The minimum requirements to support the card are: 800MHz processor, 128MB RAM, Linux kernel 2.4.X or 2.6.X (2.6.X recommended). However, IP PBX system requirements are dependant on the open source telephony software being used and on the number of simultaneous calls to be supported. Two examples are provided in the table below:


	Asterisk® (home use)	Trixbox® (8 calls)
Processor	Intel PIII 500MHz	Intel Celeron D 2.4 Ghz
RAM	128 MB	256 MB
Hard Disk Space	2 GB	80 GB EIDE
