7.3.2 Configuring Network Interfaces
This section describes configuring the IP network interfaces for each of the following interfaces:
◼ LAN Interface (assigned the name "LAN_IF")
◼ WAN Interface (assigned the name "WAN_IF")
To configure the IP network interfaces:
1. Open the IP Interfaces table (Setup menu > IP Network tab > Core Entities folder > IP
Interfaces).
2. Configure the IP interfaces as follows (your network parameters might be different):

7.4 Configuring TLS Context for Zoom
This section describes configuring the SBC for using a TLS connection with the Zoom Phone Cloud
System. This configuration is essential for a secure SIP TLS connection.
The procedure involves the following main steps:
◼ Configure the NTP Server Address
◼ Creating a TLS Context for a Zoom Phone System
◼ Generating a CSR and Obtaining the Certificate from a Supported CA
◼ Deploying SBC Signed and Trusted by Zoom Root Certificates
7.4.1 Configuring NTP Server Address
This section describes configuring the NTP server's IP address. It is recommended to implement an
NTP server (local NTP server or another global NTP server) to ensure that the SBC receives the
current date and time. This is necessary for validating certificates of remote parties. It is important,
that the NTP Server is located on the OAMP IP Interface (LAN_IF in our case) or be accessible through
it.
To configure the NTP server address:
1. Open the Time & Date page (Setup menu > Administration tab > Time & Date).
2. In the 'Primary NTP Server Address' field, enter the IP address of the NTP server
(e.g., 10.15.27.1).
3. Click Apply.
