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 intended 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 failure, 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 telephony features such as call forwarding, call holding, and caller ID display. You can also use three-way audio conferencing support or fax-over-ip ( T.38 protocol). Exceptional voice quality is ensured by HD codec support and QoS (Quality of Service). To facilitate device management, 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.
