NEC has a wide range of phone systems and applications for better business communications.

They offer flexible business communication solutions including traditional PBX systems and cutting-edge VoIP and Unified Communications, plus a wide variety of hybrid options as well.

NEC Offerings and Benefits

NEC are market leaders in business phone systems.

They have designed a range of different products, one of which will suit the scale of your business.

NEC specialises in Voice over Internet Protocol (VoIP) phone systems, meaning that your set-up and ongoing call costs are low, as your calls are made through the internet.

Here are the advantages of getting an NEC VoIP Phone System:

  • Affordable phone system solutions that are flexible, easy to use and have advanced features
  • An auto-attendant function that greets callers and helps connect them to the right department which eliminates the need for an operator or a receptionist
  • A single click of a button and your calls will be recorded so you can keep track of the details of your conversations with clients and partners
  • Call logs mean you can easily see and manage your communications
  • Software-based phone systems are more accessible to update and offer you the room for growth in your business

If you are setting up a new phone system, or entirely replacing your current one, then you will probably need an IP PBX, as well as individual phone handsets.

A PBX is the switchboard that manages incoming calls and creates an internal network so your employees can easily contact each other.

NEC offer both cloud-hosted and physical in-house PBX systems.

NEC In-house IP PBX systems

Physically hosting your telephone system in your office is the more traditional approach, but it can offer more security and faster connectivity than cloud-hosted systems.

This option is a great one if your business has its technical support so that you can purchase the system an have low ongoing costs.

Here are the options from NEC:

NEC SL1100

  • A primary system for small businesses.
  • Up to 64 users, so you can quickly scale up

NEC cloud-hosted IP PBX systems

NEC’s cloud-hosted telephone system Universe 3C is their latest offering.

This system will bring all of your communication channels together, helping your business become more efficient.

Having NEC host your telephone system is a fantastic option if you do not have the in-house capability to support the system.

It gives you the flexibility to change or expand your system, and you will have support for all maintenance and in fixing any issues.

Now you have an idea of the type of system you want; we can move to the handsets themselves.

NECs hones are known for being well designed, and user-friendly, so they should require much staff training.

The options run from your traditional desk phone through to phone software that you operate from your computer:

NEC Desktop Phones

Much like analogue phones, NEC desktop phones look similar but differ significantly regarding capabilities and technology used.

Both can make and receive calls, but NEC desktop phones will allow you to have the benefits of IP telephony as well.

These are the ideal phones to use when you want to update your office communications system without introducing too much complexity or confusing your more traditionally-minded employees.

  • One of the most popular phones that NEC produces, the UT880 combines a traditional phone with a large, tablet-like control screen
  • Hands-free and speakerphone
  • Integrated Bluetooth capability
  • A built-in camera for pictures and video applications
  • Multiple login support
  • USB port

NEC Wireless Phones

Wireless phones do everything a desktop phone can except they are mobile.

They are not wired or connected so you can take and make calls wherever you may be.

With a wireless phone, you are not limited to a specific spot in your office.

NEC makes a range of wireless phones under the DECT category, listed here from most basic to most advanced:

  • G266 – standard wireless option
  • G566 – a mid-range option that links into your Unified Communications system
  • G966 – top of the line phone with smartphone-style screen and capabilities
  • I766 – ruggedised design for tough environments

NEC SoftPhones

NEC softphones have no base units; your office’s phone system plugs directly into your computer, and you control your calls from there.

This is the most modern phone option but can take some people a little getting used to, when we are used to having a physical phone on our desk.

Computer-based phone technology means you can monitor the status of your staff with a glance at the computer screen.

You can instantly know who is available for a phone call and who is not, an excellent tool if you are running a call centre.

NEC phone systems are packed with features to help you get organised and to expand.

Some of the critical features of NEC phone systems are:

  • Headset Compatibility – a headset will allow you to communicate with your staff, customers or suppliers from anywhere in your office
  • Cascade Notifications – when someone leaves a message in your inbox, this function will alert and call you at up to five destinations so that you won’t miss a call
  • Conferencing – with this feature, you can convert voice messages into texts, reply to voicemail using email, answer group chats and instant messaging wherever you are
  • VoIP and Landline Integrations – allows you to expand your business while still maintaining excellent communication quality
  • Ease of Use – NEC phone systems are easy to use and require little training

The Softphone technology you choose will likely depend on what IP PBX system you are using.

  • If you are using NEC’s Univerge cloud-based system, then the UNIVERGE SP350 SoftPhone will integrate with your system entirely.
  • Alternatively, the UC Suite SP310 Softphone will work with any NEC system.
