The Grandstream HT813 is a hybrid VoIP adapter that connects one analog phone or fax machine to SIP service while also linking to a PSTN phone line, making it suitable for homes or small offices that need both VoIP and landline connectivity.
Recommended For
- Home-office or small-office users who want to connect one existing analog phone to a SIP account while keeping a traditional phone line available through the FXO port.
- Users who need a fallback path for a connected analog phone: if the HT813 loses power or SIP registration, its lifeline feature can connect that phone directly to the attached PSTN line.
- Small-business or home-lab users connecting one PSTN line to a SIP system, such as an IP PBX, for routing calls between the analog line and VoIP extensions.
- Users keeping an analog fax machine in a VoIP setup who need an adapter that supports T.38 fax relay; compatibility with the VoIP provider and the receiving fax setup should be checked.
