Overview
ƒ Challenge
Reduce the costs of long-distance voice calls, especially to
external international destinations
ƒ Solution
Use Tail-End Hopoff (TEHO) in more locations and implement
world-region call routing
ƒ Results
Initial cost savings of US$900,000 and future cost avoidance
of US$4 million annually
ƒ Next Steps
Identify more sites where TEHO and regional routing might
reduce costs

Challenge
Reduce Expenses for Long-Distance Calls
ƒ Recession in 2008-2009
prompted review of all
areas for potential cost
savings
ƒ Earlier TEHO strategy
had not been reviewed
in a long time
ƒ No formal process or IT
team in place to analyze
calling patterns and
costs against network
design

Solution
TEHO and Regional Routing
ƒ Implement TEHO routing in more sites
Carries long-distance calls on
the WAN to nearest Cisco office
“Hops off” to a local PSTN
circuit for completion
Based on intelligent routing in
Cisco Unified Communications
Manager and Cisco IOS Gatekeeper
ƒ Create new regional routing
hub in Amsterdam
WAN carries calls for partial
distance
Takes advantage of differences
in service provider prices
Alternative for sites where TEHO
is not allowed or cost-effective

Results
Cost Reductions and
Avoidance
ƒ Initial cost savings of
US $900,000 for new
TEHO sites
ƒ Future cost avoidance
of at least US$4 million
annually
ƒ Better able to identify
additional cost savings,
routing efficiencies

Next Steps
Monitor and Evaluate
ƒ Identify more sites for TEHO and regional
routing as justified by calling patterns and costs
