Product Overview

AudioCodes' Mediant 800B Gateway and E-SBC (hereafter referred to as device) is a
member of AudioCodes family of Enterprise Session Border Controllers (E-SBC), enabling
connectivity and security between small medium businesses (SMB) and service providers'
VoIP networks. The device provides SBC functionality as well as voice-over-IP (VoIP)
media gateway functionality. The device offers enhanced dialing plans and voice routing
capabilities along with SIP-to-SIP mediation, allowing enterprises to implement SIP
Trunking services (IP-to-IP call routing) and IP-based Unified Communications, as well as
flexible PSTN and legacy PBX connectivity.
The device is designed as a secured VoIP platform. Enhanced media gateway security
features include, for example, SRTP for media, TLS for SIP control, and IPSec for
management. A fully featured enterprise-class SBC provides a secured voice network
deployment based on a Back-to-Back User Agent (B2BUA) implementation. The SBC
functionality provides perimeter defense for protecting the enterprise from malicious VoIP
attacks; mediation for allowing the connection of any PBX and/or IP PBX to any service
provider; and service assurance for service quality and manageability.
The device offers call "survivability" solutions using its Stand Alone Survivability (SAS) or
Cloud Resilience Package applications, ensuring service continuity to enterprises served
by a centralized SIP-based IP-Centrex server or branch offices of distributed enterprises.
Call survivability enables internal office communication between SIP clients in the case of
disconnection from the centralized SIP IP-Centrex server or IP-PBX.
The device supports 1+1 High Availability when deployed with two devices, each
connected to a different network (in the same subnet). In case of a network failure in one
network, a switch over of traffic to the standby device occurs.
The device provides an integrated Open Solution Network (OSN) server platform that can
host a variety of third-party applications such as IP PBX, call center, and conferencing
applications.
The device supports various telephony interfaces, available according to model (refer to
the Release Notes):

Up to 12 Foreign Exchange Station (FXS) port interfaces. This is used for connecting
legacy telephones, fax machines, and modems to the IP network. The FXS interfaces
also support an analog Lifeline, enabling an FXS port to connect directly to the PSTN
upon power and/or network failure.

Up to 12 Foreign Exchange Office (FXO) port interfaces. This is used for connecting
analog lines (PBX or PSTN) to the IP network. When deployed with a combination of
FXO and FXS interfaces, the device can be used as a PBX for small office home
office (SOHO) users, and businesses not equipped with a PBX.

Up to 2 E1/T1 port interface over single copper wire pair, supporting Transparent,
CAS and ISDN protocols. The device supports various ISDN PRI protocols such as
EuroISDN, North American NI-2, Lucent™ 4/5ESS, Nortel™ DMS-100 and others. It
also supports different variants of CAS protocols for E1 and T1 spans, including MFC
R2, E&M immediate start, E&M delay dial / start, loop start and ground start.
