### Answer Yes, Retell AI supports multiple agents sharing one phone number through Agent Transfer (also known as Agent Swap) [(1) ]() . This feature allows you to transfer conversations from one AI agent to another without needing separate phone numbers for each agent . How it works: When using Agent Transfer, the destination agent doesn't need its own phone number — one number is all you need, no matter how many agents you transfer to . This is a significant advantage over traditional call transfer methods . Key benefits of Agent Transfer: - **Lower Latency**: The transition between agents is near-instant, much lower than transfer call - **Better Reliability**: No need to create a new phone call, avoiding potential telephony failures - **No Handoff Message Needed**: The destination agent has access to the full conversation history, eliminating the need for adding hand-off messages or repeated customer questions - **No Separate Numbers for Agents**: Agents receiving transfers don't need their own phone numbers To set up Agent Transfer: 1. Add an Agent Transfer Node from the 'Add New Node' menu 2. Configure the Transfer agent by selecting the ID and version of the specific agent to transfer to (you can select the latest version as well) 3. Configure optional settings like whether the agent should speak during execution and post-call analysis settings You can test agent transfer both in web call and playground .

### Answer I don't have specific information in the available sources about testing Agent Transfer in the web call or playground, or about "transfer failed" errors you're experiencing [(1) ]() . The LLM Playground documentation covers manual testing for basic conversations, function calling, and dynamic variables, but doesn't specifically mention Agent Transfer testing . If you're encountering "transfer failed" errors when testing Agent Transfer, I'd recommend: 1. Check that both the source and destination agents are properly configured 2. Verify the destination agent ID and version are correct in your transfer node settings 3. Review any error logs or call details for more specific failure reasons For more detailed troubleshooting on this specific issue, check out these potentially useful sources: [Manually test your agent]() I could try to provide a general answer based on my knowledge if you'd like, but I wanted to first clarify what's specifically documented.
