First, a Review of the Enterprise Communications Market and Key Trends.

Enterprise communications are rapidly evolving as new technology becomes available and as managers and staff adopt new or more streamlined ways of working. 

There are three key megatrends that can be observed in the evolution of enterprise communications:

These trends strongly impact the communications and telephony solutions that companies need to stay competitive. 

Why the OnePhone Solution?

The OnePhone solution is designed to meet the key trends of evolution of enterprise communications, with a focus on communications as a service/cloud coupled with deeply integrated mobility. 

How does it work? 

One Phone is an enterprise-class service replacing traditional PBX, fixed line, mobile and support services. The service enables businesses to dispense with having to invest, upgrade and manage their own company phone system on their customers’ premises. 


  • The private branch exchange (PBX) functionality of the company is realised centrally in the network in redundant managed data centres 
  • The functionality is then available to each user in a device of their preference; usually a mobile phone or smartphone
  • The solution encompasses the functions traditionally provided by fixed-line telephone connections and replaces traditional mobile subscriptions with the tightly-integrated   OnePhone service 
  • The PBX functionality, which in the past was only available at the office desk and on the fixed-line number, is suddenly available on both fixed and mobile numbers, improving workplace mobility

With OnePhone, it is very easy for the company to administer their communications and get a holistic view of total costs broken down by department or individual.

Cloud: The network based service

OnePhone offers all of the benefits of cloud solutions that are produced in centralised, multi-tenant, network-based systems. However, these OnePhone cloud solutions are run in redundant data centres with high performance equipment and economies of scale. Through OnePhone, the ‘cloud’ is implemented and managed to a much higher standard than companies normally experience. OnePhone’s national mobile network is integrated tighter within the network, and telephone calls and PBX functionality are hence available anywhere with the simple usage of the native functions of any mobile phone.

In addition to using mobile phones, other methods of accessing this service includes:

  • Voice over IP desk phones
  • Softphones 
  • Traditional PSTN or ISDN phones
  • Even phones connected to a legacy phone system depending on implementation. 

With just one OnePhone device, a user can choose to have multiple phones connected to the solution depending on needs. Additionally, a number of administrative and call handling user interfaces of the system are accessible using web interfaces.  Standard and advanced PBX and switchboard functions, including call center, and IVR for small and large companies are also available at any location.

Cloud Plus: The onsite mobile network at the company’s premises

In contrast to pure cloud solutions, the OnePhone Cloud Plus solution, as an optional service, can take the call responsibility and performance end-to-end all the way to the phone in the hand of the user. A dedicated 3GPP mobile network can be installed at the customer premises (be it an office, warehouse, factory, store or a combination of these) and can be used with normal mobile phones. Once the onsite, indoor mobile network coverage is deployed, coverage, capacity and high quality are ensured. This enables OnePhone to be used for all telephony needs for all or most employees. In addition, it allows the company to program whether an employee should be limited to using the service only on the company premises or also nationwide. 

The onsite network also offers a layer of redundancy. For example, if the onsite network suffers an outage, the mobile phones, with built in battery backup, can fall back to using the mobile national network coverage. This fall back is instead of continuing to provide telephony service with PBX functionality on fixed and mobile numbers.
