For the issue you need to be more specific about the external connectivity into your cms whether its a VPN or through expressway , also u need to check cms logs by doing syslog follow , gather infos from your pc using Wireshark ,check expressway logs if u using it as a turn server for cms.

Finally check this ,it could help you :- https://community.cisco.com/t5/collaboration-applications/webrtc-error-unable-to-cponnect-media-rejoin-meeting/td-p/4176957

Hello ,

The problem is solved after putting  the ip address of DMZ 1 not of DMZ2 by cms    on  /api/v1/turnServers.
