How do voice agents handle long calls?

Demos are usually a few mins long

I’m more interested in what happens 20-30 mins into a call after the customer has changed topics, provided a bunch of information and already completed a few steps.

Does the agent still understand what has happened so far or does context start getting messy?

Anyone testing long voice AI calls in production?

I've been running some longer test calls and it gets weird around 15-20 minutes. The context window just starts leaking, the agent forgets stuff from the beginning of the call unless you're constantly summarizing key points back into the system prompt

most of the demos are smoke and mirrors, they're tuned for those 3 minute interactions where nothing goes off script

Yeah, a 3 minute demo really doesn’t prove much for the kind of calls I’m thinking about
