Manual status control for unanswered API calls

Business problem

When using a custom voice channel integrated via Twilio and the API, calls that are not answered are automatically assigned a 'closed' status in Trengo. This prevents the team from accurately tracking and following up on missed calls, as they disappear from the active workload without manual intervention.

Wished result

The ability to prevent tickets from being automatically closed when a call is unanswered, ensuring missed calls remain visible in the inbox for better oversight and manual follow-up.
