Cisco SPA8800 IP Telephony Gateway with 4 FXS and 4 FXO Ports

The Cisco SPA8800 IP Telephony Gateway is a multipurpose solution that small businesses can use to connect an on-premise IP private branch exchange (PBX) system to the public switched telephone network (PSTN), or connect a legacy time-division multiplexing (TDM) PBX or key system to voice-over-IP (VoIP) services. The Cisco SPA8800 provides a combination of four Foreign eXchange Office (FXO) and four Foreign eXchange Subscriber (FXS) ports to connect to existing analog phones, which helps protect and extend your existing communications equipment investments, too. The Cisco SPA8800 also has the capability to be configured as an FXO gateway for an Asterisk Open Source PBX providing a versatile solution when conditions favor an external device.

Cisco SPA3102 Voice Gateway with Router

Internet telephone service is now more accessible than before. Part of Cisco Small Business Voice Gateways and ATAs, the SPA3102 Voice Gateway allows automatic routing of local calls from mobile phones and land lines to Voice over Internet Protocol (VoIP) service providers, and vice versa. By first calling the local number on the SPA3102, you can reduce or eliminate long-distance charges altogether. If power goes out or Internet service is lost, calls can be safely redirected to a traditional carrier via the standard analog interface. Additional features of the Cisco SPA3102 include:

• One RJ-11 POTS (Plain Old Telephone Service) FXS port to connect an existing analog phone or fax machine
• One PSTN FXO port to connect to a Telco or PBX circuit
• Two 100BaseT RJ-45 Ethernet interfaces to connect to a home or office LAN, and an Ethernet connection to a broadband modem or router
• FXS and FXO lines that can be independently configured
• Secure encryption-based methods for communication, provisioning, and servicing
