Absolutely, I'd be glad to assist you with this issue. It sounds like you've reached the concurrency limit for outbound calls, which is why you're experiencing difficulties making further calls and seeing 'unknown' statuses in your call logs.
To resolve this, we can look into increasing your concurrency limit. This will allow you to make more outbound calls simultaneously. However, I'll need some additional information to proceed with this request. Could you please provide me with your account details or the specific parameters you'd like to set for the new concurrency limit?
Once I have the necessary information, we can take the appropriate steps to adjust your concurrency limit and get your outbound calls running smoothly again.
