TrueNorth Simphonē Pro Systems are flexible, scalable and apps-based. Installed with an Ethernet backbone, Simphonē systems have fewer components to be installed but offer a range of connectivity options, from high fidelity voice to high-speed Internet access. Simphonē Pro offers all that our Optelity products do, in a 4MCU form factor. Most systems are a direct swap—pull out the traditional Simphonē System and plug in the Simphonē Pro LRU, no additional wiring or configuration required.
