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

VOIP - TargetsVOIP - 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
Slide 7Common SolutionsMay 14, 1999© 1999 Georgia Board of Regents
VOIP RequirementsVOIP Requirements
Bandwidth low, management highQoS, diffserv, MPLS, IPv6 w/RSVP
Need for “voice-grade” soundreliability Issues– hardened network– not at five nines level
Bandwidth throwing not the solution

IP Telephony MarketIP 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

VOIP - Side EffectVOIP - 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.
Slide 15Common SolutionsMay 14, 1999© 1999 Georgia Board of Regents
VOIPVOIP
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 TodayUSG 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
