The problem

Why CAC math collapses on volatile telecom.

CAC volatility

Per-minute billing breaks acquisition math

Subscription CAC is calculated against a fixed customer LTV. If telecom is variable, your unit economics swing every campaign.

Win-back at scale

Churned-customer outbound burns CLI

Aggressive win-back campaigns burn shared CPaaS pools fast. Retention contact rates collapse.

Brand trust

"Spam Likely" on your brand calls

Existing customers seeing "Spam Likely" when your brand calls is a retention disaster.

The fix

Three concrete shifts.

Flat per-seat

Predictable CAC math

Pay flat per concurrent channel. CAC math holds across heavy and light campaigns.

STIR/SHAKEN A

Brand calls pass attestation

Every US/CA outbound signed end-to-end. Your brand is not flagged on the existing-customer handset.

CLI rotation

Numbers stay clean for retention

Managed rotation across the pool keeps individual CLIs from getting flagged in win-back campaigns.
