# Phone Numbers and Rotation Logic

> Learn how Callaro assigns numbers, rotates pools, and preserves caller identity where continuity matters.

# Number strategy is part of call performance.

Callaro treats phone numbers as an execution asset, not just a transport detail. Number health, geographic fit, spam exposure, and contact continuity all directly influence pickup rates and conversation quality.

  <Card title="Rotation" icon="refresh-cw">Spread outbound traffic across an approved pool so one number is not overused during high-volume execution.</Card>
  <Card title="Sticky assignment" icon="link-2">Keep the same number attached to the same contact or account when consistency improves answer likelihood and trust.</Card>

<Warning>
  If a number becomes spam-flagged, remove it from active high-volume traffic quickly. Let the campaign continue on the healthy pool while your operations team investigates remediation.
