VOIP - Hype
It’s about money, money and more
money - $1,000,000,000,000!
 Competition, marketing and market
share
 You too can use the noise in your
data circuits for fun and profit.

VOIP - Reality
“real savings are probably 3-4 yr.
out”, GartnerGroup, 3/99
 transition costs are high
 infrastructure not ready
 do we want to or can we become the
phone company?

– All cost of voice will be due to overhead

VOIP - Targets
WAN is where biggest impact will be
felt - look there first.
 LAN and intrabuilding are not
affected by voice
 convergence does not mean one
network
 but local service is a big ticket item


VOIP Requirements
Bandwidth low, management high
QoS, diffserv, MPLS, IPv6 w/RSVP
 Need for “voice-grade” sound
 reliability Issues

– hardened network
– not at five nines level

Bandwidth throwing not the solution

IP Telephony Market

From GartnerGroup 1999/01/01
– Although the Market for Internet-based
telephony should reach $3 billion by
2003, it will constitute just two tenths of
1 percent of the total network service
market of $1.4 trillion.
– IP Telephony is in “Slow Growth” stage
of technological maturity

Carriers Are Thinking about
VOIP
AT&T Global Clearinghouse for
billing, call admin., etc.; also testing
 ICG Netcon On-Line testing now at
5.9 ¢/min in 166 cities
 Qwest testing now at 7.5 ¢/min in 125
metropolitan service areas
 Sprint testing now at 7.5 ¢/min

VOIP - Savings?

voice/min. price drop
– CCLs demise (from 2.7¢ to 0 ¢ by ‘01)
– DWDM improving efficiencies

expected 3 to 5 cents/min. for LD

IP Telephony Opportunities?
Bypass long distance
 Reduce # of access lines
 Cost savings, maybe
 Convergence of technologies
 Focus on IP network, not multiple
nets
 Integration with video
 Integrated messaging


VOIP - Why Bother?

Opportunities
– take advantage of higher education’s
unique environments
• educational intranets w/ end-to-end
possibilities
local - state - regional - national - global

VOIP - Side Effect
Communications envelope approach
(comprehensive infrastructure)
 Socialize “zero sum savings”

– communications costs should remain
constant or increase with demand. The
decreasing unit costs for voice should
be redirected to cover data.

VOIP

Scenario
– best solution maybe to encourage someone
else do voice/IP at savings approaching what
we can obtain and with redirection of savings
inside a communications envelope to cover
data.

USG LD Costs Today

Total LD ~ $6,000,000 annually
– Within Georgia ~ 10 ¢ per minute
– Outside Georgia ~ 14 ¢ per minute
– Credit Card ~ 15 ¢ per minute
– Intra 40%, Inter 55%, Credit 5%
– 63 million call minutes
If we could save 1/2 of it somehow …
 $6M x 40% x 1/2 is $1.2M

Trial LD Solution
Use existing telephones & PBXs
 Use standard interior phone lines
 Keep familiar dialing plan
 Requires staged dial tone
 Dial into Atlanta only; not symmetric
 Limited accounting
 Avoid becoming common carrier

Trial Questions
Quality
 Compatibility (with existing telco)
 Ease of use
 Costs projected for more sites
 Interoperability (with other VOIP)
 Maximize throughput & minimize
latency, independent of traffic
patterns
