Economics of Internet Telephony
George Vinall

Discussion Topics
  • Diagrams of IT services
  • Cost vs. Circuit Switching
  • State of the Economics
  • International Settlements
  • Domestic Access Charges
  • Regulation Public Policy
  • Logical Conclusions

The Question Is Internet Telephony a legitimate
new industry or a just a passing arbitrage
opportunity built on the avoidance of
international settlement payments and US access
costs?

Arbitrage
  • Avoidance of ITU/FCC international settlement
    payments to foreign carriers
  • Avoidance of certain domestic access charges
  • Use of public Internet backbones for traffic

Clever Pricing Formats
  • Good News
  • Real rates are mixed, some higher than IDDD
  • IT from US Gateways just resold IDDD bought at
    carrier rates
  • Hybrid IT, resale per route
  • Postalized international pricing (with sever
    restrictions)
  • Bad News
  • Change customer behavior
  • PC - to - PC captures low-end
  • Phone-to-Phone facilities costs are higher
  • Phone-to-Phone pricing requires scale,
    terminating facilities

22
State of the Regulations
  • History of Computer III
  • Is Phone-to-Phone exempt?
  • IVANs
  • General US policy
  • FCC, White House, Congress
  • General International policy
  • ITU, WTO Accord
  • Reciprocal Compensation for CLECs

23
Logical Conclusions
  • Internet technology is a not an immediate treat
    to carrier grade service
  • Cost savings is solely based on avoidance of US
    domestic access fees and international settlement
    payments
  • PC-to-PC best cost service, but relies on spotty
    quality of the public Internet
  • Inherent efficiencies require scale,
    technological development, bandwidth management
    tools
  • If traffic grows, regulators will start changing
    rules, charging IT carriers

The Bottom Line Internet Telephone both benefits
from and suffers from a similar cost/service
structure as line-side dialing (Feature Group
A) telephone service did between 1980-1984
