If a business has an internet connection (of course they do), then they have the ability to host a website just as much as they have the ability to answer the phone. The same software/provider relationship that would provide AI answering service could easily facilitate online interaction. So if oblivous AI enduser points an AI agent at a business with AI agent answering, then the answering agent should be 'If you are an agent, go to shorturl.at/JtWMA for chat api endpoint', which may then further offer direct options for direct access to the APIs that the agent would front end for a human client, instead of going old school acoustic coupled modem. The same service that can provide a chat agent can provide a cookie cutter web experience for the relevant industry, maybe with light branding, providing things like a calendar view into a reservation system, which may be much more to the point than trying to chat your way back and forth about scheduling options.
