When planning the Avaya Session Border Controller for Enterprise (SBCE) for SIP Trunking, what is a good practice to adopt?

A. Name Interfaces consistently, for example, A1 for Internal network to Call Server and B1 for external to Trunk Server.

B. Name all internal and external interfaces exactly the same.
C. Use the same IP address on both, internal and external sides of the network.
D. Use one Avaya Session Border Controller for Enterprise on the internal and external sides of the network.

Use the same interface mapping throughout! Examples in this section use:
• A1 as the internal interface (to the call server)
• B1 as the external interface (to the trunk server)
