Scalable and Reliable Enterprise Phone Systems for Modern Businesses

The education sector has undergone a digital transformation that shows no signs of slowing. Students and staff now rely on consistent wireless connectivity for everything from online assessments to cloud-based learning platforms. However, consumer-grade equipment simply cannot handle the demands of a modern educational environment.

What Is an Enterprise Phone System?

An enterprise phone system represents an elaborate communication platform that is specifically suited to the enterprise environment of larger organisations with 50+ users. Large enterprises have more complex communication needs that distinguish them from a small business solution. Enterprise phone systems need to provide: 

Multi-location management across offices and regions 

Support for remote teams and hybrid workforces.
