It provides 4 RJ11 FXO ports for connecting PSTN lines and 1 RJ11 FXS port for connecting an analog telephone or fax machine. This makes the HT841 ideal for businesses that want to integrate existing analog phone lines with an IP PBX such as the Grandstream UCM series.

The HT841 also supports T.38 Fax over IP, multiple voice codecs, failover SIP server functionality, secure provisioning and strong AES encryption. Its FXS port provides lifeline support, allowing it to be hard-relayed to an FXO port during a power outage.
