Receiving this message when trying to call certain numbers. However, when these numbers are dialed from our landline phones the calls go through without issue. I am unable to find any correlation between the phone numbers that are having this issue. Could it be a specific wireless carrier or something?

are all your users having this issue with the same numbers they are trying to call?

Thank you, it looks like one of our main outbound numbers is being flagged as spam by one of the carriers.

one of my clients used free caller register to help avoid outbound calls being blocked.  this is also mentioned in the zoom support article.

federal communications commission (fcc) says "The FCC has made combatting unlawful robocalls and malicious caller ID spoofing a top consumer protection priority."

fcc has not been too effective.  some of the carriers use analytic services to prevent robocalls and spam.  these services sometime block legitimate calls.
