Businesses nowadays aim to be more flexible than ever before, and this includes telephony enterprises. While in the past, it was essential to have a local PBX, the trend is currently moving towards cloud-based solutions. In this context it is important to note the essential technical differences between the two models, IP centrex and managed PBX.
The term Centrex is derived from Central Office Exchange. It refers to a physical system made available by a provider and used by all of the provider’s customers. Operational and maintenance costs are shared by all users, making it considerably more economical for the individual companies, who pay a fixed monthly price per workplace/extension. A company sources all of its telephony and its telephone system from just one provider. The advantages are clear to see:
▪ Maintenance and updates are carried out automatically
▪ Different solutions, such as basic, comfort and premium, can be easily booked and cancelled as needed
▪ System operation and administration are designed to be as simple as possible
A managed PBX is of more interest to companies who want an individual solution. In this case it is a cloud-based telephone system only accessible to the company and its staff. This enables a level of customization that is not possible on shared servers.
There are however disadvantages – maintenance and update tasks must be carried out by the company itself, and the overhead for administration must also be calculated, which can be cost-prohibitive for small and medium-sized companies.
