So I am trying to make the transition to Asterisk/Freepbx. However, I want to ensure my knowledge at least at a higher level is correct in terms of hardware/extra things is correct. I have a FXO card coming in so we can hook up analogue items such as faxes and so forth. However, beyond that would all we need is a FBX gateway with a DID number in order to make external calls/ receive incoming calls? This is of coarse ignore that this needs to be set up within asterisk itself. Let me know if I am missing something or if I don’t actually need something.
Also… this is for a small business set-up so any other pieces of advice would appreciated like should we get more then one DID number or should we get one DID number with x amount of channels? or really anything relevant piece of information you can add.
