The 2-Port Analog Telephone Adapter (ATA) with integrated Gigabit NAT router enables you to create high-quality and manageable IP telephony solutions for home and office environments. Built on cutting-edge SIP ATA/gateway technology, this powerful ATA offers exceptional voice quality across a variety of application environments, strong encryption with a unique per-unit security certificate, auto provisioning for mass deployment and device management, and outstanding network performance. The adapter offers advanced phone features such as call forwarding, holding calls, or notifying you of incoming messages. You can also use the support of three-way audio conferencing or fax service so-called fax-over-ip (protocol T.38). For better security, for the protection of calls and accounts, you get support for TLS and SRPT encryption technologies. If you use the device in conjunction with the Grandstream UCM series, Zero Configuration provisioning will make your work easier.
