Almost a year with the service and support has been always timely. I get responses in less than 24 hours and as soon as 45 minutes for some requests that I post to the support page. My calls are clear on solid connections as they should be, and the bandwidth needed for the calls is less than 1Mbps from my experience using 4 phones in a remote office with a speed of 1.5 Mbps down and 0.5 Mbps up. It's a good service to have locally.
