Remote Site Survivability

Release E-C[xz]6.4.0 M2 includes a new feature called Remote Site Survivability. This feature is the Oracle® Enterprise Session Border Controller’s ability of a Remote Office/Branch Office (ROBO) to detect the loss of communication over SIP-based telephony, to the Enterprise’s core call processing Data Center. When loss of communication is detected over the SIP service, the ROBO Oracle® Enterprise Session Border Controller dynamically switches into Survivable Mode, locally handling call processing and providing limited additional server functionality.

Note:

Remote Site Survivability supports SIP only. It does not support the H.323.

The following are features of Remote Site Survivability:

• Works with or without High Availability (HA) operation.
• Configurable in real-time - no reboot required to enable this feature.
• Allows configuration of the feature via the Oracle® Enterprise Session Border Controller Web GUI
• Maintains Historical Recording (HDR) statistics about being in survivability mode, such as:

  Whether or not the Oracle® Enterprise Session Border Controller is in survivable mode using the ACLI command, show health.

  Length of time the Oracle® Enterprise Session Border Controller was in survivable mode (records number of times and amount of time in survivability mode)

  Number of SIP messages handled in survivable mode

  Number of SIP users registered locally in survivable mode (both existing based on cache, and separately - new registrations).
