Introduction

AudioCodes MP-20x series of analog Telephone Adapters are cost-effective, feature-rich
gateways, allowing the connection of ordinary POTS analog telephones or fax machines to
a Voice-over-Broadband (VoBB) service provider.
The MP-20x series is designed for the rapidly growing residential and Small Office/Home
Office (SOHO) voice-over-IP (VoIP) market. The MP-20x series typically connects to an
existing Broadband Internet device (Cable and ADSL modem, - depending on model), and
establishes a communications path with the service provider network through its IP uplink
connection. Supporting a rich set of subscriber calling features such as caller ID, call
forwarding, and call waiting, the MP-20x series maintains a uniform user experience when
migrating to VoIP services. In addition, the MP-20x series serves as a router with
capabilities such as DHCP, NAT, Firewall, PPPoE, PPTP and L2TP, supporting
connectivity of home PC networks.
The MP-20x VoIP Gateway is an all-in-one unit featuring (depending on model) a VoIP
adapter, FXS lines, FXO interfaces, Ethernet LAN interfaces (with an internal Layer-2
switch), and Ethernet WAN interface.
Utilizing AudioCodes' VoIPerfect™ core architecture, and gaining from its accumulated
experience in providing IP telephony solutions, the MP-20x series combines superior voice
quality and cutting-edge features for end users, such as T.38 Fax Relay and G.168-2004
compliant Echo Cancellation. Low bit rate vocoders (voice coders) can be used
simultaneously on all the telephony ports to save valuable bandwidth.
The MP-20x is available in the following models:
