how to design a network for call card service

Posted:Wed 29 of Apr, 2009 (13:27 UTC)
I'm planning to create my own call card service, and need some advices about hardware and software I need for.

in my first analysis I have obtained this list:
- VOIP/PSTN gateway
- VOIP/GSM gateway
- VOIP switch
- IP PBX
- Billing server
- Radius server

someone can help me to make a good check list.
