

What's different?

  • Seven digit dialing for all campus calls
  • All telephone features will be included for free:
  • Caller ID with Name
  • Call Waiting, Call Forwarding, Conference, Transfer
  • Message Logs (missed calls, received calls, placed calls)

Benefits of VoIP

  • The VoIP system offers UofL many benefits as a replacement for its current telephone technology: VoIP uses a single communications network for both telephones and computers instead of the separate phone and computer networks that are prevalent today
  • VoIP uses programmable sets that provide new features, applications and capabilities such as allowing the university to quickly relay alerts or messages to all locations.
  • VoIP makes it easy to administer the system and individual features can be configured through a simple web interface.
  • The IP phones can access the university phone directory, allowing users to find the most up-to-date telephone numbers right on their phones.
  • Using VoIP positions the university for future technologies and future needs of students, faculty, and staff.

Users will be able to store a Personal Address Book and Fast Dial list, either using a Web interface or through manually entering information on the IP phone set. The speakerphones can be used in emergencies as a Public Address system.
