FYI from Avaya website:
Hardware Requirements
BCMR Desktop Recommended Minimum PC Client Requirements:
Operating System: Windows 2000 (Server or Professional), Windows XP Professional or Windows 2003 Server.
Processor: Single-processor Pentium Only (Dual Processors are not supported).
RAM: 32MB.
CD-ROM Drive: Double Speed CD-ROM drive.
Serial Ports: One for an external wallboard (optional).
Parallel Ports:To attach a local printer (optional)
Note: The Server and Client PC hardware requirements have not changed in BCMRD R2.4, except for the support in the server of a hardware license key attached to a USB port as an option to the parallel port capability.
You'll need a lot more RAM than what they show here, surely that was suppose to be 320M. We have 500M so it's still not much.
