PacketCable-ready solution, Net2Phoneï¿½s VoiceLine will now offer providers
SIP-based hosted telephony services that can be sold to their residential
and SOHO customers in a bundle with their existing product set.
IT: How does this affect Net2Phoneï¿½s existing cable telephony
SH: Our VoiceLine SIP-based hosted solution complements our
PacketCable offering, allowing service providers to choose the type of
service they want to give their customers.
IT: How can cable companies benefit from the availability of these
SH: Cable operators now have a choice when determining how they go
about rolling out phone service to their subscribers. Net2Phone is the
only provider that can meet the needs of domestic and international cable
operators with any DOCSIS standard networks, as well as metropolitan and
remote customer franchises. By offering two tiers of service, Net2Phone
can conform to any cable operatorï¿½s particular marketing, technical,
financial, and operational needs.
Net2Phoneï¿½s PacketCable Managed Telephony solution empowers cable
operators to provide their subscribers with a service that resembles
traditional telephony in terms of service, quality, features,
functionality, and reliability. Its accompanying network management
toolset enables fully managed end-to-end VoIP cable telephony service,
guaranteeing quality from call inception through termination. Throughout
each point in the network ï¿½ the local cable HFC network, the IXC segment,
and the local termination ï¿½ Net2Phoneï¿½s PacketCable solution delivers
end-to-end guaranteed call quality, network availability, and service
Net2Phoneï¿½s VoiceLine utilizes SIP signaling, which empowers edge
devices, such as multimedia terminal adapters, to establish and manage
voice calls on all types of high-speed data networks. Net2Phoneï¿½s
VoiceLine architecture centralizes the call management, CLASS features,
billing and provisioning platform and enhanced services and distributes
the infrastructure required for interconnecting onto and off of the PSTN

to a Vonage or Packet 8?

replete with E911 availability, CALEA compliance, etcï¿½?

replacement-line service, including E911, and compliance with most CALEA

plugs into a broadband Internet connection to provide dial tone to
IT: What role does the rate of broadband adoption play in the
success of VoIP?
SH: Clearly, extending high-speed Internet access into the home is
a driver for more VoIP usage. The better the access, the better the
quality of the call.
IT: In your view, what is the overall state of the cable telephony
SH: The larger cable operators have already made considerable
strides in providing that the triple play of voice, video, and data
generates additional revenue and is a proven customer retention tool. We
hope to empower cable operators that have financial, technical, or
operational constraints to gain the same benefit from bundling telephony
as the larger operators.
IT: Do you see greater opportunity for VoIP over cable domestically
in the United States or overseas?
SH: The opportunities are fantastic both domestically and
internationally. We are focused on markets with the greatest broadband
