In the era of remote and hybrid work, seamless communication isn’t just a luxury—it’s a necessity.

Tools like Zoom, Microsoft Teams, Dialpad, and Google Meet have become the backbone of modern collaboration, keeping teams connected across cities, countries, and time zones. But what happens when these tools are accessed through Virtual Desktop Infrastructure (VDI) Workspaces? Can they still deliver the same real-time responsiveness, crystal-clear audio, and reliable performance?

The answer is yes—if your VDI is optimized the right way.

In this blog, we’ll break down:

• How calling apps function on VDI
• Key challenges and effective solutions
• Cloud Flex’s approach to optimizing communication experiences

Let’s dive in and explore how your team can enjoy uninterrupted calls and video meetings—no matter where or how they log in.

What is VDI and Why It Matters for Calling Apps?

Definition of Virtual Desktop Infrastructure

VDI is a desktop virtualization technology that delivers users’ desktops from a centralized server. Instead of applications running locally on a user’s device, everything is hosted and managed in the cloud or a private data center.

Why It Impacts Communication Tools

Calling and video conferencing tools rely on real-time data exchange. For optimal performance, they need:

• Low latency
• High-quality audio and video
• Smooth integration with hardware like microphones, webcams, and headsets

A properly configured VDI environment can support these requirements with minimal performance trade-offs.

Challenges of Running Calling Apps on VDI

1. Audio & Video Latency

Since data travels between the user’s device and the server, there can be a slight delay—especially for voice and video streams.

2. Device Redirection

Redirecting USB peripherals like headsets and cameras is essential but can be tricky without the right policies and drivers.

3. Bandwidth Management

Video calls consume significant bandwidth. Without proper throttling or optimization, jitter and lags can occur.

4. App Compatibility

Some calling applications require special VDI-optimized clients or plugins to ensure stable performance.

How Calling Apps Work Effortlessly on VDI

Optimization Tools and Technologies

• Microsoft Teams Optimization for VDI: Bypasses the VDI server by redirecting audio and video streams directly between clients.
• Zoom VDI Plugin: Allows media processing on the endpoint device, reducing load on the VDI host.
• Citrix/VMware RTME Support: Real-Time Media Engine support improves app responsiveness and media handling.

Audio/Video Redirection

Advanced redirection ensures that devices like webcams and headsets connected to local endpoints function properly inside the virtual session.

Codec Optimization

Using efficient codecs like H.264 reduces bandwidth usage while maintaining video clarity.

GPU Acceleration

When available, GPU on the host enhances rendering performance and ensures smoother video calling experiences.

Benefits of Using Calling Apps in VDI Workspaces

• Consistent experience across devices and locations
• Enhanced security with centralized control and data compliance
• Simplified management of communication tools and policies
• High-quality audio/video even on thin clients
• Anywhere access to enterprise-grade communication tools
