Horizon 1: Application Convergence
Applications and call control transition to a SIP core
Primary line applications integrate with enhanced service applications to create business
communications solution sets
 Conferencing, unified messaging, and contact center
End points interact via media gateways as IP edge and end points Majority of end points still
interact via IP / PSTN gateways
Wireless and wireline networks still independent of each other
Service providers deliver incremental value to their customers while end users obtain greater
productivity and simplicity
Marketers are moving away from wireless and wireline to business and consumer

Horizon 2: Network Convergence
Integration of wireless and wireline networks leveraging SIP core
Single identity or phone number possible across wireless and wireline networks
Can be marketed as stand alone wireless or integrated communications
End points are either TDM and/or IP
Messaging services ubiquitous across end points
Leverages IP routing core
Service providers able to offer bundled solutions while providing integrated and
universal messaging, billing, and feature set

Horizon 3: End Point Convergence
Ubiquitous IP environment
Wireless and wireline end points are all IP based
Directly interacts with native IP-based application servers
Access provided by reliable IP-based wireless last mile network
Will be initially launched in campus environments
