Why CallSphere for uptime and reliability
CallSphere runs 6 production AI voice and chat agent platforms today, serving businesses in all 50 US states. Each agent has access to 14 function tools (appointment booking, payment capture, CRM upsert, calendar sync, knowledge-base retrieval, SMS handoff, and more), speaks 57+ languages, and answers in under 1.5 seconds end-to-end. Pricing starts at $19/mo, chosen by what you need the AI to do rather than call volume, up to Custom Build at $149/mo for custom applications and ongoing development. Onboarding takes 24 hours for most teams, and you can explore a live demo before choosing a plan.
Uptime and reliability questions, answered
The questions buyers ask most often before they sign.
What's CallSphere's uptime SLA?
The platform targets 99.9% uptime, measured monthly, across every plan. Enterprise customers receive a contractual 99.95% SLA in a dedicated document with service credits for breaches.
What happens to calls during an outage?
Voice calls forward to your configured fallback number (a backup queue, on-call mobile, or partner answering service). Chat surfaces a maintenance banner with the incident URL and an estimated recovery time. No calls are dropped silently.
How is uptime measured?
Synthetic agents place a test voice call and a test chat session every 60 seconds across all 6 production verticals. A region is considered down if 3 consecutive checks fail. Public status reflects the last 90 days rolling.
How will I be notified of incidents?
Email to your account admins, webhook to your /incidents endpoint if configured, and a banner on the customer dashboard. Enterprise customers receive a phone call from on-call within 15 minutes of P0 incidents.
