Sipura-3000 FXO port and Asterisk
Using an Analog Phone Line with Asterisk via SPA3K
This article describes how to set up a Linksys Sipura-3000 adapter and Asterisk for making and receiving calls on a conventional analog telephone line (POTS) via the Linksys adapter's FXO port. The configuration example in this article assumes that the Linksys adapter and Asterisk are both on the same LAN.
Note that it is not recommended to connect the FXO port of Linksys adapters to the public telephone network in countries where Linksys does not officially support it. Doing so may cause a fault at the public telephone exchange and prompt the telephone company to disconnect your line. Please consult Linksys whether it is safe to use the device in your country of residence.
