OBS Studio Recording: How to Capture VoIP Calls and Screen Shares for Better Training and Support

When you need to record a OBS Studio recording, a free, open-source tool for capturing video and audio from your computer. Also known as Open Broadcaster Software, it's widely used by support teams, trainers, and remote workers to document calls, demos, and troubleshooting sessions. Unlike built-in screen recorders, OBS gives you full control over audio sources—like your VoIP app, system sounds, and microphone—so you can capture crystal-clear call audio without background noise.

Recording VoIP calls with OBS isn’t just for training. It’s how teams fix recurring issues, audit compliance, and improve customer service. You can record a SIP call capture, the process of capturing voice traffic from a Session Initiation Protocol-based phone system while simultaneously showing the screen of your CRM or BIM software. That way, you see exactly what the agent saw when they helped a client. Many users pair OBS with screen sharing recording, capturing live visual content shared during a VoIP call to build a library of real-world examples for onboarding new hires or reviewing SLA responses.

But it’s not plug-and-play. If you record only your microphone, you’ll miss the other person’s voice. If you record system audio alone, you might pick up background music or notifications. The trick is to use OBS’s audio mixer to add both your VoIP app (like Zoom, RingCentral, or FreePBX) and your headset mic as separate sources. Then, mute anything else. You’ll get clean, isolated audio that matches what the customer heard. Most users set the output to MP4 or MKV at 1080p and 60fps—high enough for detail, low enough to save space.

People forget one thing: recording calls isn’t just about saving files. It’s about making them useful. That’s why top teams tag recordings with dates, customer names, and issue types. Some even use OBS’s scene switching to auto-start recording when a call begins—using a hotkey or automation tool. And yes, it works on Linux, Windows, and Mac. No subscriptions. No hidden fees. Just a tool that does exactly what you need.

What you’ll find in the posts below are real setups, common errors, and fixes from teams who’ve been there. You’ll see how to sync OBS with SIP clients, avoid echo from speakers, handle bandwidth limits during screen shares, and export recordings that play back smoothly on any device. No fluff. Just what works when your call quality matters.
