It have examples of n-way calling, most via conference.

Answer 2

Consider dropping both calling and called parties (customer & agent, respective to how you're operating) into a conference call, and then!

...Go and originate another call (with AMI or a call file) that's operating from a new context/extension/proirity and also drop this originated call into the conference.

I haven't tested this with DTMF input into a call prompt -- But, I have played automated messages to both calling and called party in a conference using this technique.

The caveat may be that both calling and called parties will have control of the prompt. Which may or not be relevant to your use case.
