Transfer calls from a Custom API response

A Custom API step can now return a transfer instruction, and the agent acts on it during the call. The number does not have to be known when you build the agent, so routing can follow whatever your own system decides at that moment: the owner of an account, the next free person on a rota, a branch chosen from what the caller said.

Set it up on the Custom API action in the agent editor. The setup guide walks through the response shape and what happens when the transfer cannot be made.
