Oracle Communications Session Border Controller Implementation

Which two of the following statements are true regarding dynamic realm bridging?

Choose two
  • A Egress realm can be any, depending on time-of-day, called number, and so on.
  • B Dynamic realm bridging is the routing of a signaling message coming from a given ingress realm to a next hop in an egress realm.
  • C Dynamic realm bridging is a one-to-one association accomplished by using SIP-NAT.
  • D Ingress and egress realms are unconditionally paired.
  • E Dynamic realm bridging decisions are based solely on layer 3 (IP) information.
Explanation

Dynamic realm bridging routes signaling from an ingress realm to a next hop in a selected egress realm. Local policies can select that routing based on source and destination addressing, including called numbers, and can be controlled by activation and time-of-day settings. Therefore, the egress realm can vary according to policy rather than being permanently paired with the ingress realm or determined solely by Layer 3 information. SIP-NAT bridging is a separate method and supports both many-to-one and one-to-one configurations.
