so this fax machine i have seems to be a piece of junk. Even when it was hooked up to a dedicated phone line it had problems with dialing, getting EASILY jammed, so i want to replace it. I think i found a good Multi Function Brother 7220 Model that seems like it will work good even has a laser printer, but i read a review on Staples.com and it said that the fax wont work well in an enviornment where its using the same shared line as the DSL. Is this going to be a problem with all fax machines sharing a phone line with a voip/dsL ? this is for work at my home office and I do use the fax daily to fax things up to my parents home office. what if i plug my fax machine into a splitter thing ?
