Cloud PBX
A cloud phone system: extensions, SIP trunking and call routing for your company, hosted on AWS and dedicated to your operation.
Unified communications
Hal-AI UCS Cloud
Everything you expect from an advanced cloud telecom server.
Phone system, CRM, WhatsApp channel and artificial intelligence on the same server. The call and the text conversation happen inside one operation, with one customer history and one agent answering.
Infrastructure on AWS. WhatsApp channel on Meta's Official Cloud API.
What is inside
Four components, one server
Hal-AI UCS Cloud brings telephony, customer relationships, automated service and artificial intelligence together on a single platform — with no need to stitch four different vendors together to keep the operation running.
CRM & Sales
A CRM with a sales pipeline built into UCS Cloud. The customer record, the history and the funnel live exactly where the conversation happens.
Automated service and WhatsApp campaigns
Hal-AI Zap messaging built in, running a WhatsApp channel: automated service, human takeover and outbound campaigns.
Multipurpose AI core
The same intelligence applied to chats, records, business flows and external processes — not just to answering messages.
This is not a chatbot running a flow. It is an operational agent trained to do the work.
This is how the phone system looks to the people running it: extensions, queues, SIP trunks and calls in progress on one screen — and, right next to them, the call that just ended turning into a CRM record.

Call attachments
The screen brings together everything the phone system has to show at once: the extensions with their department, queue and status — 2045 is the virtual receptionist answered by the AI, 2011 is on a call, 2031 is on break —, how many callers are waiting in each queue, and the health of the three SIP trunks, with the backup trunk ready to take over if the HQ trunk drops.
The chart shows calls hour by hour through the day, adding up what the AI answered and what went to the extensions, and the blue strip below follows the call that just ended. That call turns into a CRM record on its own: contact created, turn-by-turn transcript attached, pipeline stage set, and the phone conversation sitting on the same timeline as WhatsApp.
Advantages
Why UCS Cloud
Four product decisions that change daily life for anyone running customer service over the phone and over messaging.
An advanced PBX, configurable and dedicated
An advanced PBX hosted on AWS infrastructure, fully configurable and dedicated to your company. The system is yours: routing rules, extensions and business hours follow the operation you already have, with no hardware to maintain in a server room.
WhatsApp built in at no additional cost
Hal-AI Zap messaging comes built into UCS Cloud at no additional cost, running a WhatsApp channel. Your official number lives on the same platform as your telephony — and the message history sits right next to the call history.
A CRM whose pipeline is part of UCS
The CRM is not a separate system someone updates after the fact: the sales pipeline is built into UCS Cloud. Who called, who wrote in, what stage they are at and what was already agreed all live on the same record.
An AI core that goes beyond chat
The artificial intelligence core is multipurpose and can be applied to chats, records, business flows and external processes. The same AI that answers the customer also queries systems, organizes records and runs routine work.

Voice and text
The call and the conversation in one flow
The customer dials your number and the artificial intelligence answers in real time: it talks, queries the connected systems, transfers the call to a person and hangs up.
It is the same brain that handles text — same prompt, same tools, same long-term memory. Switching channels does not mean reconfiguring a bot, and the customer who called yesterday does not have to repeat the story on WhatsApp today.
- The AI answers the call, holds the conversation and transfers when it makes sense
- If a file needs to go out, the same agent reaches for the company's WhatsApp
- Live calls and phone history visible to the supervisor
- Turn-by-turn transcript of every voice interaction, ready for auditing
- Extensions and trunk registration status in the SIP channel registry
Migration
Built to replace the PBX you run today
UCS Cloud was designed to take the place of the traditional phone system installed at your company — and of any other cloud PBX that only does telephony.
Traditional PBX or ordinary cloud PBX
- Hardware in your building, with maintenance and a physical ceiling on growth
- Telephony in one place, WhatsApp in another, CRM in a third system
- Call history kept apart from the text conversation history
- Artificial intelligence, when it exists at all, is a module sold separately
- Every integration turns into a project and depends on a different vendor
Hal-AI UCS Cloud
- An advanced PBX on AWS, fully configurable and dedicated to your company
- Telephony, WhatsApp channel and CRM on the same server
- Calls, messages and the customer record on one timeline
- A multipurpose AI core included, useful well beyond chat
- Your ERP's APIs become tools the agent uses, without leaving the platform
Discovery
We map extensions, queues, business hours and everything your current system does — including the workarounds nobody wrote down.
Setup
Cloud PBX goes live on AWS with your numbering plan, the SIP trunk is registered and the extensions are provisioned.
Channel and agent
The WhatsApp channel is activated through Meta's official flow, and the agent receives its personality, knowledge and tools.
Go live
Queues, operators and supervisors come online; the AI answers and the human team takes over the conversation whenever they choose.
One operation
WhatsApp, CRM and telephony, fully integrated
The value of UCS Cloud is not having all three capabilities: it is having them talk to each other inside the same server, on the same customer record, with the same visibility into who handled what.
One customer, one timeline
Tuesday's call, Thursday's message and the card on the funnel all belong to the same person. The supervisor opens the record and sees the history by channel, the sentiment the AI detected and the tags generated from the latest messages — with natural-language search across the whole base.
Human and AI in the same chat
Taking over a conversation pauses the bot automatically; closing it hands service back to the agent. No parallel thread, no lost history.
Queues, operators and supervisors
A complete call center structure, with break types, per-queue supervision scope and real-time monitoring of every open chat.
Campaigns that protect your number
WhatsApp campaigns are built and tracked on a kanban board, with audience segmentation and per-campaign reporting.
While they run, the guardian watches the health of your official number: it freezes sending when quality drops, slows the pace as spam limits approach, and shelves any recipient that returns an error.
The systems you already run
The REST APIs of your ERP, health record or order system become tools the agent can use: it queries and acts in that system during the chat or during the call. There is also support for MCP servers and a versioned Hal-AI public API, authenticated by key and scoped per resource.
Questions
Frequently asked questions
Does UCS Cloud replace the phone system we already have?
Yes. Hal-AI UCS Cloud was built to replace both the traditional PBX installed at your company and any other cloud PBX. It is an advanced PBX hosted on AWS, fully configurable and dedicated to your operation — and it brings the CRM, the WhatsApp channel and the AI core along with it.
Is the WhatsApp channel included?
Yes. Hal-AI Zap messaging comes built into UCS Cloud at no additional cost, running a WhatsApp channel. Hal-AI is a Meta Business Partner and operates on the Official WhatsApp Business Cloud API, with activation through Meta's authorized flow and official templates created inside the platform itself.
Does the AI really answer phone calls?
Yes. The customer calls and the AI answers in real time: it talks, queries the connected systems, transfers the call to a human and hangs up. It is the same agent that works on WhatsApp and webchat, with the same prompt, the same tools and the same long-term memory — the technology covered by the patent filed with the USPTO in 2025. Every voice interaction is logged with a turn-by-turn transcript.
Can I connect UCS Cloud to the systems my company already runs?
Yes. The AI core is multipurpose and applies to chats, records, business flows and external processes. The REST APIs of your ERP, health record or order system are registered with their endpoint, authentication and description, and become tools the agent uses while serving the customer. There is also support for MCP servers and a versioned Hal-AI public API for teams that prefer to integrate from their own side.
