Vapi AI

My voice agent is dropping calls every time it needs to transfer a call.  I setup a test agent and transferCall doesn't even trigger!

I'm supposed to have a demo for a client in a few days and my agent is essentially useless at this point. 

I see there's others experiencing this as well, any word on this please <@319034765808369666> <@865531204849500190> ?

Thanks

I'm really sorry to hear that you're experiencing issues with the transferCall functionality. It's crucial that your voice agent operates smoothly, especially with an upcoming client demo. I understand how important it is to resolve this quickly.

There might be several reasons why the transferCall isn't triggering as expected. It could be related to the configuration of your voice agent, network issues, or a problem with the API itself.

To assist you better, could you please provide me with more details about how you have set up the transferCall in your test agent? Any specific error messages you're receiving would also be helpful. Once I have more context, I'll do my best to guide you towards a solution.

You can continue this conversation by mentioning me in the message.

is number purchased from vapi? if yes then most likely your vapi number is marked as spam. 
so, instead use your twilio number or vonage and write email to support@vapi.ai describing the issue and with this discord support ticket title.
will do the refund for the number.

what if number is not purchased from vapi then use vonage.

sorry, what do you mean? the number we are using is purchased from twilio and connected to the agent.

Purchased from twilio directly right?  and call id please.

yes purchsed directly, where can i find the call id please

Got it: f8f2f031-a565-4e83-8b31-beace68a6f8e

Twilio Call Sid: CA9c29eaf80caba2411dc7d3e6ed7c9f5a

OK I will look into it thanks.

how about this call: c203ee8a-45d0-4dc3-b6a6-9b47080ca04e 

The tool doesn't not trigger at all.

For this sid check the status of number in twilio console it will show marked as `C` or `F` .

either use call_forwarding_number or add the tool call manually.

OK, i'm new to VAPI do i prompt call call_forwarding_number?
