It may or may not. That depends on the number of faxes you receive.

Fax boards (Mainpine, Brooktrout) and fax modems (Multitech, US Robotics) are worlds apart. Fax boards are faster, more efficient, and more reliable. They also have onboard processors and do not use the resources of the computer. To be honest, fax boards are for people who send/receive a large volume of faxes on a daily basis. We used to go through a Ream/Half a Ream of paper of faxes daily. That's not including the ones we send out. So, a faxboard made a lot of sense to us. Before that we had a USR Fax Modem that simply could not keep up and had a lot of sending/receiving issues.

SBS Essentials has the Server 2008R2 core so everything you can do on Server 2008R2, you can do on Essentials. It's called the Fax Server role in the Server Manager, you simply need to add it. There's no software conversion involved. Mainpine engineered the PDF conversion into the driver so you will see it as a routing method when you set it up.

When sending out faxes, you use Windows Fax and Scan. Basically you choose the fax printer as if you would normally print a page in any application. The Fax is like a shared printer accessible by all computers. Use Fax and Scan directly is like an email interface. You have the To, Subject, Message, and Attachment fields for quick faxing.
