What is Cloud PBX?
A cloud PBX is an internet-hosted phone system that provides business call routing, extensions, and call-handling features without any on-site hardware.
Cloud PBX Explained
A cloud PBX (also called hosted PBX) delivers all the call-routing and call-handling features of a traditional Private Branch Exchange — extensions, call transfer, voicemail, call queues, IVR menus, business-hours routing — but runs entirely on the provider's servers and reaches your team over the internet. There is no hardware to buy, no wiring, and no maintenance; teams just sign up, claim a number, and start calling from a browser or mobile app. Cloud PBX is the backbone of modern VoIP business phone service. Connectoo is a cloud-based VoIP platform with cloud PBX features built in: PBX-style routing and queues, calls placed in the browser via WebRTC or through the iOS and Android apps, and numbers available in 60+ countries. There is no SIM-based calling anywhere in Connectoo. What sets Connectoo apart from cloud PBX and VoIP providers like JustCall, Aircall, Dialpad, OpenPhone, and Exotel is the built-in CRM and multi-channel reach: every call routed through the cloud PBX is logged with native WhatsApp chats and SMS on one customer timeline, and auto follow-up workflows fire across all three channels. Call-only cloud PBX tools cannot unify channels this way. Connectoo serves teams of every size.
