You may find 4 port fax card via google but it's a long shot. I really doubt your going to be able to get a license for the voicemail either.
I have a 16 port 10.5 T3 server with fax card and licenses that I removed from a Telrad 1000 I would be willing to part with, it has 50 seats of UM also.
All you need is 2 ONS2 cards and some MIMs and you would be ready to go. If remember correctly it has a SMDR license also.
