I am new to Asterisk and from what I have read in the documentation and these forums it sounds like exactly what we need. We have 3 analog lines coming in and 8 analog phones. Will Asterisk work with this setup? I have seen a lot of information with IP phones with analog PSTN, but nothing entirely analog. I am planning on using 3 X100P FXO cards to connect to the PSTN and a Grandstream GXW-4008 8 port FXS Analog SIP gateway to connect the Asterisk box to the analog phones. I am sure the FXO cards will work, but am not so sure the GXW-4008 will work. Does anyone have experience with this gateway, or have any recommendations on the setup?
