Configure Logical Interface

The SBC Edge supports system-supported Logical Interfaces, which are used to hold the IP address for each Ethernet port. One of these logical interfaces is assigned an IP address for transporting the VoIP media packets (i.e., RTP, SRTP) and protocol packets (i.e, SIP, RTCP, TLS). In this example, Ethernet 1 is configured for transporting packets for the Microsoft Teams Direct Routing connection.

...

In the left navigation pane, go to Node Interfaces > Logical Interfaces.
