Answer

Two different situations are possible:

a) No AI Agent is clocked in for the group at all.

The lead never becomes an AI candidate - it is dialed by the group's human agents like any regular lead. Nothing waits, nothing is skipped.

b) Bots are clocked in, but all of them are busy when the lead answers.

The answered lead is held while the dialer keeps trying to claim a free bot, for up to the group's available agent search timeout. During the wait the lead hears the group's Dropped Call Settings experience. If no bot frees up in time, the group's Predictive Dropped Call Action runs:

• Hangup: the call ends and is recorded as an AI drop.
• Playback: a goodbye message plays, then hangup (also an AI drop).
• Forward: the call is transferred to the configured destination (not a drop).

A busy-bots wait does not spill the lead to a human agent - human fallback is reserved for vendor failures (below). In practice the AI pacing dials to match free bot capacity, so this is a rare edge case rather than the norm.
