Connect to Amazon Connect over Public Internet

We have a lot of clients who want to terminate calls into Amazon Connect over the public internet by just sending to a public endpoint, similar to how Genesys can take calls in via a hostname.

This is done as opposed to the traditional PSTN which can be expensive, is this a possibility now or in the future?

I created a test account to look but couldn't see any options and I also couldn't see anything in the help docs.

Perhaps in the future we would do this via VPN and potentially encrypted, but not required for both of those options for now.
