So for one, business lines almost always have public IPv4. Even then, there are a myriad of providers that provide a solution even behind NAT (also, they probably have public IPv6 space). Any technology provider that could provide AI chat over telephony could also take care of the data connectivity path on their behalf. Anyone that would want to self-host such a solution would certainly have inbound data connectivity also solved. I just don’t see a scenario where a business can have AI telephony but somehow can’t have inbound data access.

So you have a camera on a logbook to get the human input, but then that logbook can’t be a source of truth because the computer won’t write in it and the computer can take bookings. I don’t think humans really want to do a handwritten logbook anyway, a computer or tablet ui is going to be much faster anyway.
