[Asterisk-Users] * to Cisco router with FXO's via SIP

[Henry Devito]

FXS (Foreign Exchange Station) provide dial tone.  They are the station
side.  FXO (Foreign Exchange Office) Accept Dial tone from a analog phone
line.  FYI Here is a working config for using FXO ports in a Cisco router to
connect to asterisk.

? It's got FXS's on it. I get confused by that. So that means it does
VOIP to analog. Not analog to VOIP? Arrgghh

So I guess I will need a Digium card FXO or something.
