Slide 2
Purpose

Determine customer acceptability of IP-based
communications services
– Paradigms, features, functionality of Network (IP network), Services
and OSS
– Targeted at small-to-large businesses
– Services included:
• IP Telephony: BI-direction dialing (on/off net) with public/private dialing
• Desktop Services features, including IP Phones
• Voice messaging

Technology learning
– Implement solutions directionally consistent with NGN goals
– Not intended to be long-term service platform
– Ask questions, try technology and apply learning to long term
architecture for network, services and OSS

Slide 3
Strategies
Customers
 Customer
Selection
– 10 to 15 locations, 30% to 40% of customer site traffic on
the trial
– Will allow some reduction of features
– Willing to turn off the service at end of trial
 Internal
 Focus
users first, then external customer(s)
on learning about customer experience and
acceptability

Slide 8
Security
Current Strategy:

Use IPSEC AH (authentication header) with IKE (Internet Key
Exchange) between our “known” systems, including SIP servers and
gateways

Use SIP sender authentication and message integrity for mobile clients
Long Term Strategy:

The long-term model will require development of an effective public key
infrastructure and the use of X.509v3 (or newer) certificates
Issues:

IPSEC is relatively new and does not address mobility

No public key infrastructure in place today
