Dealing with the disadvantages of PABX

The objective of this article is to help your business overcome the limitations and disadvantages that comes with the standard on-site PBX system or helps design an optimal network infrastructure for fast and efficient communication.

Though the on-site PABX system has made businesses communications much more efficient and effective since its development, it still has some disadvantages.  These disadvantages deal with various aspects of the system like cost and maintenance. This article lists some of the disadvantages of a PABX system and how to deal with them.

The most obvious disadvantage is its dependence on a constant power supply. Dealing with this requires proper planning and designing of your network infrastructure to minimize power consumption, and proper cabling to avoid power outages due to improper wiring. It is highly recommended to invest on a generator and UPS equipment to be able to attain continuous communications for a certain time. An alternative instead, would be to invest on a virtual PBX system since it doesn’t require PBX equipment to function.

The standard on-site system does not provide communication connectivity to a mobile workforce. This limits the capacity of businesses with a considerable amount of travelling employees. A solution to this is to upgrade to an IP PBX system with integrated VoIP GSM Gateways installed.

Installation and configuration of the standard system incurs a huge investment cost. Aside from acquiring the equipment, the initial set-up and configuring of the devices takes a considerable amount of time and money. This can be mitigated by the use of virtual or cloud PBX applications, or by designing an optimal network infrastructure that does not include unnecessary equipment.

Another hindrance to business productivity is upgrades and maintenance downtime. During this time, the system is shut down resulting to considerable profit loss for a company. A solution to this would be to implement scheduling for upgrades so that only a part of the system is shut down. A back up system or server could also be implemented while the other ones are being updated. This yields no downtime but requires a larger investment for additional equipment.

The last disadvantage on this is the list of restrictions and scalability limitations. Network devices usually have a life of up to 5 years before it requires replacement. It also takes 2 to 3 years before a business requires line expansions. This entails the purchase and installation of additional equipment to support new users which requires considerable budget allocation. However, by this time your previous system is already outdated and not fully compatible with the new devices on the market. Next thing you know, you will be maintaining multiple system platforms thus increasing stress and maintenance costs. This can be avoided by adopting a virtual or cloud PBX system, or by properly designing and purchasing equipment that are highly scalable with backwards compatibility.
