Don't let the smooth taste full you. Low cost phones over internet = poor service, many dropped calls, and down time due to Nuvio updates and short comings. Very frustrating trying to run a business with these interruptions. It seems alot of the independent reps that were selling Nuvio services have now switched to other providers.
Nuvio wants a credit card so they can automatically bill you each month. Rarely do they want to credit you for "down time" that experience throughout a given month. They mainly try to blame your internet provider, or your equipment. I had said provider out to my location consistently testing everything and all tests would check out ok.
My sales rep stopped selling Nuvio services and switched me to another provider. He called Nuvio and had the numbers ported to new provider and cancelled my account with Nuvio. Nuvio billed me for 6 additional months on my credit card. Even though Nuvio provided nothing in those 6 months. I was told by Nuvio that it had to be a written statement to close the account. Funny thing is my sales rep had Nuvio on a speaker phone in my office and he confirmed with Nuvio that the account was closed.
Very poor product and very poor customer service. My advice is to stay as far away from Nuvio as possible. Unethical company at best with a poor product.
