flexfax: Routing Faxes?

[Michael Dorin <mad@puma.chaski.com>]

I am sure this has been covered before, but I didn't see too much
in the archives.  (I did look, believe it or not)
Please let me know if I needed to search on a better keyword.  

Is it possible to use the TSI to route faxes?  I see you can use it
to reject junk faxes, but is it possible to use it as a routing aid?

Has anybody used a dialog or otherboard as a gateway?  Could you have
one board in the system answer a line, give a second dialtone, collect
digits, receive a fax, foward it to another system on the internet,
have it use hylafax to dump it out based on the gatered digits?

Any help would be appreciated.  Once again, I am sorry if I am hitting
a topic that has already been discussed..
