There are many "well it depends here" but lets start with this. The correct ports to open are TCP 5566, UDP 5567, UDP 5004, UDP 5005. From here it depends on version of endpoint software and version of system. Is this a 5000 or Axxess? Is it running in ITP mode or SIP mode? If you are a new version of Axxess or 5000 you can turn on Automatic Nat Traversal. But to start with open the correct ports listed above.

I've opened up ports 5004, 6004, 5566, and 5567 on our Cisco PIX firewall (in the office), as well as the on the remote router. Any help pointing me in the right direction would be much appreciated.
