PBX, or Private Branch Exchange, is a telephone system that allows businesses to manage their internal and external communication. PBX systems are used by companies of all sizes, from small businesses to large corporations. They provide a range of features such as call routing and forwarding, voicemail integration with email systems, automated attendant functions for incoming calls and much more.

One major benefit of using PBX is the cost savings associated with it compared to traditional phone lines. With an on-premise solution like PBX there are no long-term contracts or expensive installation costs; instead you pay only for what you need each month in terms of usage fees. Additionally the feature set available through a modern PBX system can drastically reduce overhead costs related to managing customer service operations since many tasks can be automated or handled remotely via web portals provided by some vendors.

Finally, another advantage offered by most modern day solutions is scalability: as your business grows so too does its communication needs – but thanks to cloud based offerings these requirements can easily be met without having any additional hardware installed onsite at your business premises which saves both time & money while also allowing greater flexibility when it comes time for upgrades down the line if needed. All in all this makes an investment into one’s company’s communications infrastructure well worth considering given its potential return over time!
