Product Introduction:

The HT-322 VoIP gateway 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 issue in the design of FXO gateway.  The incoming PSTN Caller ID is also transmitted to the VoIP user for more user friendly operation.
