Voice over IP
Spring LNA Meeting
April 1, 2002
What is Voice over IP?

A technology for transporting integrated
digital voice, video and data over IP
networks.

VoIP is considered by some as the next
evolutionary step in the digital transmission
of data

The technology that turns voice
conversations into data packets and sends
them out over a packet switched IP network.
VoIP Charter

To determine the feasibility and validate the
business benefits to Stanford of implementing
VoIP.

Evaluate features and benefits of IP
telephony while exposing the potential risks.

Assess potential operational savings from a
converged voice and data network.

Answer the question; “Can IP Telephony be
the primary telecommunications solution for
Stanford University?”
VoIP Objectives




Establish a hardened end to end network
utility
Provide a converged voice and data network
Move communication and network
equipment out of Forsythe
Increase network functionality and mean
time to deploy services
Simplify network in closets and office with the
shared use of the data network
 Immediate activation when moving a phone
 Desktop enhancements and mobility

VoIP Objectives

Ensure redundancy across the University
with no single point of failure

Retire the current voice switch

Position Stanford at the forefront of
integrated voice, video and data that could
enhance our partnerships and corporate
relationships

A major advantage of VoIP and internet
telephony is that it avoids the tolls charged by
ordinary telephone service.
VoIP Pilot Scope





Evaluate vendor’s proposals and decide
technology for pilots
Pilot sites will be Gates/Computer Science
and five sites within ITSS
Perform a physical inventory of the closets
for each pilot site
Evaluate and upgrade the network backbone
and core infrastructure
Provide tools and training for voice and data
engineers
VoIP Pilot Scope






Evaluate, design and test voice features and
functions based on voice requirements and
regulations
Resolve the policy and technical issues that
will impact the expansion across campus
Create end-user documentation and training
Implement approximately 650 IP phones
Define the ROI
Evaluate cost model options
VoIP Pilot Scope





Partner with Campus IT Directors
Survey the client community
Make go/no go decision
Decide on vendor
Define future deliverables in a phased
approach
VoIP Constraints and Risks




Consider the current University budget
constraints when considering a project of this
magnitude
Campus acceptance of the utility model for a
converged voice and data network
Removal of the voice switch will be based on
resolution of all the technology challenges
associated with the voice features
There is no like environment that has
implemented VoIP, so there are no best
practices
VoIP Considerations and Assumptions




The project team will be managed by ITSS
with active participation from campus IT
units
The focus and direction will be closely
aligned with the TMIS project
The project funding will be identified and
approved
The project will be implemented based on a
phased approach
VoIP Considerations and Assumptions



ITSS will merge the current expertise to
support a converged network
The network must provide the same
reliability as the traditional PBX
For the implementation outside contractor
resources will be required
Suggestions??

How would you like to be kept in the loop?

What else can I provide about this project
that would be helpful?
