New and unused.  The FortiVoice Gateway works in conjunction with your FortiVoice phone system to expand the resources and connect different line types to the system. The gateways are supported on the FortiVoice Enterprise systems, FVE-100E and larger.  The FortiVoice Gateway solution provides ease of support for additional phone lines or analog extensions. The compact design and simple configuration makes growing your network a snap, and with the stackable design you can add as many gateways as you need now or later on as you grow.
