AudioCodes MEDIANT 1000B Voice Module M1KB-VM-2SPAN | T1/E1, DUA

Preserve critical voice connectivity while extending the life of your Mediant 1000B deployment. The AudioCodes M1KB-VM-2SPAN digital voice module adds two digital spans for T1/E1 environments, giving infrastructure teams a controlled path to integrate legacy telephony with modern unified communications. This module is designed for organizations that still depend on carrier circuits, PBX interconnects, or regional digital voice services. By adding dedicated span capacity inside the Mediant platform, it supports cleaner migration planning, tighter control over voice interfaces, and a more efficient use of existing gateway hardware. For enterprises where uptime, interoperability, and circuit continuity matter, a purpose-built voice interface card is often the right investment. It avoids the cost and disruption of replacing working telephony infrastructure while keeping the environment aligned with current communications requirements. The result is a more deliberate upgrade path, with hardware that fits the operational realities of large-scale voice networks.
