Photos: Touring the floor at VON

Vonage, which provides IP telephony service to consumers and small businesses, displayed its new portable Wi-Fi phones, which allow people to use their Vonage VoIP service when they're connected to any public Wi-Fi hot spot. The Vonage phones were on display at a booth hosted by Sonus, a "softswitch" maker that provides equipment to Vonage.
