A platform for phone agents with a knowledge base, call translation and analysis.
Limit the task of a telephone agent
Retell AI is setting up a voice agent for calls. You can prepare a reference, set a script and pass the conversation to an employee. Connecting external actions requires its own customization. For a small team, a good first task looks simple: tell when the workshop opens, explain how to find an entrance, and pass the call to the person in case of a controversial issue.
The official documentation describes the API to create a call. Before connecting real telephony, it is useful to pass training calls with a test number.
Check the conversation with an unexpected clarification
Call a fictional workshop. First ask for hours of work, then interrupt the answer with a question about the address. Finally, ask for an action that is not in the certificate. In the analysis of the call, note whether the agent retained the meaning of the clarification and did not promise to perform an inaccessible operation.
Check the call transmission separately. Prepare a case when an employee is available and a case when there is no one to answer. This will show whether the subscriber has a clear continuation of the conversation in case of failure. Check if the reason for the transfer is preserved in the journal.
How to estimate the cost
The developer publishes the payment for use and start credits. The amount depends on the selected components and call parameters, so see the conditions for your number, voice model and route. The pilot is better to start with a small sample. On real calls, they determine in advance how to report the record, what data to transfer and to whom access to the journal is allowed.
