Advanced Use Cases
Streamlining Customer Service with Voice Call Workflows
A retail company looking to improve its customer service experience integrates programmable voice APIs to create streamlined voice call workflows for handling high call volumes efficiently. By leveraging voice APIs, the company builds an IVR system that automates call routing based on customer needs, enabling a seamless workflow that directs each caller to the right department or support agent.
When a customer calls in, the IVR prompts them to select from options like checking order status, returning an item, or speaking with a support representative. The voice call workflow uses data from the CRM to recognize repeat callers, automatically prioritizing VIP customers and connecting them to specialized agents. For cases where customers need to speak with live agents, the system can analyze call patterns in real-time and adjust the workflow, such as sending high-priority calls directly to available agents, while routing general inquiries to an automated queue with callback options.
With this programmable voice API solution, the company enhances the customer experience by reducing wait times and improving call resolution. At the same time, the workflow reduces the workload on agents, allowing them to focus on complex cases while routine inquiries are managed efficiently through automation.
