Hosted PBX Telephone System

United Voice Cloud – Quick, Feature Rich, Easy to Deploy B2B Telephone System

United Voice Cloud by United Telecoms is an industry-leading virtual cloud-based business telephony system. By aggregating multiple PBX phone systems into one highly specified centralised PBX switchboard in the cloud, United Telecoms is able to provide our customers with high-end PBX switchboard functionality at a largely reduced cost.

A Hosted PBX Telephone System is a telephony solution where the hardware, which is the equipment acting as the “brains” of the PBX phone system, is moved from an office’s physical premises to a cloud-hosted PBX environment in a data center, and managed by a service provider. The system is suitable for companies of all sizes, offering the same benefits to single users and corporates with 1000+ users. 

Our United Voice Cloud hosted solution combines all the benefits of the leading hosted PBX features found in a modern VoIP – Cloud PBX System. 

Most businesses consider changing to a cloud-hosted telephone system for one or more of these attractive features:

  • Month-to-month contract
  • 30% – 75% reductions on your monthly phone bill
  • Cutting-edge PBX telephony features 
  • Simple setup, easy to customise, quick to deploy
  • Real-time online telephone management system for reporting
  • Industry-leading after-sales service 
  • Mobility – take your office anywhere in the world

Advantages of a Cloud Hosted PABX Phone System

  • Instant setup – hosted PBX systems can be deployed remotely in a matter of days and require little to no in-house training.
  • Cost and space-saving – no switchboard unit or other hardware associated with a traditional on-site PBX telephone system.
  • Instant upscaling or downscaling – user numbers and costs of a hosted PBX system can be adjusted online.
  • Feature-rich solutions – select, arrange and customise the features that your business needs.
  • Online Telephone Management System – take control of your business’ communications solution. View your monthly costs online, in real-time, and assess call trends between staff members and different departments.
  • Indefinite lifespan – no need to enter into a hardware upgrade cycle, as the online technology is regularly and automatically updated to reflect current software releases.
  • Inbuilt call recording – ideal for training and monitoring, all incoming and outgoing calls can be monitored in real-time, recorded and stored.
  • Redundancy – highly resilient data centers house the hosted virtualised solutions, meaning that your telephone systems will not be impacted by power outages or natural disasters at your business premises.
  • Never lose your telephone number again – keep your existing telephone number(s), and maintain communications with existing customers, no matter how often you move, or where you move to.
  • Pure per second outbound voice calling – save money on your call costs and pay for your true usage.

What to Consider when Assessing a Hosted PBX Telephone System

  • Connectivity and associated costs – without a strong, reliable internet connection, the cloud PBX solution will present with poor voice quality. It is therefore imperative that businesses either already have access to a robust internet connection on their premises, or evaluate the associated costs of suitable connectivity when planning a hosted PBX solution.
  • Ownership – ownership of the hosted PBX lies with the supplier. In most cases, ownership will never pass to the end-user, who is merely subscribing to this system.  
  • Failover option – if no broadband internet failover option is provided for, i.e. a secondary or redundant internet connection, any loss in the core connectivity to the hosted PBX will result in users being unable to access the solution.

Hosted PBX Standard System Features

  • User-friendly Browser-based Hosted PBX Interface. This equips you with an admin login and the ability to customise user functionality from anywhere in the world, at any time.
  • Call Recording in the Cloud or On-premises. This can be set to “always on” mode, or toggled on and off by the user as required.

  • Hunt Groups. Create ring groups with intelligence, allowing you to automatically and sequentially move unanswered calls between staff members and departments. 
  • Presence. Granting you the ability to see who is online at a given time via the UCaaS Softphone Platform. 
  • Music on Hold. Simple and easy to configure, you can upload MP3 files to the system as and when required. 
  • CLI (Caller Line Identification). Instantly identify incoming calls, and present your chosen DID (Direct Inward Dialling telephone number) on outgoing calls. 
  • Hot Desking. The ability to ‘move’ your extension with you, regardless of where you are seated, allowing for smart, agile use of your office space.
  • Remote Working. Take your settings with you outside of the office so that you can continue work while commuting, traveling, or working from home.
  • Company Directory. Easily locate and call colleagues with the click of a button.
