Hey, I have an agent using mostly for outbound calls with some input values like {{prospectEmail}} but when I get an inbound call I don't have this value, but I made a tool to find the email based on the phonenumber if user call us back. But I can not make the agent to call my tool. I tried to promt it to call every time when it's an inbound call (I'm assuming agent don't know if it's and inbound or outbound call, and I didn't see any variable that contains that info), but nothing. I tried to ask if my variable is empty but nothing. Only doeas when I ask it what is my email address then using the tool. What is the best solution for this?
