Grandstream HT813 FXSFXO ATA gateway 1x FXS 1x FXO 2x 10 100 Mbps RJ45

Grandstream HT813

The hybrid analog telephone adapter (ATA) with integrated NAT router has an FXS port for analog telephone devices and an FXO port for connecting a PSTN line. It is designed for users looking for an analog to VoIP converter. Thanks to the integration of FXO and FXS ports, this hybrid ATA device allows remote calls to and from a PSTN line. Other advantages include support for a backup lifeline line (in the event of a power outage, the FXS port will be permanently connected to the FXO port) or a failover SIP server, which automatically switches to a secondary server if the main server fails. The adapter offers advanced telephone functions such as call forwarding, call holding, or caller ID display. You can also use three-way audio conferencing support or the fax-over-ip service (T.38 protocol). Exceptional voice quality is ensured by support for HD codec and QoS (Quality of Service). To make device management easier, you can use automatic provisioning within TR-069. For better security, to protect calls and accounts, TLS, SRPT and AES encryption technologies with a security certificate for a specific unit will take care of it.
