I have tested the transferCall function for the same voice assistant but with 2 different numbers: one being a french mobile phone number (starting with 06), the other one a landline number (starting with 04). With the mobile phone number during the call the message saying the transfer has started is triggered, but the calls ends abruptly just after. With the landline the transfer is done well. Here are the call id: - Mobile: 80edc3dc-7ce2-44d6-8297-e6c46b11c1de -Landline: 11fd0b64-8be7-4e49-887a-86509e92c109

its old issue

Looking into it
