Towerstream, one of the companies I have written about in the past has jumped into the already frothy VoIP waters. It has launched a beta version of consumer VoIP service which allows folks to make VoIP calls from WiFi hot spots, which are then back-hauled over company’s fixed wireless network. The early trial of the service was conducted in Middletown, Rhode Island. The company will launch a public beta in New York city, and consumers can sign-up here.   Beta users will be able to log onto the website to get up-to-date information as to where the service is available.  Users with any VoIP WiFi-enabled device or notebook will be able to utilize TowerStream’s network for free and make phone calls. Now the details in the press release are sketchy and I have pinged the company for further details. Stay tuned!
