Hosted Telephone Systems

What is Hosted Telephony?

Seen as the modern alternative to an onsite or on-premise telephone system, a hosted communications system is “hosted” on a cloud platform. This could be a manufacturer or network platform or even your own server hosted in a cloud computing datacentre, for example AWS, Google or Microsoft’s Azure platforms.


Considered by some to be more flexible than an on-premises system, it is ideal for a small business wanting large business features or functionality or even larger businesses that have multiple sites around the country, or a mix of office-based and home-based users. This last point has become even more pertinent with the recent Coronavirus pandemic effectively forcing companies to adapt and offer home working o their employees.   This has seen a rapid increase in the number of users or companies moving to a hosted VoIP phone system.

Perceived benefits are:

  • No upfront equipment costs – as all the main system is already in place in the cloud
  • Flexible management and deployment – adding users requires simple central management and setup and then sending the handset to the user
  • Centralised control by both the provider and end client’s management
  • Features can be added or removed on a user or monthly basis

In comparison to a traditional on-premise telephone system, a hosted telephony solution uses Voice over Internet Protocol (VoIP) technology to deliver voice over data or internet connections rather than using traditional analogue or digital extensions and lines such as ISDN. It is worth noting that BT has indicated that they will be switching off the ISDN network for telephone systems in 2025. Moving over onto an internet-based solution provides the best alternative to this.

How does it Work?

Hosted telephony uses the same data network connections in the office or remotely as office devices such as PC’s and printers to send the voice traffic between devices. Connections from the handset to the cloud-based system are made using secure connections to minimise the risk of fraud or “listening” to connections. Generally, most fibre broadband connections at offices and home are suitable for Hosted telephony as the bandwidth required for a call is only <100k. However, on busy data connections from offices or poor broadband connections e.g., not fibre broadband or leased lines, because voice is a real time application, any interruption or conflicts between data being sent out of the connection can have dramatic effects o nth equality of the voice call. We are all used to crystal clear, always there calls on ISDN or on-premise systems and so therefore, a key component of a hosted telephony solution is a sufficiently good internet connection to allow voce traffic to get to the destination in time and not suffer any quality issues.

Because the handset uses any available internet connection, devices can be deployed in one location and then moved to another, even between countries or continents if users desire to take the office phone with them and providing the internet connection is of sufficient quality, it is like they were in their own office with their own number, voicemail and presence.
