My PBX Server is built out of an old converted HP Thin-Client, it is configured as follows:
- 1Ghz AMD Geode CPU (Athlon T-Bird based)
- 512MB RAM
- 8GB Compact Flash Card
- Onboard Realtek 10/100 NIC
- PCI Riser Chassis.
- PCI T1/E1 card (trunking with Definity PBX)
- TrixBox 2.6.1 (newer versions seem to break software echo canceling).
