Cablevision Surpasses 2 Million Optimum Voice(R) Lines

Nation's Most Highly-Penetrated Competitive Phone Service Continues to Win
Awards, Attract Customers and Surpass Milestones, Delivering Value,
Reliability and Advanced Features to Residential and Business Customers

BETHPAGE, N.Y., July 31 /PRNewswire-FirstCall/ -- Cablevision Systems
Corp., (NYSE: CVC) today announced that its award-winning Optimum Voice
digital voice-over-cable service this week surpassed 2 million phone lines in
service -- the latest milestone for a product that has attracted more than a
third of the homes passed by Cablevision's fiber optic network and a growing
base of business customers as well, as it has continued to win accolades for
quality and reliability. Just this week, Optimum Voice was named the top voice
over IP service for the fourth year in a row in PC Magazine's annual Readers'
Survey, while winning a fourth straight Readers' Choice Award. Optimum Voice
also received the highest rating in residential telephone customer
satisfaction in the Mid-Atlantic region for 2007 in a study by J.D. Power and
Associates.
"The response by residential and small business customers alike to the
value, reliability and advanced features of Optimum Voice has been
extraordinary," said Joe Varello, Cablevision's vice president of digital
voice product management. "We want to thank our customers for helping us
achieve this latest milestone -- more than two million phone lines in
operation across our service area -- as Optimum Voice continues to win high
praise and accolades, redefining expectations of how good a voice service can
be."
Cablevision offers small and medium-sized business customers up to 12
lines of Optimum Voice, up to four lines for residential customers, all
without the contracts or hidden add-on fees that are common among old-line
phone companies. Every line includes unlimited flat-rate calling across the
U.S., Canada and Puerto Rico, with a full suite of advanced calling features
included at no additional charge, including call waiting, caller ID, enhanced
voicemail, call forwarding and directory assistance.
Optimum Voice is available exclusively to Optimum Online(R) high-speed
Internet customers. The service includes unlimited calling across the U.S.,
Canada and Puerto Rico, and a superior array of advanced features like
enhanced voicemail, call waiting, caller ID, caller ID blocking (*67), call
return (*69), three-way calling and call forwarding, free directory assistance
(411), VIP ringing, find me, caller ID on call waiting, busy redial, anonymous
calling and anonymous call blocking -- all at no additional cost. The
service's "My Optimum Voice" web portal allows customers to easily activate
account features, listen to voicemail messages through any Web browser, review
and sort calling history and manage other settings.
Unlike "Internet phone services," Optimum Voice provides the security of
enhanced 911 access for every customer and provides a local number portability
option, so new customers who switch from other telephone companies can keep
their existing phone number. Optimum Voice service is carried over
Cablevision's fiber optic network, not the public Internet, and offers
customers a highly reliable voice service with superior value.
For customers who make international calls, Cablevision offers an
innovative flat-rate international calling plan, Optimum Voice World Call,
giving customers up to 250 minutes per month of calling anywhere in the world
from their Optimum Voice phone, including up to 30 minutes of calls to Cuba,
for a flat monthly fee of $19.95, delivering more value to customers than any
other international calling plan.
