Cisco Systems' Linksys division and VoIP service provider Vonage have introduced a trade-in program for customers interested in upgrading their existing router for a Linksys Wireless-G Router configured with Vonage. Through July 23, customers can trade in their used router -- any brand, any model -- for a Linksys Wireless-G Router with 2 Phone Ports (WRTP54G) for free (after rebates) when they sign up for Vonage's broadband phone service. By adopting the strategy, Vonage is breaking the industry practice of simply giving away telephone adapters.

"As more Americans are moving to wireless networks, they can now easily configure their home networks by switching to Vonage, and immediately start getting more for their communications dollar," said Matthew Deatrick, Vonage's senior vice president of sales, in a statement.
