I’ve run into something similar before with transfers dropping right after the trigger, and in most cases it came down to how the transfer number was being updated or how VAPI was handling the target endpoint. Since you’re pushing the update through Make, it’s worth double-checking if the patched number is actually being registered as a valid forwarding destination. Also, routing through OpenPhone can sometimes cause issues if the free VAPI numbers aren’t fully provisioned for external transfers. @FrostbyteLegacy
