Extensive SIP interoperability

Mediant 3000

NEBs compliant, fully redundant TDM gateway (OC-3/STM-1 or DS3) with SBC capabilities for medium-to-large sized enterprises.

  • For medium to large-sized enterprises
  • High-availability hybrid gateway with SBC capabilities
  • Comprehensive SIP interoperability
  • Supports OC-3/STM-1 optical link or DS3 electrical links


The AudioCodes Mediant 3000 media gateway and enterprise session border controller (E-SBC) provides a complete voice connectivity solution for medium-to-large sized enterprises.

Supporting up to 2,016 channels in a 2U NEBS-compliant platform, the Mediant 3000 offers OC-3/STM-1 optical link and DS3 electrical links connectivity between TDM and VoIP networks. The Mediant 3000’s carrier-grade design delivers high availability through its 1+1 redundant architecture.

The platform connects any SIP to SIP environments and IP-PBXs to any SIP trunking service provider, scaling to 1008 concurrent VoIP sessions per shelf. It connects the TDM to the packet-switched network, preserving investment in legacy telephone and PBX systems.
