Cisco SPA3102 VoIP Gateway - 1 x 10/100Base-TX WAN, 1 x FXS , 1 x FXO , 1 x 10/100Base-TX LAN
The Cisco SPA3102 VoIP Gateway features the ability to connect standard telephones and fax machines to an IP-based data network, with the additional benefit of an integrated connection for legacy telephone network "hop-on, hop-off" applications. SPA3102 users will be able to extend the use of their broadband phone service by automatically routing local calls from mobile phones and land lines to voice over IP (VoIP) service providers, and vice versa. If power is lost to the unit or Internet service is down, calls can be redirected to a traditional carrier via the FXO interface.
