Mediant 1000 Hybrid Media Gateway

The AudioCodes M1KB-ESBC is a hybrid media gateway designed for enterprises and service providers migrating voice networks. It combines session border controller functions with media gateway capabilities in a single appliance. The unit supports both analog and digital TDM interfaces for legacy connectivity. It targets IT teams needing secure SIP trunking and PSTN integration.

Sustained SIP normalisation and routing

Rich SIP normalisation and routing mechanisms maintain seamless interoperability during continuous traffic loads. The hybrid SBC architecture handles ongoing signalling and media translation without relying on burst-only capacity. Advanced monitoring tools provide constant visibility into call quality and service metrics. Enhanced perimeter defence mitigates DoS attacks across extended operating periods.

Replaces separate SBC and gateway boxes

This appliance consolidates a standalone session border controller and a traditional media gateway into one platform. The migration path suits organisations moving from pure TDM infrastructure to SIP-based telephony. PSTN fallback remains available for resilience during the transition. Buyers who require only analog extension ports or pure cloud UC without on-premises PSTN breakout should consider simpler alternatives.

Questions about this item

How much power does the Mediant 1000 Hybrid Media Gateway draw during continuous operation?

The supplier data does not publish a continuous power-draw figure for the Mediant 1000 Hybrid Media Gateway.

Which analog or digital TDM interfaces must already be present on site for the M1KB-ESBC to connect?

The gateway supports both analog and digital TDM interfaces, so existing FXS, FXO, E1 or T1 ports can be used directly.

Will the M1KB-ESBC interoperate with an older SIP trunk that uses non-standard headers?

Its SIP Normalization and Routing Mechanism rewrites headers and parameters so legacy trunks work without changes.
