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.
