[Asterisk-Users] * fax reliability between ISDN PRI and FXS ports

[cguy at bigpond.net.au]

I plug my fax machine into a Grandstream ATA286 (No T.38).  Works fine for me and has done for the last year.  I can send and receive 40 page faxes without issue.  The ATA286 is located on the same LAN as the Asterisk.
