Protect enterprise voice traffic with a redundant AudioCodes M800 configuration built for session border control and SBC/SBA deployments. This package is designed to keep calling services available when network paths, trunks, or primary systems are interrupted, helping IT teams preserve inbound and outbound communications without forcing a full service outage. By combining redundancy with PSTN support, the M800 gives infrastructure teams a practical fallback path for critical voice traffic. That matters in environments where contact centers, executive communications, branch telephony, or operational hotlines cannot wait for a maintenance window. The result is a deployment that supports continuity, routing resilience, and more predictable recovery behavior. For teams standardizing on AudioCodes voice infrastructure, this package fits into enterprise telephony architectures that require controlled failover and dependable call handling. It is a strong fit when the cost of downtime exceeds the cost of building in a second path. Rather than adding complexity later, this model is selected up front for environments where availability, routing control, and PSTN reach are part of the design brief.
