Keep enterprise voice infrastructure aligned with modernization goals using the AudioCodes Mediant 1000B configured with 2 spans and 2 AC. This gateway is intended for organizations that need to preserve telephony continuity while transitioning from legacy TDM services to SIP-based communications. The 2-span design makes it a practical fit for smaller interconnect requirements, remote sites, or targeted migration projects where a full-scale gateway would be unnecessary. Dual AC support adds operational resilience, helping maintain service availability in environments where voice traffic remains business-critical. For infrastructure teams, the value is in control. Instead of replacing working telephony assets all at once, this gateway supports a staged approach that reduces disruption and protects existing investments. It is a strong fit when reliability, migration discipline, and deployment efficiency matter more than feature excess. In that context, the Mediant 1000B delivers the right balance of capacity and continuity for enterprise voice planning.
