The 724 number will be my fax number. This will be handled in a slightly different way than most services. Usually, a fax number is a physical fax macnine which will consume paper for incoming faxes, or an efax server. I will be doing a combination of both. My SIP provider supports the ability to take in fax calls, convert the fax into a .pdf file, and allow me to view that file online. I can decide to save or print it. The SIP provider does not support outgoing e-faxing though. With that in mind, my printer which can also serve as a fax machine will have an ATA for outgoing faxes, and the fax line will have its own sub-account in my account. The fax will plug into the ATA, and the ATA will plug into the LAN. I can then send outgoing faxes using the minutes that will be available to my plan that I would have. This keeps things simple, and to the point. It will also save me paper since I don’t have to print SPAM faxes.
