Query: Got a problem here

I purchased the fax machine on the internet for the purpose of making it my personal fax machine for home use. I have internet phone service and it seems that this fax machine doesn't do too well in the digital world. Tech support told me that sometimes it will work and sometimes not! Nowhere in the sales process was I informed about this little problem. Not even in the packaging that came with the machine. Not a happy guy.
