UCaaS — a cloud phone system with IVR, trunking, and queues built in
What is Unified Communications as a Service?
UCaaS (Unified Communications as a Service) is a cloud-delivered business phone system that unifies calling, voicemail, and call routing without an on-site PBX. Orbit runs your whole inbound voice operation — a visual IVR builder, SIP trunking with bring-your-own-carrier, ACD call queues, and voicemail with branded greetings — and the same softphone even places and takes calls inside WhatsApp.
What UCaaS on Orbit includes
| Capability | What you get |
|---|---|
| Visual IVR builder | Build call menus on a drag-and-drop canvas and route callers by the key they press or the intent they speak, straight to the queue or agent you pick by name. |
| SIP trunk BYOC | Keep your existing carrier and numbers over SIP while getting a modern phone system — with live visibility into every registration and call so you can spot issues fast. |
| ACD call queues | Queue inbound calls and distribute them by skill, priority, and business hours. A caller on hold can keep their place and take a callback instead of waiting on the line. |
| Voicemail, greetings & warm transfer | Record branded greetings per box, capture voicemail with a transcript and summary, and warm-transfer a caller to a colleague with music on hold while the consult leg connects. |
| WhatsApp Business Calling | Place and receive voice calls inside a WhatsApp conversation on the same softphone your team uses for PSTN lines, metered per destination minute with its own call log. |
Common use cases
Replace an aging PBX
Move your business phone system to the cloud — IVR, trunking, queues, and voicemail — without buying or maintaining on-site hardware.
Bring your own carrier
Keep your existing carrier and numbers over SIP while gaining a modern IVR, queues, and a softphone your team can use anywhere.
Add WhatsApp calling
Let customers reach you by voice inside WhatsApp on the same softphone, so a chat can escalate to a call without switching apps.
UCaaS — frequently asked
- What is UCaaS?
- UCaaS stands for Unified Communications as a Service — a cloud-delivered business phone system that combines calling, IVR, call queues, and voicemail in one platform, so you do not run an on-premise PBX.

- Yes. Orbit supports SIP trunk bring-your-own-carrier: register your PBX or authenticate by IP, keep your carrier and numbers, and monitor every registration and call attempt on a live panel.
- Do I need to write dial-plan code to build call flows?
