Steps to Make Long Distance Call 1. Subscriber dials local phone number of Service Provider (call leg A) 2. Subscriber gets second dial tone and is prompted to enter
Experience Similar to Using a Calling Card
Destination phone number Account number and password if calling away from home
3. Call is completed to the destination phone (call legs B and C) 1203 0993_05F9_c3

© 1999, Cisco Systems, Inc.
35
What Are Wholesale IP Minutes • Service Provider resells international minutes to other carriers as a carriers’ carrier • On a call-by-call basis, Service Provider selects the Internet, their “private” Internet or other wholesaler • Selection based on voice quality available at the time of call setup 1203 0993_05F9_c3

Why the Interest? • 94.1 billion international voice minutes in 1998 • International voice tariff umbrella remains high and relatively noneconomic-based • Technology now enables it • COGS of each Internet-based minute is extremely low 1203 0993_05F9_c3
37

What Is Internet Call Waiting? • Alternative to a second line for ISP subscribers • On busy-call-forward, the application suspends the call and presents the subscriber with alternatives Ignore the call Redirect the call to vmail Terminate ISP connection and take the call Take the call over the Internet 1203 0993_05F9_c3

Why the Interest?
• Higher margin than second line services • Increased call completion revenues • Increased vmail usage • Easy to bundle • A very “sticky” service
