Judged on the call,
not on the demo.
Most of the work here went into the seconds a caller notices: the pause before the agent speaks, what happens when they talk over it, and what it does when it does not know.

The seconds that decide the call, how CallUltra handles live conversation
A voice agent is judged on the awkward moments, not the scripted ones. The agent connects to the model while the phone rings, publishes audio at the model’s native rate to skip a resample, and holds a steady fifty frames a second so the caller never hears it stutter.
- Warmed up while the phone is still ringing
- Stops when interrupted, ignores a passing "hmm"
- Hands over to a person without dropping the line
- Checks in on dead air rather than sitting silent
