Cloud PBX or VoIP?
Terminology can be confusing, but it is rather easy to decide what you need. VoIP simply refers to making calls over the Internet, while a Cloud PBX is a complete office telephone system which includes a VoIP line for making cheaper calls.
So if you already have an office telephone system and only want to make cheaper calls, then choose VoIP. If you do NOT have an office telephone system (PBX) or would like to move your telephone system to our cloud, then choose Cloud PBX.
