Linksys SPA 3102
Analog Calls Routed over the Internet
Internet telephone service is now more accessible than before. The SPA 3102 Voice Gateway
is a part of Cisco Small Business Voice Gateways and ATAs. It allows automatic routing of
local calls from mobile phones and landlines to Voice over Internet Protocol (VoIP) service
providers, and vice versa. Reduce or eliminate long-distance charges by first calling the local
number on the SPA3102.
Calls can be safely redirected to a traditional carrier via standard analog interface in the event
of power loss or Internet access is unavailable.
