Unfortunately, AWS does not have answering machine detection capabilities that are very robust.
Meanwhile, you can use what they just introduced to the market (link).
It’s only going to get better from here.
However, we are working on a solution to leverage the AMD capabilities of an Asterix server (which we use for faxing via Amazon Chime anyway) for this purpose.
This section will be updated later.
This is a beta feature and will be beta for a while.
Meanwhile, there’s one solution proposed here 0x4447/0x4447_product_answering_machine: ☎️ An automated answering machine build on top of Amazon Connect that you can consider.
I have not tested this out. YMMV
