Adds a phone number to your team's shared blacklist. Once added, calls from this number are blocked for all users in the team. An optional comment can explain the reason (e.g., "spam", "harassment"). If the number is already blacklisted, the request returns 304 Not Modified.

Permission: Numbers Write required.

Monitoring: Required. Team blacklist management is a supervisory feature. Returns 401 Unauthorized if Monitoring is OFF on your API key.
