Use Cases

​

Customer Support Scaling

// Purchase numbers for different regions
const regions = [
  { area_code: "415", assistant_id: 101, name: "West Coast Support" },
  { area_code: "212", assistant_id: 102, name: "East Coast Support" },
  { area_code: "312", assistant_id: 103, name: "Central Support" }
];

for (const region of regions) {
  await purchaseNumber({
    area_code: region.area_code,
    provider: "telnyx",
    assistant_id: region.assistant_id,
    friendly_name: region.name
  });
}

​

Multi-Brand Management

// Different providers for different brands
await purchaseNumber({
  phone_number: "+18005551234",
  provider: "twilio",      // Premium brand uses Twilio
  assistant_id: 201,
  friendly_name: "Premium Brand Support"
});

await purchaseNumber({
  phone_number: "+18665554321", 
  provider: "telnyx",      // Budget brand uses Telnyx
  assistant_id: 202,
  friendly_name: "Budget Brand Support"
});

​

Geographic Expansion

// Search for numbers in new countries
const countries = ["GB", "AU", "DE", "CA"];

for (const country of countries) {
  const numbers = await searchNumbers({
    country_code: country,
    provider: "twilio",  // Use Twilio for international
    limit: 5
  });
  
  if (numbers.length > 0) {
    await purchaseNumber({
      phone_number: numbers[0].phone_number,
      provider: "twilio",
      assistant_id: getRegionalAssistant(country)
    });
  }
}

​

Cost Optimization Audit

// Monthly cleanup of unused numbers
async function monthlyAudit() {
  const numbers = await getOrganizationNumbers();
  
  for (const number of numbers) {
    const usage = await getNumberUsage(number.phone_number, 30); // Last 30 days
    
    if (usage.total_calls === 0 && usage.total_sms === 0) {
      console.log(`Releasing unused number: ${number.phone_number}`);
      await releaseNumber({ phone_number: number.phone_number });
    }
  }
}
