A Complete VoIP Phone System — Powered by a Single Interface

Most communication systems are a collection of separate apps. Zultys is different.

At the core of the platform is ZAC (Zultys Advanced Communicator) — a single interface that unifies voice, video, messaging, SMS, and collaboration tools into one consistent user experience across desktop, web, and mobile.

  • Make and receive calls, manage voicemail, and control call routing
  • Send SMS and instant messages from the same interface
  • Launch video meetings and screen sharing sessions instantly
  • Access presence, directories, and team collaboration tools
  • View customer data through CRM integrations and screen pops

Instead of switching between applications, your team communicates entirely within ZAC — reducing friction, improving response time, and keeping every interaction connected.

Work Anywhere with Mobile ZAC — Your Mobile Business Phone System

Work is no longer tied to a desk, and Mobile ZAC ensures your communication system isn’t either.

With Mobile ZAC, your smartphone becomes a full extension of your business phone system. Employees can access the same interface, features, and functionality they use in the office—without compromise.

Calls, messages, presence, and directories stay synchronized across devices, allowing users to move seamlessly between desktop and mobile while maintaining a single business identity.

Whether your team is remote, hybrid, or constantly on the move, ZAC ensures they remain fully connected and fully capable.

Built for Real Business Operations — Inside One System

ZAC is not just a communication tool—it’s the operational interface your team works from every day.

Customer service teams use it to manage queues, respond to calls, and monitor activity in real time. Sales teams rely on it to initiate and capture customer interactions with CRM integrations. Internal teams collaborate through messaging, file sharing, and video—all within the same environment.

Because everything happens inside ZAC, your team maintains full visibility across conversations, customers, and workflows without switching tools or losing context.

In higher-demand environments, Zultys extends this same interface into a full contact center solution—handling calls, SMS, and web chat within a unified system, complete with reporting and supervision tools.

Flexible, Reliable Infrastructure — Cloud, On-Premise, or Hybrid

Zultys gives you the flexibility to deploy your system in the way that best fits your business—without sacrificing performance or consistency.

Whether hosted in the cloud, deployed on-premise, or configured as a hybrid solution, the platform delivers the same interface and feature set. This allows you to choose the right infrastructure today while maintaining the flexibility to evolve over time.

Behind that flexibility is a resilient architecture designed for continuity. With geo-redundant data centers, built-in failover, and continuous monitoring, your communication system remains operational even during outages or disruptions.
