I am building an ai assistant to navigate automated phone trees (IVR) of banks to automate a manual task for my real estate business. However, the ai assistant responds way too often (despite high interruption thresholds) and breaks the phone tree. Honestly, because of the pauses built into customer service lines, we actually need the ai to NOT respond most of the time. Has anybody been able to prompt their vapi assistant to not respond or use dtmf tones unless absolutely necessary to achieve its goal? Cc @User if you have any tips?
