This step shows how to configure the E-SBC to use a TLS connection with the Lync Server
2013 Mediation Server. This step is mandatory for a secure SIP TLS connection.
4.8.1 Configuring the NTP Server Address
This step shows how to configure the NTP server's IP address. It's recommended to
implement an NTP server (Microsoft NTP server or third-party server) to ensure that the
E-SBC receives accurate and current date and time. This is necessary for validating
certificates of remote parties.
To configure the NTP server address:
1. Open the Application Settings page (Configuration tab > System > Application
Settings).
2. In the 'NTP Server IP Address' field, enter the IP address of the NTP server
(e.g., 10.15.21.10).
