Cloud phone system features

  • “Out-of-the-box” cloud phone system

    Our standard Hosted PBX package includes everything you need to run your phone system in the “cloud” through your internet or mobile data connection.

    Make & receive calls using either an IP phone or PC softphone, or via your mobile phone using our Luna app (iOS and Android).

  • Don’t pay for stuff you won’t use

    Unlike other Hosted PBX providers we won’t charge you for features you won’t use.

    But, as your business grows, you might want to add more advanced call management capabilities to your platform. Our suite of Hosted PBX features can be bolted on as and when you need them. So you only pay for what you’re using at any one time.

  • James Lester
    Director - Carpet Bright UK

    We’ve been using Numbergroup’s cloud-hosted communication platform since 2016. Their cloud phone system is reliable and easy to use, plus they have extremely competitive call rates, friendly customer service and faultless support. Our switch to Numbergroup saved us over £800 a year! We highly recommend Numbergroup to all our business partners and clients.

Features included in Basic Cloud Phone Package

  • Make & Receive Calls On Your Smartphone

    Use your mobile phone to make & receive business calls with our Luna PBX App. Keep your business and personal calls separate by displaying your business number caller ID. The ideal solution for busy freelancers and remote workers.

  • Transfer Calls Easily

    Transfer calls to other extensions or even different phone numbers, regardless of where you or your employees are located. Choose to do either a “supervised” transfer where a conversation can take place privately before the caller on hold is connected to the new destination, or a “blind” transfer where the call is transferred with no intervention.

  • Personalised Voicemail

    Record personalised voicemails for each member of your team. Allow staff to instantly retrieve and listen to call messages.

  • Choose Your On-Hold Music

    Entertain your callers with any music of your choice while they’re waiting to speak with you.

    Hold conference calls with staff on or off-site. Arrange board meetings between sites across the globe or invite your clients and suppliers to a conference call. Have the flexibility to configure any UK number for conferencing and ensure security by providing PINs to attendees.

  • Hosted Phonebook

    Save time & energy by adding important contacts within your group phonebook to ensure everyone within your organisation has access to important phone numbers.

  • Virtual Call Queue

    Receiving more calls than you can comfortably answer? Reduce call abandonment and frustration by placing waiting callers in a virtual queue where they can listen to music, find out queue position and be reassured their call will be answered.

  • Record Incoming & Outgoing Calls

    Record all or some of your incoming and/or outgoing calls. Includes the ability to pause a call recording and resume it, which is essential for PCI DSS Compliance if taking payments over the phone. We’ll also store your recordings securely for you to retrieve as and when required.

  • Voicemail to Email

    Get voicemail messages delivered to you by email as an MP3 file. Listen to voicemail message son the go without having to go through a complicated dial-in process.

  • Fax to Email

    Accept faxes without having to buy a fax machine. Choose any UK number to use as your fax number and receive faxes instantly by email as a pdf attachment.

  • Time of Day Routing

    Select different number translation and routing options for different times of the day on any day of the week.

  • Call Whisper

    Play a short audio prompt to the answerer of the inbound call announcing which number has been dialled.

  • Missed Call Notifications

    In the event of a missed call, we’ll notify you automatically by email. Choose to send to individual email addresses or a centralised mailbox.

  • Multi-level IVR

    Automate the process of directing callers to the correct department, site or give callers options to find out more about your business without having to use up manpower. We can create, upload and configure a professional bespoke IVR message of your choice.

  • Hunt Groups

    Distribute phone calls from a single telephone number to a group of several phone lines. Apply a weighted algorithm to select which line will receive the call.

  • Fraud Prevention Tools

    A suite of tools to monitor, detect and minimise potential telecoms fraud occurring on your account.

  • Call Analytics

    Get access to a suite of analytics that show you how each of your inbound numbers are performing. Use the data to refine your future promotional campaigns and get better ROI on your marketing spend.

  • Webhook Integration

    Connect your SaaS platforms to our portal via webhooks, allowing information to be automatically shared between both systems.

    It’s been almost a year since we started using Numbergroup’s cloud services. Since the start they’ve made our lives easier by providing proper solutions, not just work-arounds.

Questions about our cloud-hosted PBX platform

  • What services are included in the Basic Hosted PBX account?

    You will have access to all the basic features you need to manage incoming & outgoing calls via the cloud. Our Basic Hosted PBX package is an “out of the box” solution to get you up and running without any hassle. It includes the following:

    What services are included in the Basic Hosted PBX account?

    • Pre-configured Luna PBX app (make calls & accept calls on your mobile phone)
    • Call transfer
    • Music on hold
    • Connectivity to IP handsets & softphone applications
  • Is there a minimum contract period? If yes, what is penalty for cancelling early?

    Unlike most of our competitors, we don’t enforce a minimum term contract on the Hosted PBX service. We would prefer customers to continue using our services out of choice, not contractual obligation.

    Should you decide to close your account, we require 30 days written notice to be sent to suppport@numbergroup.com, along with payment of any outstanding balances.

  • Can I get a Hosted PBX account for personal (non-commercial) use?

    Our services are designed explicitly for business use only so we’re unable to offer accounts to individuals or for domestic/residential use.

  • Is the Hosted PBX account only available to UK customers or worldwide?

    We welcome businesses from all countries to sign up to our Hosted PBX service. Because of our global carrier network, we’re also able to offer very competitive international call rates.

  • Our business has huge volumes of calls. Are you open to negotiating discounted call rates?

    The Basic Hosted PBX package comes with a bunch of inclusive minutes. If this isn’t enough for you, we suggest you discuss your specific requirements with your account manager. We’re a network operator, not a reseller, so we can offer local & international call rates and services at the most competitive prices.

  • What if we need some bespoke functionality. Can you build this and will you charge us?

    Bespoke services and features can be built on request. However, the lead time and cost (if any) will vary depending on the feature type and order of priority.

  • Reliability and Call Quality

    Our cloud-based system handles millions of calls every month for thousands of businesses all over the UK. Our network is hosted across multiple secure data centres sites with built-in automatic disaster recovery and failover. Over the past 10 years, we have maintained a 99.9997% uptime.

    As our service is broadband agnostic, you can use any internet connection to access it. If your broadband drops for any reason, we can automatically build in failover diverts to keep your business and phone calls operational, even with home-based working employees.

    The quality of a call is similar, if not better, to that, you find on a regular landline telephone service. We can often offer “High Definition” quality on calls.

    The biggest factor that affects call quality is your internet connection and the bandwidth you have available. In most cases, telephone calls are prioritised over your broadband connection, so your calls should remain clear even if your internet connection is choppy.

    We will discuss your requirements during the signup process to advise on bandwidth requirements. Still, in most cases, a standard UK fibre connection is enough to run anything from 1-20 calls simultaneously without any issues.

  • Why Switch?

    Why switch to our cloud PBX over your existing telecommunications infrastructure?

    Firstly and most importantly, cost.

    Whichever provider you are using, you are throwing money down the drain on line rentals, connection fees, “premium” support and overpriced calls every month.

    We have invested millions over the last 20 years in building in-house software and hardware, so you don’t have to. Our solution doesn’t require hardware, data centre, computer rack, cabling or technical staff to maintain and run it.

    Secondly, usability.

    Our system is significantly more reliable and robust than anything you currently operate, and should there be a fault of any kind; we will be aware of and fix it remotely before your business is affected.

    Our cloud PBX has many features that allow you to easily handle caller demand, office set-up, or specific working practices. You can switch features on and off as you need to.

    Among the many advantages, you get with our cloud PBX is the ability to allow people to use the system from home, abroad, car or hotel.

    The system creates a unified virtual platform, which means calls are made, received, and transferred to make it appear that your entire team is in the same office as you and your callers. You can monitor and track usage no matter where your colleagues are working.

    Thirdly, scalability.

    Start small, grow bigger…. then grow even bigger. Our cloud PBX works as smoothly for a small start-up as it does for a large, multi-department corporation with offices worldwide.

    You can add users to our PBX in an instant. No new telephone cables or sockets are necessary – so none of the engineering work accompanies a phone upgrade.

    Moving premises?

    So long as the new place has broadband, you’re ready to go.

    And scalability works in all directions.

    Got more people? Expand your PBX to accommodate.

    Let some people go? Reduce accordingly.

    Is an extensive new marketing campaign about to start? Take on the capacity and the features you need. When the campaign’s over… cancel them.

    We’ll beat any price or quote, guaranteed! let’s have a chat to discuss your requirements.

    We have no contractual tie-ins meaning you can walk away whenever you want. When you join Numbergroup, you become more than just another account number. You become part of our little family. We’ll do everything to support your business no matter what. Take a look at our Customer Charter for more info.

  • Easy to Setup?

    Luna, our cloud-based phone solution, is designed for ease of use and requires no technical knowledge and can be operational within minutes, ready to make or receive calls.

    Suppose you decide to purchase one of our physical desktop phones. In that case, these will auto-configure when powered on and plugged into any internet connection, with your employee’s extension and phone number ready to use.

    The mobile app is configured via a QR code which we can send to your employees via email or liaise with your IT department. To complete the setup simply scan the QR code with a smartphone camera, iOS and Android supported.

    For employees using a PC/Laptop, we have a Windows/Mac desktop app

    As we are hardware agnostic, If you already have some existing IP phones, these can be configured manually to connect to our service.

  • What is a cloud based phone?

    A cloud-based phone is a software-based telephone program that connects via any internet-connected device to allow your employees to make and receive calls from anywhere in the world. Because it’s internet-based, there’s no need for any ISDN or traditional fixed telephone lines.

    With a cloud-based phone, your employees can work from wherever they choose; all that is required is a regular-looking desktop Phone, smartphone or laptop/computer with a decent broadband connection or Wifi. This connects virtually to your cloud-based PBX system just as if they are located within a regular office.

    All the maintenance, configuration and updates are handled remotely via our customer website portal, updated in real-time with a click of a mouse. This allows you to configure how your phone system works and how calls are answered and transferred between your departments and employees.

    In short, this equates to lower upfront costs, zero maintenance, a highly customisable and functional service, and plug-and-plug ease of use.

    It’s the perfect solution for a remote, hybrid or WFH workforce, and your staff remain connected no matter their location or timezone.
