Day 1-2: Discovery & Configuration

1. Export your data from Vapi — call logs, contacts, and conversation flows
2. Configure CallSphere with your business knowledge base, hours, and workflows
3. Set up integrations — connect your CRM, scheduling tool, and payment processor
4. Define routing rules — how calls should be handled by type and urgency

Day 3-4: Testing & Refinement

1. Internal testing — your team calls the AI agent to verify responses
2. Edge case tuning — adjust for industry-specific scenarios
3. Integration verification — confirm data flows correctly to all connected systems
4. Escalation testing — verify human handoff works smoothly

Day 5: Number Porting & Go-Live

1. Port your phone numbers from Vapi to CallSphere (we handle the porting process)
2. Parallel running — both systems active briefly to ensure zero downtime
3. Cutover — Vapi deactivated, CallSphere handling 100% of traffic
4. Monitoring — CallSphere team monitors the first 48 hours post-migration

Is there a contract lock-in? No. CallSphere offers month-to-month billing with no long-term contracts required.

Can I run both platforms simultaneously? Yes. During migration, we recommend a brief parallel period where both systems are active. This ensures no calls are missed during the transition.

How long until I see ROI? Most businesses see positive ROI within the first month. The combination of flat pricing, 24/7 coverage, and zero missed calls typically pays for itself quickly.
