Broadband Access and the Role of VoIP
>
With the deployment of more broadband access it is inevitable
that voice will be treated as another application on the data
network
•
•
•
>
SIP as the enabler for VoIP
business will establish private voice networks utilizing their data
networks - IP PABX
residential will use messaging services (MSN, Yahoo, AOL etc) as
well as long distance bypass offerings
Take ownership of the VoIP service offering
•
•
•
•
integrate the voice offering with the Internet service
provide the SIP servers, ENUM, access to the PSTN
control the quality of service beyond Internet based VoIP
integrate other value added services
