Delivers low-cost and flexible media processing

Our vMRF is equivalent to our carrier-grade MPX-12000, but runs on common, industry-standard server hardware. It is available in ‘bare metal’ form or as a virtual appliance, running on leading enterprise Linux distributions and virtualization platforms. The vMRF is aimed at customers looking for media processing with lower port densities, in lab environments or as a stepping-stone to cloud deployments.
