hi, i'm new to VAPI here. I just configured my assistant using their chat. How do i change the voice? Can i configure to hang up when getting voicemail? Can i upgrade the transcription to Deepgram?

everythign is configurable in the dashboard! if you click on assistants on the left hand nav you'll see the assistants you have created. Click on whichever one you want to work on and you can modify from there. you can also work fully from code if that's your preference - we have a skills library, mcp server and honestly sometimes i just point codex at the docs i want it to reference
