The Cisco SPA122 is an analog telephone adapter with a built-in router: it connects existing analog phones or fax machines to a VoIP service provider and provides an extra LAN connection. Cisco's data sheet lists two RJ-11 FXS phone ports, one WAN and one LAN 100BASE-T RJ-45 Ethernet port, and a reset button. Each phone line can be configured independently. Cisco gives ring voltage of 40 to 90 Vpk, ring frequency of 20 to 25 Hz and a maximum ringer load of five REN per line. Fax is handled by tone-detection pass-through, G.711 pass-through, or real-time T.38 fax relay, which Cisco notes depends on the fax machine and the network. Configuration is through a web-based utility with password-protected administrator and user access, and provisioning supports HTTPS with a factory-installed client certificate. Power is 5 V DC at up to 2.0 A from an external 100-240 V adapter, and consumption is 5 W. Cisco lists the SPA122 under end-of-sale and end-of-life products. Fit check: confirm the VoIP provider supports the SPA122 and the number of analog lines needed is two or fewer.
The SPA122 connects analog phones or fax machines to a VoIP service and adds a router; other Cisco VoIP hardware is in VoIP (Cisco).
