What is VoIP?
• Voice over Internet Protocol (VoIP):
carry voice calls over an IP network
• the digitization and “packetization” of the
voice streams

Why VoIP Services?
• Obtain the Benefits of Convergence
• Maximize UF’s Network Investment
• Take Advantage of Emerging Services
• Video Telephony
• Enhanced Conferencing
• Unified Messaging
• $avings, $avings, $avings:
• Lower operating costs
• Lower rates to departments
Benefits of Convergence
With convergence you maximize the
network investment:
• Fully leverage existing network infrastructure
– Eliminate separate networks for voice and data
– One “line” to the desktop
• Simplify and reduce costs of ongoing network
administration
– Improve staff efficiency (More with same or less)
– More services on same network
Benefits of Convergence
With convergence you reduce the total cost of
network ownership:
• Simplify and reduce application integration costs

computers with the
functionality of IP Phones,
providing high-quality voice
calls on the road, in the office,
or from wherever users may
have access to the network
– UF currently testing
VoIP Savings:
• Lower Operating
Costs:
• Reduce UF’s BellSouth
Line Costs
• Moves, Adds &
Changes:
• Faster response
• No BellSouth Charges
• Departments can make
changes on their own

costs due to one
campus system to
support vs. the +5 types
of current systems
• Lower inventory costs
• Training costs will be
lower
• Lower rates to Campus
Departments
Summary
• Convergence
– Maximizes UF investment in network
• Cost Savings
– Lower operating costs
• New Services
– Positions UF to take advantage of new
applications on an enterprise wide basis
