A PBX (private branch exchange) is a telephone system that is used within an organisation, allowing all users to share a certain number of external phone lines with a certain number of internal ones.
3CX (see www.3cx.com) is a very powerful VoIP telephony and has become the first PBX to become available on the Google Marketplace. Google Marketplace is the official online store for third-party software and web applications.
So, from now on, it is far easier to perform Google Cloud installations of this incredibly powerful telephone system.
At 121 IT Services we recommend 3CX as our phone system of choice.
