AudioCodes Mediant 2600 Session Border Controller – 12-Port High-Capacity SBC, AC-Powered for Enterprise SIP Trunking (M26-12/B/R/AC)

The AudioCodes Mediant 2600 (M26-12/B/R/AC) is a 12-port, high-capacity enterprise Session Border Controller in a 1U form factor with AC power and hardware redundancy support. Designed for large enterprise headquarters, data center SBC deployments, and service provider edge applications, it delivers advanced SIP security, media processing, and interoperability across a wider range of network interfaces than the 2-port variant. It supports Microsoft Teams Direct Routing, Zoom, and major UCaaS and on-premises UC platforms.

The Telecom Spot Take

The M26-12/B/R/AC is the high-density Mediant 2600 configuration for environments that need maximum interface flexibility and redundancy built in. Twelve ports let you connect to multiple SIP carriers simultaneously, maintain active and standby network interfaces, and handle multi-tenant or multi-network segmentation without running out of physical connectivity. The "R" in the SKU indicates redundancy options — critical for production SBC deployments where gateway downtime translates directly to lost calls. For enterprise IT architects designing a resilient, carrier-grade SBC that will anchor a large Teams or Unified Communications environment, this is the Mediant 2600 variant to specify.

Key Features
