Thanks Bert. Excellent advice as well. Nice screen shots. I should've probably included some.
As a side note for Rene, the reason why Bert has 2 IQFSP devices and 2 Fax Modems listed there is that he has the 2 line model. If you have the single line model which is the one in the recommended section, you should have 1 Fax Modem and 1 IQFSP Device listed. Make all modifications to the IQFSP device.
These things are workhorses. 2 Line Models should only be necessary if you are literally receiving faxes all day. They are amazing. My modem was never able to get over a 20 page fax. Always had issues with sending, receiving, etc. Fax boards are a different species. This thing can easily receive 100 page faxes without any issue.
