Hi, I'm having trouble with MCP and a voice call being triggered. The goal of this is to send a text at different intervals during the call, and I'm pretty sure I've got the Zapier MCP with Twilio set up correctly. The problem is it's not triggering effectively. The caller has to tell to voice assistant to text again after the voice assistant is supposed to do so. The MCP is correctly set up as a tool for the assistant so I'm assuming the error has something to do with my voice assistant prompt. Does anyone have any ideas?
