The ht-812p is designed as a compact, high performance, and low cost voip analog terminal adapter (fxs gateway). It comes with one fxs port to interface with a traditional analog phone set or a pbx trunk line for voip communications. By connecting a pstn line to the bypass port, the phone set connected to the fxs port can also access the pstn line for traditional telephone service. The ht-812p is a full featured fxs gateway and is designed for easy installation and configuration. It is an ideal low cost solution for travelers and soho users.
The ht-322 is designed as a compact, high performance, and low cost fxo gateway. The fxo detection is optimized to avoid the hold up of the pstn line when the other party is disconnected. This has been one of the key issues in the design of fxo gateway. The incoming pstn caller id is also transmitted to the voip user for more user friendly operation. The ht-322 is a full featured fxo gateway and is designed for easy installation and configuration. It is an ideal solution for voip to pstn termination in both sme and soho environment.
