Product Overview
Developed for small businesses, the Cisco®
SPA8800 IP Telephony Gateway (Figure 1) adapts to the needs of businesses
that maintain their own on-premise IP private branch exchange (PBX) or that
want to add voice over IP (VoIP) to their legacy time-division multiplexing
(TDM) PBX or key system. The SPA8800 can be configured to be a FXO gateway
for an Asterisk open source PBX, providing a versatile solution when
conditions favor an external device.
Powered by industry-leading VoIP technology from Cisco, the SPA8800 is
designed with a solid hardware casing and contains many standard features,
including four RJ-11 FXS and four FXO ports, a 10/100BASE-T RJ-45 Ethernet
interface to connect to either a router or multilayer switch, and an
auxiliary port for local administration. The gateway also includes a single
multiport RJ-21 50-pin connector, offering an alternative connection choice
for FXO and FXS ports when deploying the gateway in varied environments.
The SPA8800 features a high level of security by implementing state-of-the-art
technologies to provide standards-based encryption protocols (Session
Initiation Protocol [SIP] over Transport Layer Security [TLS], Secure Real
Time Transport Protocol [SRTP], and HTTPS/SSL). The gateway"s provisioning
capabilities give service providers a secure mechanism not for only remotely
managing the device, but also for installing software upgrades without
interrupting service and obtaining performance measurements and
troubleshooting information.
The Cisco SPA8800 is an affordable IP telephony gateway solution that is
ideal for small business environments that have VoIP service and also
require a connection to the public switched telephone network (PSTN). It can
be used with existing analog telephones and teleconferencing equipment,
enabling small business customers to protect and extend their investments.
Features
•
Toll-quality voice and carrier-grade feature support: The Cisco SPA8800
delivers clear, high-quality voice communication in diverse network conditions.
Excellent voice quality in a demanding IP network is achieved via the advanced
implementation of standard voice coding algorithms. The SPA8800 is interoperable
with common telephony equipment such as voicemail, fax, PBX, and interactive
voice response systems.
•
Large-scale deployment and management: The Cisco SPA8800 enables service
providers to provide customized services to their subscribers. The gateway can
be remotely provisioned and supports dynamic, in-service software upgrades. A
highly secure profile upload saves providers the time and expense of managing
and preconfiguring or reconfiguring customer premises equipment (CPE).
•
Ironclad security: Cisco understands that security for both end users and
service providers is a fundamental requirement for a solid, carrier-grade
telephony service. The Cisco SPA8800 supports highly secure, encryption-based
methods for communication, provisioning, and servicing.
