The disclosed invention provide system and method to ensure resiliency in a network where audio capturing service experiences a failure on one or more active nodes. The network failover system is coupled to a Layer 3 (L3) network and communicates with a network switch through which network packets are transmitted. The failover system performs operations that include receiving network packets that are mirrored via the network switch, monitoring a primary node that captures audio data in the network packets, sending the network packets to a fallback node during an outage of the primary node, examining the network packets to determine which packets are audio-related packets, collecting audio-related packets, and storing the collected audio-related packets in a data storage. The fallback node is in the Layer 3 (L3) network.
