Products used

Türk Telekom, one of the largest telecommunications providers in the EMEA region, modernized its internal communications by replacing its old communications platform with Zoom. By adopting Zoom Node, the company successfully maintained control over its data infrastructure while significantly improving collaboration and user experience across its 20,000+ employees.

A Need for Change

As its existing communications platform is quickly becoming obsolete,Türk Telekom sought a secure, scalable alternative to support a company-wide rollout, provide end users with a modern communication and collaboration experience, and comply with strict regulatory requirements. The IT department set out to find a platform that would:

Seamlessly integrate with existing video conferencing endpoints
Scale across a large enterprise
Keep meeting media traffic and recordings within the organization’s data centers

The organization’s requirements reflected the scale of their operations and their sensitivity to compliance, performance, and user experience, especially in the context of being both a telecom service provider and a highly regulated entity.

Why Zoom: A Hybrid, Scalable, Privacy-Conscious Solution

After evaluating various options, Türk Telekom selected Zoom Workplace, primarily due to its hybrid deployment capabilities provided by Zoom Node. This architecture allowed Türk Telekom to localize key communications infrastructure components, such as media processing and recording, while benefiting from the scalability, advanced collaboration features, and intuitive design of Zoom’s hybrid platform.

We needed our media to stay in our data centers, within the country,” said Hakan Tongar, IT Operation Director at Türk Telekom. “Zoom Node was the perfect fit.

Zoom Node’s Meetings Hybrid, Recording Hybrid, and Team Chat Hybrid service modules gave Türk Telekom the control it needed to meet internal privacy and data protection requirements without compromising on usability, performance, and features such as the hybrid room interoperability. This allowed Türk Telekom to utilize existing video conferencing devices, protecting the investment in the hardware for existing meeting rooms.

Deployment and User Experience

The transition to Zoom was smooth and did not cause any service interruption for the end users. Despite local processing and network latency concerns, the IT department reported no performance issues post-deployment.

People don’t even know they are using Zoom Node or the cloud,” Alper Arpacıoğlu, Enterprise Support Operations Senior Manager, shared. “There’s no latency, no connection issues—just smooth operation.

This seamless experience helped accelerate adoption across internal teams, building trust in the new service and reducing resistance to change.

The Impact: Increased Adoption and Improved Collaboration

Since the switch, Türk Telekom has significantly increased employee engagement with the platform. Compared to the legacy platform, Zoom has shown dramatically higher usage rates across the organization. In particular, there’s been a noticeable shift in behavior—from audio-only meetings and standalone chat sessions to multi-modal video conferences, interactive whiteboarding, and integrated feature-rich team chat.

With our old communications platform, most people only used audio conferencing. Now, they’re actively using video calls, whiteboard features, and team chat,” Onur Temel, Active Directory and UC Manager, explained. “The communication quality has improved, and so has the user experience.

Teams that previously relied on consumer messaging apps like WhatsApp for group communication have now migrated to Zoom, reinforcing the organization’s data governance standards and improving overall collaboration consistency and compliance.

Future Outlook: Strengthening Control, Enabling Growth

Türk Telekom’s adoption of Zoom Workplace enabled by Zoom Node reflects a strategic shift toward a hybrid, privacy-centric communications infrastructure. By retaining enhanced control over data flow and processing while accessing advanced hybrid features, the company has complied with internal policies and set the foundation for a scalable, state-of-the-art, future-proof collaboration environment.

While the deployment has focused on internal communications, Türk Telekom’s connection to TT Ventures—its innovation and investment arm—positions the company well to explore broader applications in the future, and the groundwork laid with Zoom Node provides the flexibility to expand.

The success of the Zoom implementation—driven by increased adoption, feature engagement, and user satisfaction—reinforces Zoom’s position as a trusted, long-term technology partner for large enterprises navigating the complexities of modern unified communications.
