[Asterisk-Users] HELP - How Do I Separate incoming channels from the others on a PRI

[C F]

This is something that you wouldn't have any control over in most
cases. Your provider is the one that is sending the lines over the
whole PRI, they don't and shouldn't care about which channel it comes
over, they would use some system like gGrR that you can use in
Asterisk to send it to the next available channel, but not over a
specific one.
For your problem the easiest workaround would be to have extensions
setup in extensions.conf for your fax numbers, and use the setgroup
checkgroup apps to make sure that you don't use more than 3 channels
at onece for the 4th channel you can use the Busy or congestion app to
the PRI so that the caller gets a busy or circuit busy tone.
