Tandem agents hold a conversation and act on what the other person says. One agent
can answer phone calls, chat on your website through an embeddable **chat widget**,
or do both — the agent's own **Channels** setting decides which. You configure an
agent's persona and behavior in **Voice Agents**, and give it facts to draw on by
attaching a knowledge base. **Contacts** is a separate list of the people your
organization talks to, with the fields you define on them. An agent set to recognize
its callers matches a call to one of those records, is told who is on the line, and
can write back what it learns.
