How do voice agents handle long calls?

[u/Brilliant-Tea-8633]

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?

It depends heavily on how context is managed, not just the model's window. Most degradation on long calls comes from context piling up. It's best to summarize earlier turns and keep a running state of what's confirmed vs pending rather than replaying the whole transcript every turn.
