NEC DSX VoIP (Voice Over IP) - Version 3 Firmware

Install DSX IP keysets on-premise in a managed network or off-site in a remote office. Choose between two types of DSX IP extensions: the 34-Button Backlit Display and the 34-Button Backlit Super Display. These feature-rich IP keysets offer the same features as their digital counterparts, have Full Duplex speakerphones, and are quick to set up in an IP environment. Each DSX IP Keyset uses a single, low-profile Ethernet cable to the desktop connected to a compact, unobtrusive DSX IP Phone Adaptor. Compliant third-party SIP phones, soft phones, and ATAs are also supported.

Requires NEC DSX Firmware version 3 which can be downloaded and installed for free.

We recommend that you have a full understanding of networking and the real-time requirements of voice transmission over data networks (QoS, MOS, VLANs, compression, and bandwidth to name a few) before purchasing any VoIP equipment from any VoIP reseller. Remember that it is the salesman's job to make the sale, not make you happy. We want happy, repeat customers - so, if you have questions, please contact us with questions prior to your purchase.
