Suddenlink Communications said today that it now has more than 250,000 active phone lines serving residential and business customers, which is up from approximately 30,000 lines at the beginning of 2007, before the company expanded phone service to most of its markets. 

Suddenlink said its customers are now placing and receiving up to 6 million calls a day, about twice as many daily calls as the company’s network handled 14 months ago and six times as many as it did two years ago.

“Our phone service is increasingly popular, as more customers realize they can get the same, or in many cases better, quality of service than they’ve enjoyed in the past for substantially less money,” said Suddenlink chief operating officer Tom McMillin. 

Suddenlink’s phone service uses IP technology to transport calls over the company’s own private, managed IP-based network. As a standard part of its residential service, Suddenlink offers unlimited local and domestic long-distance calls, plus a set of popular calling features. 

Suddenlink also provides automatic access to the FCC-mandated Enhanced 911 system and is compatible with most modern alarm monitoring equipment.

Earlier this year, the company launched an enhanced business-class phone service for larger commercial accounts with more complex telephony requirements. 

Suddenlink, the nation’s eighth-largest MSO, serves 1.3 million residential customers and thousands of commercial customers in Arkansas, California, Louisiana, Missouri, North Carolina, Oklahoma, Texas, West Virginia and elsewhere.
