I have an 8-port Unity installation with both Exchange and Unity on one server. I have only 60 user so I've been told that this type of installation is acceptable. I want to install Active Fax on a separate server; however I have only one key. Do I have to purchase this type of configuration separate or ? Also, I am interested in knowing where I can obtain a list of supported fax boards - I understand that a larger variety is supported when no voice boards are involved.<br><br>
