Product specifications subject to change without notice.

NEC’s IP-based products utilize Voice over IP (VoIP) technology to deliver remote voice solutions. The voice quality of these solutions is dependent on variables such as available bandwidth, network latency and Quality of Service (QoS) initiatives, all of which are controlled by the network and Internet service providers. Because these variables are not in NEC’s control, it cannot guarantee the performance of the user’s IP-based remote voice solution.

Certain features may be optional, not applicable to all systems or require additional equipment. The information contained herein is subject to change without notice at the sole discretion of NEC America.
