Description

8 FXS VoIP Gateway Description

Product Introduction

The HT-882P VoIP gateway is designed as a compact, high performance, and low cost VoIP Analog Terminal Adaptor (FXS Gateway).  It comes with 8 FXS ports to interface with traditional analog phone sets or PBX trunk lines for VoIP communications.  The HT-882 is a full featured FXS gateway and is designed for easy installation and configuration .It supports the two most widely used Open VoIP Standards (SIP and H.323).  This allows the HT-882 to interoperate seamlessly with softswitches or IP PBXs made by various vendors.  Its high performance offers toll quality voice, flexible networking, and feature-rich call functions.  It is an ideal low cost solution for SME environment where multiple lines are required.

 

Key Features Static IP support Switch mold support support DHCP,PPPOE Open Standard VoIP Protocols (ITU H.323 V4 and IETF SIP V2) Two 10/100 Ethernet for WAN / LAN connections Peer-to-Peer IP Calls Speech quality ensured by QoS at the Ethernet and IP layers and comprehensive jitter buffer Line Echo Cancellation VLAN and QoS support NAT Transversal and Router functions Voice prompts, HTTP Web, Auto Provision support for configuration and updates Highly stable embedded Linux operating system in high performance ARM 9 Processor

Basic Features Eight RJ-11 FXS port for traditional phone set or PBX's trunk line LEDs for Power, Ready, Status, WAN, PC, FXS Call Forward, Call Hold, Call Transfer Dial Plan Caller ID 3 times re-password Billing support Keyboard setting IP voice enrollment

Enhanced Features Dynamic selection of codec Advanced jitter buffer Automatic traversal of NAT and firewall VLAN / Qos Router Echo cancellation for Speakerphone Comfort noise generation (CNG) Voice activity detection (VAD) Auto provisioning (requires auto provisioning server) On line firmware upgrade Multi-language support: English and Chinese
