Difference between an on-site PBX system and cloud-based PBX system

Friday, November 6, 2020

A private branch exchange system otherwise known as a ‘pbx system’ is a private telephone network used within an organization. This is such that all the users registered on the system in the organization can communicate with one another and with others outside the organization using ‘Voice over IP’ or VoIP, analogue or Integrated Services Digital Network (ISDN).

Generally, a pbx system is known to run on-site and this over time has gulped in a lot of resources to function. In the light of this, the cloud based pbx system was introduced and there has been quite a lot changes observed. Therefore, this article would be highlighting the differences between an on-site pbx system and a cloud based pbx system. Some of the differences are as follows:

- An on-site private branch exchange system requires installation of a pbx system within an organization. This often takes space and cost a lot in terms of maintenance. The private branch exchange system is expensive and requires frequent maintenance and constant monitoring by pbx experts. However, cloud-based pbx systems are virtual and do not require a physical pbx office in an organization. The pbx system is hosted and run by the Voice over IP providers, thus saving valuable space and reducing maintenance expenses.


- Cloud pbx systems are much more reliable than on-site pbx systems. This is because, cloud pbx systems, is a cloud computing technology on which all the necessary directories required for smooth running of an organizations pbx system have been installed and access to such directories is guaranteed anytime. However, on-site pbx systems are subject to malfunctions due to software glitches or careless personnel handling.


- In case of a fault in an organization’s private branch exchange system, it is quite easier to troubleshoot a cloud-based pbx system than an on-site pbx system. As, it might take the on-site pbx maintenance officers a considerable amount of time to pin-point where the fault is coming from in an on-site pbx, due to the complexity of the system itself.


- Unless your cloud pbx provider is highly trusted, sharing of confidential data cannot be over-ruled in cloud pbx systems, which therefore means, only trustworthy cloud pbx providers should be engaged to provide pbx service in your organization. On the other hand, confidential information remains confidential when on-site pbx systems are used, as the pbx system itself is situated within the organization and managed by employees of the organization.


- The on-site pbx system is a traditional system and it is being phased out of existence at a very fast rate, while cloud-based pbx systems are based on the upcoming cloud computing technology. A very promising technology.


- An on-site pbx system requires an adequate technical knowledge of the installed pbx system. This therefore calls for employment of an adequately trained technical staff, who would be saddled with the responsibility of maintaining the pbx system. However, all that is needed to enjoy the benefits embedded in cloud-based pbx systems, is a subscription to the service providers, who are saddled with the responsibility of delivering seamless pbx service any time of the day.  


- Cloud pbx gives access to full pbx capabilities, without a need for the complex and expensive instrumentation associated with on-site pbx systems.
