Is there any way to initiate a live transfer to an external phone number? __We would like the following behavior:__ 1. Transfer is initiated to a phone number located in our VOIP provider directed to a live agent after qualification. 2. The assistant and customer are connected to the live agent. 3. The assistant gives an introduction to the live agent then leaves the call. __In Summery:__ we are looking for a 3 way conference with an introduction, rather than just redirecting the call to an outside number while having the customer on hold. This would allow us to have the most seamless transfer and ensure that hangups do not occur nearly as often.

Hi ABC1235, To assist with transfer-related issues, you can utilize the

transferCompleteAudioUrl

property in the

TransferPlan

when using

warm-transfer-experimental

mode to play a notification sound after a transfer is complete, as detailed in the [May 25, 2025 changelog](https://docs.vapi.ai/changelog/2025/5/25). If you encounter any additional questions or require further setup instructions, feel free to reach out.
