Service Level Agreement

Our commitment to your uptime

What you can expect from us, how we measure it, and what we do if we miss.

Service credit calculation

If we miss the uptime target for your support level in a calendar month, you’re entitled to a service credit, added to your credit wallet, worth a share of that month’s voice and number charges:

  • 0.1% to 1.0% below target — 10% credit
  • 1.0% to 2.0% below target — 25% credit
  • More than 2.0% below target — 50% credit

Credits are not issued automatically. Email billing@callsathi.com within 30 days of the incident with the affected month and we’ll reconcile.

What’s not covered

  • Scheduled maintenance windows announced at least 7 days in advance.
  • Issues caused by third-party telephony / WhatsApp / payment providers when the upstream service is itself reporting an outage.
  • Customer-side misconfiguration (wrong API key, mis-routed DNS, deleted phone number, revoked Meta access token).
  • Force majeure events: natural disasters, government action, war, cyber-warfare campaigns.
  • Bonus credits added by our team (including any earlier welcome credit) and trial usage do not carry uptime SLAs.
