Here is my workflow link: https://dashboard.vapi.ai/workflows/7d4ca7af-796e-453a-9177-979a6dac6d32 As you can see in the last I have another Assistant in this. Now the problem is when it reaches the end and transfers to the second Assistant, it doesn't end the call automatically even after the communication seems completed. What could be the reason? https://cdn.discordapp.com/attachments/1368453306179125288/1368453306321600582/Screenshot_2025-05-04_at_10.31.39_AM.png?ex=681846f4&is=6816f574&hm=90d649dfb15bfa1635bf9f01be4e7a208065f3a256b1662da9570c252cd0cb43&

Based on the information available, there are several possible reasons why your call isn't ending automatically after transferring to the second Assistant. Is the

endCall

tool configured in your second Assistant's settings? According to Vapi documentation, the Assistant needs to have the

endCall

tool specifically enabled and properly configured to terminate calls automatically. To help diagnose your issue further, could you share how your second Assistant (the "Hospital at Home AI Agent") is configured, particularly regarding its tools and end call settings?

@Vapi Support Bot I have Enabled this in the second assistant, can you tell me anything wrong in this? https://cdn.discordapp.com/attachments/1368453306179125288/1368457190871928842/Screenshot_2025-05-04_at_10.48.33_AM.png?ex=68184a93&is=6816f913&hm=a79d98d29c1fa6a0bcea430bfa7052d80450f081b52193925909c4313457ffea&

I notice you've enabled the End Call Function, but there might be other factors affecting it. According to the information I found, the "Enable End Call Function" method is actually deprecated, and the newer recommended approach is to add the

endCall

tool type to your call configuration. Which language model are you using for your second Assistant? The documentation notes that the

endCall

function works best with GPT-4 and larger models, so this could be affecting its performance. Source: - [Vapi Documentation Default Tools](https://docs.vapi.ai/tools/default-tools)

GPT4.1 Nano @Vapi Support Bot

The issue is likely that GPT4.1 Nano isn't fully compatible with the

endCall

tool. According to documentation, the

endCall

function works best with GPT-4 and larger models. Instead of using the deprecated "Enable End Call Function", try adding the

endCall

tool type to your configuration:

json
"tools": [ { "type": "endCall" } ]

Also, set your model temperature to 0.3 for better performance. According to [Vapi Documentation](https://docs.vapi.ai/tools/default-tools), consider switching to a larger model like GPT-4 if the issue persists.

@Vapi Support Bot Ok thanks, can you also tell me the pricing of my AI assistant?

I couldn't find all the details about your AI assistant's pricing. You might want to check our [pricing page](https://vapi.ai/pricing). I'm escalating your query to a human agent for further assistance! 👍

total pricing is 5 cents per minute which is Vapi charge + Underlying provider cost.

Ok for buying number do we have to pay any additional charges?

Vapi provides up to 10 free US phone numbers per account with no extra charges if you’re not using Twilio.
