Voice

Voice, from the number inward.

A phone call has more moving parts than any other channel: a number, a route, a menu, a machine, a recording. These guides follow one call through all of them.

Answering calls

A number, an agent behind it, and what happens to the call after the caller hangs up.

Making calls

Campaigns and contact lists: what has to be true before the first call goes out, and the ceilings that decide how fast the rest follow.
