Hello!
I'm sorry to hear that you're experiencing disruptions in your conversation flow. This "hang" could be due to a variety of reasons such as network latency, issues with the VAPI service, or even problems with the device you're using.
To help you better, could you provide me with more details about when the hang occurs? For example, is it happening during specific functions or at random times? Any additional information you can provide will be very helpful in diagnosing the issue.
