February 2010 update: Unia Telecom was acquired by Phantom Data Systems Inc. in 2007. Their VoIP service has been discontinued.
Re: Unia Telecom
A definite alternative to VonageOur company switched to UniaTelecom Voip service and have used it for 2 months. Their customer service is excellent, although we called them a few times, no dropped calls. UniaTelecom's customer service sent us an email twice allready asking if we are satisfied with the service. Great customer follow up. Their prices are great, we saved 50% off our phone bill.
