TelcoBridges and Trunking
TelcoBridges Tmedia and Tdev devices provide trunking capabilities. Multiple different network connections from multiple different service providers (backhaul carriers, international carriers) can terminate in a Tmedia or Tdev device. Call routing can then be applied over top to achieve customer service and operational savings objectives.
