Polycom VVX Phones Missing from EPM

This is my first experience with setting up my own phone server. I’ve installed PBX using the FreePBX 3.211.63-8 distro and everything is up and running.

I purchased EPM. I’ve checked in both OSS EPM and the official EPM and I only see the VVX 500 and VVX 1500. However, on this page: http://wiki.freepbx.org/display/FCM/Supported+Devices+in+EPM it says that the VVX 300 and 400 are supported. Should I just be choosing VVX 500 for those phones as well?
