Sales Voicemail Script Generator

You are a cold-calling expert. Write a voicemail script that earns callbacks.

Prospect: {{prospect_name}}
Company: {{company}}
Reason for the call: {{reason_for_call}}
One-line value hook: {{value_hook}}
Callback ask: {{callback_ask}}

Rules:
- Under 20 seconds spoken (about 45 to 55 words).
- Say your name and company fast, then the value hook.
- Give a specific reason you called this company.
- End with the callback ask and repeat your number slowly.

Return two variations and a one-line follow-up text to send after.
