Components in Detail

Multi-Department Routing

Intelligent Routing System

interface RoutingDecision {
  department: 'sales' | 'support' | 'billing' | 'onboarding'
  voiceAgentId: string
  priority: 'normal' | 'high' | 'critical'
  reason: string
}

async function routeCall(callContext: CallContext): Promise<RoutingDecision> {
  // 1. Load customer profile
  const customer = await crm.getCustomer(callContext.phoneNumber)

  // 2. Determine intent via LLM (from greeting dialog)
  const intent = await classifyIntent(callContext.initialUtterance)

  // 3. Apply routing rules
  if (customer?.tier === 'enterprise') {
    return { department: intent.department, priority: 'high', ... }
  }

  if (customer?.hasOpenTicket) {
    return { department: 'support', priority: 'high', ... }
  }

  return { department: intent.department, priority: 'normal', ... }
}

Routing Matrix

Fallback Strategies

Multi-Level Fallback System

Level 1: Voice agent tries to resolve the concern
    ↓ (fails after 2 attempts)
Level 2: Different voice agent with extended prompt
    ↓ (fails after 1 attempt)
Level 3: Handoff to human agent with full context
    ↓ (no agent available)
Level 4: Callback agreement + create ticket

Fallback Triggers

Analytics Dashboard

Real-Time Metrics

Business Intelligence

-- Top 10 reasons for escalation to humans
SELECT
  escalation_reason,
  COUNT(*) as count,
  AVG(customer_satisfaction) as avg_csat
FROM call_analytics
WHERE transferred_to_human = true
  AND date >= CURRENT_DATE - INTERVAL '30 days'
GROUP BY escalation_reason
ORDER BY count DESC
LIMIT 10

Reporting

• Daily report: Automatically emailed to team leads
• Weekly review: Analyze failed conversations
• Monthly business review: ROI, trends, optimization potential
• Real-time alerts: On sudden CSAT drop or error spike

Compliance Recording

GDPR-Compliant Recording System

interface ComplianceRecording {
  callId: string
  timestamp: Date
  participants: string[]
  consentGiven: boolean
  department: string
  audioUrl: string // encrypted S3 link
  retentionDays: number
  autoDeleteDate: Date
}

async function startComplianceRecording(call: Call) {
  // 1. Play consent announcement
  await call.playAudio('consent-announcement.mp3')

  // 2. Wait for confirmation
  const consent = await call.waitForResponse(10_000) // 10 sec timeout

  if (!consent.approved) {
    await call.playAudio('no-recording-notice.mp3')
    return { recording: false }
  }

  // 3. Start recording
  const recording = await call.startRecording({
    encryption: 'AES-256',
    storage: 's3://compliance-recordings/',
    retention: 90, // days
  })

  return { recording: true, recordingId: recording.id }
}

Retention Periods

Privacy Checklist

• Consent announcement before recording
• Opt-out option for the customer
• Encryption at-rest and in-transit
• Access logging (audit log)
• Automatic deletion after retention period
• Anonymization option for analytics
• Right of access: Customers can request their recordings
• Data Protection Impact Assessment (DPIA) documented

Practical tip: An enterprise voice agent platform is a marathon, not a sprint. Start with one department (e.g., support), prove the ROI, and expand gradually. The architecture should be multi-tenant capable from the start — even if you initially have only one tenant.
