Purchase of the Linksys model number, which costs about $130, is required; then Vonage will distribute rebates to people who sign up for its phone service and trade in old wireless routers, Vonage said.
A Wi-Fi access point, which showers 300-foot-long zones with wirelessly available Internet access, isn't necessary to use VoIP; rather, any wired cable modem or digital subscriber line will do.
Still, Wi-Fi makes aservice more attractive because subscribers can make calls from anywhere in a home or office, rather than being limited to just a few phones outfitted with special adapters.
With the new tactic, Vonage is going beyond the standard practice of giving away telephone adapters required to make VoIP calls using regular home phones.
"As more Americans are moving to wireless networks, they can start getting more for their communications dollar," Vonage said in a statement.
