- Deploy media gateways and Mediation Servers in a physically
secure environment.
- Install the Mediation Server on a computer with two network
adapter cards. The Deployment Wizard detects the presence of the
two network cards and writes their IP addresses to the
Communications Server listening IP addresslist and the
Gateway listening IP addresslist, both on the
Generaltab of the Mediation Server
Propertiesdialog box.
 Note: |

| Even if you configure the link between the Mediation Server and the media gateway for TLS, it is still good practice to further enhance security by configuring the Mediation Server with two network interface cards to separate its internal and external edges. It is possible to configure both edges on a single adapter card, but this alternative is not recommended. |
- Configure the internal edge of a Mediation Server to correspond
to a unique static route that is described by an IP address and a
port number. The default port is 5061.
- Configure the external edge of a Mediation Server as the
internal next hop proxy for the media gateway. The external edge
should be identified by a unique combination of IP address and port
number. The IP address should not be the same as that of the
internal edge; the default port is 5060.
