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, call routing, and internal team messaging 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 — the same softphone even places and takes calls inside WhatsApp, and your team messages each other in threaded channels with live presence in the same workspace.
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. |
| Team chat channels | Internal channels with threaded replies, message search, and live presence, in the same workspace your agents take calls in — so a shift handoff or an escalation never has to leave Orbit for a separate chat app. |

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.
- Can I keep my current carrier?
- 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?
- No. The visual IVR builder is a drag-and-drop canvas — you route callers by keypress or spoken intent to a named queue or agent without writing dial-plan code.
- Can the same phone system place WhatsApp calls?
- Yes. The operator softphone places and receives WhatsApp Business voice calls alongside PSTN lines, with calling permission set per contact, per-destination minute metering, and a dedicated WhatsApp call log.
