  1. What is the primary purpose of the AudioCodes High Availability (HA) configuration?

    Answer: To ensure continuous service by providing automatic failover to a standby unit

    AudioCodes HA provides continuous service availability by automatically switching traffic to a standby unit when the active unit fails.

  2. In an AudioCodes 1+1 HA pair, what is the role of the 'Standby' unit?

    Answer: It remains synchronized with the active unit and takes over immediately upon failure

    The standby unit continuously mirrors the active unit's state so it can assume the active role instantly when a failure is detected.

  3. Which dedicated connection is required between two AudioCodes units forming an HA pair?

    Answer: A dedicated HA synchronization link (Ethernet cable or port)

    A dedicated HA link (a direct Ethernet connection between the two units) is required for state and configuration synchronization.

  4. What is the 'Virtual IP Address' used for in an AudioCodes HA deployment?

    Answer: It serves as the single shared address used by SIP peers and trunks, floating between active and standby

    The virtual (shared) IP floats between the active and standby units, so SIP peers never need to reconfigure their targets during a failover.

  5. What automatically triggers an HA failover in an AudioCodes system?

    Answer: Detection of a critical failure on the active unit, such as hardware fault or process crash

    Automatic failover is triggered by detection of a critical failure (hardware, software process crash, or network link failure) on the active unit.

  6. Which AudioCodes product series is commonly deployed in 1+1 HA configurations for enterprise and carrier environments?

    Answer: AudioCodes Mediant series (e.g., Mediant 2000, 3000, 9000)

    The Mediant series gateways and SBCs support 1+1 HA, making them suitable for carrier-grade and large enterprise deployments.

  7. During an AudioCodes HA switchover, how is configuration consistency between the active and standby maintained?

    Answer: Configuration is continuously synchronized from the active unit to the standby unit over the HA link

    AudioCodes HA continuously replicates the active unit's configuration and call state to the standby unit via the HA link, ensuring immediate readiness.
