The MIU is capable of either standalone operation or part of a peer-to-peer distributed network of other Mercury devices supporting a virtually unlimited number of users.


  • Up to 32 physical ports for hardware panels, telephony (FXO, FXS), radiointeroperability, Cross Domain Solutions (CDS) and analog audio communications
  • Up to 64 simultaneous IP audio channels
  • Supports low-latency, HD audio and signaling with other Mercury peers
  • Hosts up to 64 Trilogy Virtual Panels (iOS, Android or Windows)
  • Facilitates interfacing with up to 64 SIP-enabled endpoints supporting both point-to-point and PBX based connectivity.
  • Enables RoIP (Radio-over-IP) over any IP network
  • Compatible with conventional telephony equipment (POTS)
  • Ideal for extending all types of voice communications over IP networks
  • Capable of multicasting encoded audio over IP network using a variety of supported codecs
