5. Infrastructure & Building Your Own Use Cases

When planning your infrastructure, consider the following key steps:

1. Assessment of Call Volume & Traffic:

   • Ensure compliance with local regulations for DID usage and international calling.

5. Scalability & Redundancy:

   • Plan for elastic scaling—most providers offer unlimited capacity on-demand.

   • Implement redundant network paths to ensure high uptime.

6. Monitoring & Analytics:
