I want to create a voice dailing bot in python that calls on a list of numbers using a sip trunk and talks to customer in real time like real humans and ask them if they want to schedule their dental appointments in coming week or no? I want these calls to be automated and headless (not in a browser). Can I use AGI with pre recorded audios for this?
Welcome to the forums!
Yes, you can probably do this with Asterisk. There are a lot of good AGI commands available, as well as python libraries.
