I am trying to do the same with an ASM400. I want to be able to call the phones hooked up to the FXS port by an extension number.
Lets say, i want to call from FXS 1 port (extension 10), to FXS 2 port (extension 11), and so on…
what do i need to do to make this possible ?
2) if i call from a outside gateway can i reach the phone on port 1 ?
3) how does one identify the ports to the extensions internally. (match them up)
4) if I have a standard pbx and i want to add a virtual line with dial tone ..do I use take the cable from the FXS port to the Panasonic trunk line ? or do i take the FXO port ?
thanks for your help
