Our assistant does a lot of call transfers and we need to detect if the transferred call goes to voicemail. The voicemail detection was configured as explained in [the documentation](https://docs.vapi.ai/documentation/advanced-concepts/calls/voice-mail-detection) but it is not happening. As soon as call transfer happened, we get "end-of-call-report" with

endReason

being

assistant-forwarded-call

. Instead we need the assistant to detect if the forwarded call goes to VM and if so then send is an

end-of-call-report

with

endReason

being

voicemail

. Do we call forwarding through special "Transfer Call" function as explaind [here](https://docs.vapi.ai/documentation/advanced-concepts/calls/dynamic-call-transfers) Can we make this happen with VAPI? Thank you!!

Hey you can checkout this documentation

We have already checked the documentation many times over. The problem is not even in the voicemail detection. The problem is because the VAPI assistant sends

end-of-call-summary

notification before it even had a chance to detect the voicemail. It sends the notification as soon as it forwarded the call, without even waiting for the new phone to answer. In other words, how can we make for forwarded calls to detect voicemail? I already tried to set

transferPlan.mode

to

warm-transfer-wait-for-operator-to-speak-first-and-then-say-message

but this didn't help. Will you help? Thanks

Ah, I see. Apologies for the misunderstanding - I initially thought you were asking about detecting a voicemail call at the start. However, I don't believe it's possible to detect a transferred call's voicemail.

Is there is a way to submit a new featuree request? Also, [your documentation](https://docs.vapi.ai/api-reference/tools/create#request.body.transferCall.destinations.number.transferPlan) says that the forwarded calls support

transferPlan

. I tried this feature to announce the call summary to the number the call is forwarded to but this does not seem to work. Here's my settings for the

transferPlan

. I attached a photo of what i setup in

transferPlan

. Am I doing something wrong? Thanks https://cdn.discordapp.com/attachments/1338967884025823364/1339646004072284210/image.png?ex=67af7a10&is=67ae2890&hm=3c73149d19d7614ac6e108e6d229327a85ecdeed5eea6ea2add61e5bcb21c060&
