Short answer
It asks once more, and if it still cannot follow, it stops trying and hands the call to a person or takes a message. Guessing at what somebody said is worse than admitting it did not catch it, so the agent is built to fail toward a human.
Bad audio is the common cause, not accents. A caller on a highway with the window down, a job site with a compressor running, a phone held at the wrong angle. The agent handles more of this than people expect, and when it cannot, the fallback matters more than the recognition rate.
The rule is one clarification, then escalate. Systems that keep asking a third and fourth time are the ones people hang up on, and a hangup costs you the job that a clean handoff would have kept.
Every call is recorded and transcribed, so a call that went badly is a call you can listen to. That is the loop that makes the agent better: you hear where it lost the thread, we change the script, and the next caller in that situation gets a better call. Script updates are unlimited and included, because a system nobody is allowed to fix is a system that decays.
Settle it in ninety seconds
Call the demo line and talk to the agent yourself. It is the same system that would answer your phone, running live, and it will tell you it is AI if you ask it.
