I am stuck in an issue. I want to interrupt the VAPI AI Voice Agent in between for our IVR Assistant. Currently after the bot finishes to speak, after than if we press 1,2, or 3, then it works, but if we type 1 in between it does not interrupt the assistant. I tried every confugration possible and also asked VAPI's AI assistant on the website, still it does not interrupt/barge-in. Can anyone please help.
