Reap the benefits of a VoIP Phone System

Lower Cost

With VoIP telephony, you get to enjoy much lower call charges for domestic or international calls and zero roaming fees.

Also, you can cut your hardware, infrastructure and maintenance costs significantly.

Integrations & Custom Apps

VoIP telephone systems can be easily integrated with third-party systems such as your CRM. Also, there is the possibility to have customized applications developed for you and integrated with your telephone system.

Remote Work

With a VoIP phone system, employees can work from anywhere, such as their own homes, co-working spaces or even from different cities and countries, as long as they have an internet connection.

Scalable & Flexible

Α VoIP PBX is a phone system that is much easier to scale and expand compared to the traditional PBX systems. To expand a VoIP PBX, you only need to add "virtually" more phone lines and extensions to the system!

Less Complex

A VoIP PBX eliminates all the complex hard-wiring of an old-fashioned PBX. Specifically, in the case of a hosted/cloud PBX, all you need is a subscription to a VoIP provider, an internet connection, compatible devices, and you’re good to go!

More Simultaneous Calls

Did you know that you can receive more simultaneous calls with a VoIP PBX? Generally, VoIP PBX phone systems are designed to handle higher call volumes than traditional PBX.
