Hey everyone! I've set up a Vapi AI caller using GHL and Make.com. I've bought and imported the phone number from Twilio. Unfortunately, every single call the AI made (but one) went straight to voicemail. Initially Vapi support told me to enable SHAKEN/STIR on Twilio - but after doing that, and having the STIR grade now as A, the calls are still going to voicemail. Have you ever experienced this? And how did you resolve it?
