Verizon is readying a marketing attack against cable VoIP and Internet-based VoIP.

Verizon said that when it informs consumers about “the astounding reliability of Verizon’s custom-built network,” the number who say they might subscribe to cable or Internet VoIP drops.

In other words, Verizon believes the success Verizon Wireless is having with its commercials that play up the reliability of its cellular network looks like it can be carried over to other Verizon phone products.

“Parity is something cable competitors can’t claim, and they know it,” said Verizon VP of marketing Judy Verses. “Our mission is to highlight this for customers, because it matters to them.”

Verizon’s new advertising campaign will consequently start hammering on service quality. The new commercials depict customers who experience a sense of security when “home alone with the kids,” “when there’s an emergency,” “no matter what the weather,” and “when the lights go out,” followed by the tag line, “It’s the network.”
