Ok, I am brand new to the concept of doing my own PBX.
First: What are the system/hardware requirements for a PC running the freepbx distro?
Second:
What services do I need to buy? I know I need a DID, and trunk? I see the ad for unlimted for 24.99 but wondering if there is something cheaper out there. (I may not need unlimited).
There’s no right answer on the hardware requirements, but just about any modern PC that can run windows 95, 98, ME, XP, Vista, or 7 will work just fine. A lot of people are using atom powered systems (i.e., netbooks). You can find a very active forum for hobbyists at pbxinaflash.com.
If you want to make outgoing calls, you can subscribe to a SIP trunking service, or you can connect a standard telephone line to your system using an FXO device such as the Grandstream GXW-4104 or the OBI 110.
If you choose a SIP Trunk service, you’ll need a DID (a phone #) if you want to receive incoming calls. You don’t need a DID if you only want to make outgoing calls.
