I am new to Twilio and OpenVBX. I had someone in my company setup a campaign that was auto dialing a list of numbers and things, and it would auto put them on a list if they called back, but now that person is gone and I was never shown how to setup these call list and things. I need someone who can help me with this so I can learn how to setup OpenVBX and actually utilize it considering I have spent some money and put credits into it.
