DSX VoiP Keysets and Phones for anywhere! Install them in your office, remote office or home!

With the DSX Phone System you can install DSX IP keysets (voip phones) both on site on your managed network or off site in a remote office. NEC offeres two types of DSX IP extensions: the 34-Button Backlit Display and the 34-Button Backlit Super Display.

Each DSX IP Keyset uses a single Ethernet cable to the desktop connected to a compact DSX IP Phone Adaptor. Compliant third-party SIP phones, soft phones, and ATAs are also supported.

New in DSX v3.2 DSX System Software Version 3.2 is an important new release that features three major VoIP enhancements:
• Peer-to-Peer communication between IP extensions
• NAT Traversal with Any Router
• Improved ATA and SIP SLT Support

New in DSX v3.2 With Peer-to-Peer, DSX IP keysets and other SIP devices in the same office do not use VoIP Gateway ports when talking to each other. VoIP licenses are only required for calls to TDM resources and off-premise IP phones.

New in DSX v3.2 NAT Traversal with Any Router for DSX IP keysets means you no longer have to limit your remote offices to the LinkSys routers previously recommended.

Hot Features your will actually use every day!

Hot Dial Pad! A popular feature. The hot dial pad can be enabled. This allows you to dial without having to select a phone line first or even lifting up the handset! You just start dialing and your call will automatically be routed to the prime line outside line settings!

New in DSX 3.2 Hot Dial Pad!

User Level Programming - This allows the user to set features on thier own telephone with contextual soft key and display driven menus. With DSX 3.2, this has been greatly enhanced and will use all three lines on the DSX phone display to provide better guidance when selecting options and setting your preferences.

DXS Has Simplfied but powerful call handing and routing:

The newly added Line Scheduling to set up how you want to receive your incoming calls. You will be amazed at all the different call scenarios this can handle. With the Skip Ahead feature you can change your call schedules in the event you leave early for the day so that your calls run on the overnight schedule. If you decide to come in early for the day, the Skip Ahead feature will let you advance from the overnight schedule to the next business day without having to wait for the clock.

Another great feature is the Multi-lingual Voice Prompt. This gives your callers the option to hear messages or talk to operators in their chosen language. Currently, English, French and Spanish are available.

A new feature available in the DSX v3.2 is the availability to detect spam and other nuisance calls.

When using the Translation Name feature the caller ID is enhanced with additional information about the individual caller. This is great for call center workers; the calls they make will have a custom party number as part of their caller ID (for centers with PRI service). Incoming phone calls can have a custom name show on the caller ID display based on the number they dialed.

Delivering Messages with IntraMail Pro

Never miss a call again. With Follow Me Find Me, if an incoming call comes in while you are away at your desk, IntraMail Pro will ring three alternate phone numbers. In addition to this feature, should you get a voicemail while you are away, IntraMail Pro will call up to five alternate numbers to let you know you have a message waiting.

Your Favorite Features Have been enhanced

NEC has taken their most popular features and enhanced them for better efficiency. For example, the Call Timer can run without a Feature key. You can put frequent calls from colleagues in the Intercom Queue Key- even if you are not an operator. In the past to use your Speed Dial numbers, you could only use them on a separate line or a group line. Now, you can use Speed Dial numbers on your Prime Line. Now you can manually select how you want a number dialed via the Caller ID Log, which puts more control in your hands.

Park and Hold has upgraded the programmable Recall Recycle feature to allow better control of the calls that are placed on hold or park. The Park Recall Enhancement lets you pick up a parked call while it is orbiting or parked.

Introducing New Time-Saving Programs

Instead of eight Ring Groups, there are now THIRTY Department Groups. The Department Groups can be set up as either Ring Groups or Unified Call Distribution Groups (UCD), in any combination. In order to provide a better, more efficient set-up, the group IntraMail programming is consolidated into the Department Groups and it uses a dedicated UCD group so that it does not subtract from the number of Department Groups.

With the new and improved NEC DSX, extensions no longer start at 300. In fact, the Default Numbering for extensions and Department Groups have been organized so that the extension numbers closely resemble the ports they are associated with. (i.e. extensions 301-428 go with ports 1- 128 and extensions 601-630 go with ports 1- 30)
In the new NEC DSX v32 software 3.2 enables all System Administrator Version 3.1 Maintenance and Prompt Update features. This makes it possible to erase, move or copy mailboxes as needs arise. You can also erase pre-installed prompts that don’t serve your needs or if you just need more space.

NEC DSX are complete Voip Systems. Their main function is to enable a company to have multiple phone lines without having to go through the local phone company. The systems use analog and digital lines along with your PC. With one NEC DSX system, a business can have over 64 extensions! They also have such features as incoming call routing, Voicemail, call recording, and programmable feature keys to name a few. NEC made their DSX systems affordable. Don’t think of it as an expense, but an investment.
