I use call.timeElapsed in single assistant configs to help prevent calls from lasting too long. Basically at 240 seconds first message says "We've been on this call for a while now so let's start wrapping this up" and at 300 seconds it says something like "I'm reaching the end of my time for this call. I'll pass this on to the team to follow up." Then triggers the endCall tool. Like I mentioned it works great for single assistants, but can get it to work in squad. Any else had any luck with this for squad?
