Could you describe your infrastructure setup?
Where is the CMS placed? Where is the FW? Do you NAT from a public IP to CMS private IP? etc ...

Just by your short description, the problem could be anything.

The Cisco setup for CMS with public access is like this:
1 CMS (Core) in the internal network and 1 CMS (Edge) in the DMZ, providing TURN relay (behind the NAT-FW).

before I explain my design I want to say thank you for your respond. I designed single CMS and set IP private to all it's component and after that connected CMS to ASAv for publishing and I open https and http on ASAv.that's all my design.

@b.winter by the way i deploy webbridge3 callbridge dns ntp that's all component deployed on cms

I guess you have a problem with the media connection over the NAT. Because you have no TURN-server in your deployment, which provides this media relay via NAT.

That's why you have Expressway or CMS-Edge as TURN-server in the DMZ.
