Hi all,

I have deployed MRA single interface. In the internal corporate I am getting full audio features, perfect. While using MRA I cannot hear audio and ring back as well. I am using CUCM 11, 8.7.2 C&E.

All ports in firewall are open for test purpose and NAT reflection is correctly configured.

Certificates are uploaded correctly. 

Regards,

Shabeer

Is it single NIC deployment model with NAT enabled ? If yes, pls confirm below settings.

> Exp C is pointing to public IP address or FQDN of Exp E ?

> If pointing to the FQDN of Exp E for TLS, verify the FQDN must resolve to the Public IP
Address of Exp E (for this you need to have a A record in enterprise DNS for it).

If above settings are fine then it must be a network problem, if you can attach diagnostics logs of both C & E with tcp dump enabled then it can be confirmed.
