What is ‘PBX in the cloud’?
If you’ve used Google Mail or Docs you’ve been using cloud computing. With Google Mail the email inbox doesn’t actually reside on your computer, it is located on one of Google’s servers and you access it via the internet. Similarly with Google Docs, you don’t even have to have Word or Excel on your computer in order to create documents and spreadsheets because you are accessing Google’s hosted version of the software.
Initially cloud computing was limited to data applications, but with the evolution of VoIP voice services are now also available via the cloud.
Do I need a hosted or private cloud?
Hosted solutions are housed with your telecommunications service provider. You don’t need to buy, install and maintain the PBX equipment itself if you take this option. Rather your equipment is located in the telephone company’s exchange and you use it on a contract basis. It’s updated automatically, and is cost-effective, because you only pay for what you use.
A private cloud is the best option for companies who prefer to keep their communications infrastructure within their own technical environment. All the call cost savings and features of a hosted solution are still available, but you’ll need to buy the infrastructure and pay for updates and maintenance. Financial institutions and large corporates usually prefer this option.
