USA Based customer service and support @ 423-567-4888. Save thousands and increase your office's productivity with the Ring-u Hello Hub. Designed especially for small offices and businesses, the Hello Hub is easier to set up than most wireless routers. A Virtual Receptionist can professionally answer calls and route them to the person or department needed. Other features include an open/closed/holiday receptionist, as well as ring groups, and voicemail to email. This bundle ships with ten (4) Wifi and Bluetooth capable Executive phones. While some systems require multiple "base stations" for more than five lines or extensions, just one Hello Hub unit offers up to 20 lines (calls) and 50 extensions. The Hello Hub offers plug-n-play auto configuration for Grandstream GXP 1620/1625/1630/2130/2135/2160/2170 GRP2602/2614/2615/2616 + DP720/750 and WP820/822/825 phones. Fully operational in minutes. Mobile phone integration is simple. Simply use cell phones as extensions with or without iOS and Android apps. Texting directly from your system (web interface) using your primary business number is quick and easy. For even more utility, set up offsite land line phones as remote extensions. The integrated no contract VoIP service starts at $79.95 for 2 lines/calls and $24.95 per additional lines/calls. The service is charged by the line, not by the seat or the extension, which allows for customizable savings, with no contract. Founded on honesty and customer satisfaction, Ring-u offers industry-leading customer support and a 90-day 100% money back satisfaction guarantee.
