Hi,

For no Media When You Call Through MRA the following can be an issue:

In a single NIC deployment with NAT configured, these parameters are either missing or not configured correctly:

• Expressway-C is not pointed to the Public IP address of Expressway-E, which allows the firewall to hairpin the signaling.
  
  
• If pointing to the FQDN of Expressway-E for TLS, verify the FQDN must resolve to the Public IP Address of Expressway-E.
  
  
• These are not configured on Expressway-E:
  
  

  xConfiguration Ethernet 1 IP V4 Address: "<Internal_IP>"
  xConfiguration Ethernet 1 IP V4 StaticNAT Address: "<Public_IP>"
  xConfiguration Ethernet 1 IP V4 StaticNAT Mode: "On"
