Install was straightforward, and had the option to check for a newer build. There are options for the server, a remote fax monitor, and the Exchange 2000/2003/2007 connector. Setting up fax receiving, routing, and sending via SMTP to the FaxMaker server is clear and excellent directions are provided for any common Exchange & e-mail architectures. Support for Active Directory is a nice touch. Even without Active Directory, faxes can be routed to users via e-mail address. If you've ever used a fax client for Outlook, you'll know what to expect. I did find that the FaxMaker client was a bit better thought out and that it was easier to "get used to" than some I've used. Faxing from any application is standard fare through the use of the FaxMaker print driver.
Testing of configuration and use for Brooktrout boards, DID and FoIP were beyond the scope of this review, although from the thoroughness of the documentation I would expect no problems. If you haven't configured multi-channed fax or modem hardware or VoIP equipment before, that would be the more problematic aspect of the configuration for you anyway. I didn't have the chance or need to talk with their support team, and doubt I would need to, since the product was straightforward, worked well, and has excellent documentation.
