The Grandstream HT813 in depth

Hybrid FXS and FXO in one compact box

The HT813 integrates an FXS port and an FXO port so a single analog phone or fax can use VoIP while a PSTN line remains available. Remote users can make calls to and from the PSTN line through the HT813, and the FXS port is hard-relayed to the FXO line in a power outage.

Secure, easy to provision

Dual 10/100 Mbps ports with an integrated NAT router, T.38 fax, failover SIP server support and HD voice quality make the HT813 a practical upgrade path. TR-069 and AES-encrypted provisioning, TLS and SRTP give service providers secure, automated deployment.
