How BT can transform your phone system

How BT can transform your phone system

Is your phone system holding you back? Take control with an on-premises system that’s tailored to your needs.

  • Keep costs low

    A powerful service doesn’t have to come at a premium. Choose from two system options to keep your costs to a minimum.
  • Individual direct dial

    Give everyone in your company their own direct dial number and voicemail inbox – with the ability to add extra handsets as your business grows.
  • Better customer communication

    Link to your database so your customer’s name appears when they call, and you can add instant messaging and conferencing for even better comms.

Our phone systems, in more detail

Optional extras

On-hold music and messaging

Choose from a range of options to keep your customers entertained when they’re on hold including: professional greeting messaging, digital memory playback so you can create customised marketing messages, and a fully managed suite of services for total control over your on-hold messaging.

Voice recording

Whether you’re a single user business, SME or corporate, add on call recording services on analogue, ISDN2, ISDN 30 and SIP lines. Choose from a range of options including on-demand, all-call recording, selected extensions and mobiles.

Unified Communicator

With Unified Communicator, you’ll get a screen pop showing all your caller’s details before you answer. It connects your agents’ desktops to the phone system and your database for company-wide visibility and call control.

Secure access control

Access control options from a simple, single button, intercom-based solution. You can access control systems that are connected to either analogue or SIP extensions, and link to BT-installed lock mechanisms, allowing people to control the lock from their handset. We also offer options for internal cameras that display images of visitors on your PC screen for even more security.

Audio visual ringing options

Add extra measures to ensure no call goes unmissed, even in noisy areas where it’s hard to hear the phone ringing. You can add loud rings and flashing lights, as well as paging units so you can make announcements directly from your phone handset, and an interface to connect your existing PA systems to your new BT IP phone system.

Headsets

Communicate more clearly with a wide range of corded and wireless headsets from well-known brands like Jabra and Plantronics, including mono, duo and premium options.

DECT handsets

High-quality cordless phones that use Digital Enhanced Cordless Telecommunications technology, compatible with all of our phone systems including the MiVoice Business and Avaya IP Office.

Structured cabling

There’s no need for independent voice and data wiring when you choose structured cabling, as it accommodates both. Consider structured cabling if you’re moving premises, planning an office refurbishment, changing to an IP phone system, kitting out a new building or greenfield site, or struggling with bandwidth-hungry applications like video conferencing and data streaming.

Training

Learn how to fine-tune your system as your business changes or grows in our Customer Training Portal. We offer 24/7 access to a suite of training courses and video content, available from anywhere – great for remote workers and businesses with multiple sites. We also offer on-site courses if you prefer face-to-face training. 

CallAccountant

Stay on top of every call and control your costs with in-depth data that tracks everything from your busiest times of the day to the cost of outgoing calls by department.

FAQs

Do I have to pay for the system in one go?

No, you can spread your payments out with finance leasing to give you the technology you need, when you need it.

Can I take my number with me if I move?

You can with BT SIP Trunk, as this type of number is on the IP network rather than sitting in the local telephone exchange.

Can I use the system when I’m out of the office or working from home?

Our Remote Worker options ensure your team can stay productive, even when they’re on the go or working from home. You can also use mobile ‘twinning’ so you never miss a call, with incoming calls simultaneously ringing on your desk phone and mobile.

Can BT maintain my phone system?

We maintain the majority of our customers’ phone systems, and all of our new systems include Proactive Remote Monitoring as standard. We’ve got a range of cost-effective maintenance options designed to suit your needs and budget, and we can even maintain your non-BT phone systems.

Can I add extras like voice recording?

We have several phone system add-ons, designed to improve customer service, protect your staff and premises, and increase productivity. Our options include: additional handsets, on-hold music and messaging, voice recording, secure door access solutions, Unified Communicator, and audio visual solutions.

Can my phone system grow with me as my business expands?

We design our phone systems to allow you to grow as a business without worrying about system capacity. They’re built with your growth in mind, with the ability to add additional lines and extensions as well as extra functionality like voice recording.

Will I be able to make SIP calls on my phone system?

BT phone systems like Avaya IP Office and Mitel MiVoice are compatible with BT Cloud Voice SIP. But if you have another phone system, you can still take BT Cloud Voice SIP by using our BT SIP Trunk Gateway.
