AI Voice Agent Compromised by Injected Looping Text

I am writing to report a critical issue with our AI calling agent.

Despite having a timeout set for 3 minutes, several of our calls have exceeded 180 minutes in duration. It appears that the receiver is playing an Arabic message followed by a beep for the entire duration of these calls. As a result, we have already been charged by Twilio for these extended durations.

Could you please investigate urgently what is happening and why the timeout is not being enforced in these instances?

Here are some of the room session ids:
