Contact centers have been under pressure to maintain operational efficiency and cost-effectiveness during the lockdown, prompting a focus on several strategies to reduce communication expenses. Transitioning to cloud-based communication services is suggested as a significant cost-saving measure, potentially reducing IT spending by replacing traditional capital expenditures with manageable subscription models. Consolidating communication suppliers can streamline operations and yield volume-based discounts, further decreasing costs. The 'Bring Your Own Carrier' (BYOC) approach is recommended for maintaining control over call routing and extending market coverage by allowing businesses to choose their network suppliers independently. Automating processes through APIs can save valuable time and resources by handling tasks like regulatory submissions and number porting, although inconsistencies in API use across countries can pose challenges. Finally, maintaining high call quality is emphasized as a crucial factor in differentiating customer experience, with troubleshooting tools necessary to ensure seamless support and interaction.
