Having a spare Mini-ITX, I have decided to make this into a TrixBox IP PBX.
It will have:
1 analog trunk in/out from the StarHub Digital Voice.
2 Digital VOIP trunks in/out from pFingo
http://www.pFingo.com S$12/year per line.
The Hardware.
This is the mini-ITX that I have. It is an ITOX G5M100-N with a 1.7 Pentium M Centrino. 1GB DDR 400 RAM. 40GB HDD. Slim CD Drive for loading the OS.
The X100P single channel analog input/output card will be mounted on a riser provided by the Morex 2699 case.
As you can see, the X100P is actually a fax/modem card but not all fax modem cards can be used. I was fortunate to find through the used racks of 4th floor of SLS the cards that were compatible.
This is the Motorola 62802-52 fax modem card....
