Regularly reviewing the effectiveness of the tools in a business's tech stack is essential, especially for companies that are scaling up. Initially, all-in-one solutions like Communications Platform as a Service (CPaaS) offer a cost-effective way to quickly develop and deploy communication services. However, as businesses grow and expand into new markets, the limitations of CPaaS become apparent, particularly in terms of rising costs and reduced quality due to aggregated voice coverage from multiple providers. To address these challenges, businesses can either build their own voice network, which is costly and time-consuming, or adopt a strategy known as Bring Your Own Carrier (BYOC). BYOC allows businesses to integrate their preferred telephony providers with their CPaaS platform, enhancing service quality, reducing costs, and ensuring better support and accountability. This approach allows businesses to retain the benefits of CPaaS's platform features while optimizing their telephony infrastructure, ultimately improving customer experience and achieving greater return on investment.
