CUCM 11 - Conference Bridge not trusted

[Elysweyr]

Hello,

I was trying to set up Conference Now and due to the fact that it didn't work (call was accepted but no announcer) I've noticed this specific error message on the Media Ressources > Conference Bridge page.

1) What would be the most common way to start troubleshooting in order to get more helpful information on such a problem?

2) Errors an the conference bridge will affect the Conference Now feature as far as I know or should I keep troubleshooting in other areas in order to make Conference Now work?

Best regards,
Elysweyr

I had to allow the RTP streams originating from CUCM to reach the clients. That's all.
