Call recordings are stored on an external Windows or Linux based recording server, on
which the agent provided by New Rock collects and stores the call recording files.
For more information, see the Recording Agent User Guide in
http://www.newrocktech.com/ViewProduct_E.asp?id=64.
Set this parameter to the IP address of the server.
Note: The recording function needs to be enabled for the subscriber line.
Gateways support several mechanisms for NAT traversal. Usually, static NAT is used
when a fixed public IP address is available. It’s necessary to perform port mapping or
DMZ function on router when choosing dynamic or static NAT.
