Grandstream's IP voice & video products offer the best price-to-performance point in the industry. We are pleased to announce that we have completed interoperability testing with Grandstream's engineering team, and will support Grandstream's entire product line under our highest (Certified) interoperation category. Supported devices include the HandyTone ATA (analog telephone adapter) models HT502, HT503, HT701, HT702 and HT704, enterprise analog IP gateway models GXW4004, GXW4008 and GXW4024, and the Grandstream UCM6100 series IP PBX Appliance.
We are no strangers to the Grandstream product line, and it's no accident they are among our earliest Certified interoperation partners. The Telephony Depot division of our company began selling Grandstream products in 2006, and is currently one of Grandstream's largest North American distributors. Their products include a mature T.38 FoIP implementation that we are happy to recommend to our customers, and our own support team enjoys direct, priority access to senior engineering resources within Grandstream should we need escalate any issues to the manufacturer.
