Question: I need a solution that can automate customer service calls and route them to human agents when necessary.

For automating customer service calls, Verloop has a full-featured option with its conversational AI platform. Verloop.io automates both chat and voice interactions to increase agent productivity and customer satisfaction. It offers automated support, live chat, and an NLP-powered FAQ, and is well-suited for e-commerce, banking and travel companies.

Another strong contender is Elto, a more advanced live conversation AI for phone calls. Elto can talk for up to an hour and take follow-up actions, with features like Human Handoff, Knowledge Bases and Custom Voices. It's designed to be a scalable, low-latency option that fits with existing technology, and is a good choice for businesses that need to handle a lot of calls.

Zendesk is another strong option, an all-in-one customer service software package. Zendesk uses AI to personalize interactions across many different communication channels, including phone calls. Its AI Agents can work alongside human agents to handle customer service requests, and the company says it optimizes team performance and interaction quality. That makes it a good choice for businesses of all sizes that need to scale and customize their operations.

PolyAI is another powerful option, using more advanced voice AI technology to handle complex questions and provide a consistent brand voice. It can handle calls in multiple languages and reduce wait times for customers. That should improve satisfaction and make operations more efficient. The company's technology fits with existing technology stacks and offers analytics to help fine-tune customer service interactions.
