3CX Phone System 12 – SP 6 Adds Clientless WebRTC Web Meetings

Version 12 SP6 is no longer available for download. To download the updated version click here.

Much more than a service pack, SP 6 brings a host of new features including clientless web meetings by leveraging WebRTC technology, a new management console, support for Fanvil IP Phones, a brand new SBC functionality and an update for our Android, iPhone and Windows clients!

We have worked around the clock to bring this update to 3CX Phone System, which will revolutionize the way we communicate with our customers and colleagues!

Clientless web meetings using 3CX WebMeeting and WebRTC

3CX Webmeeting now features Google’s new WebRTC technology, and makes 3CX one of the first vendors to bring a clientless web conferencing solution without the need of Java, Flash or any plug in to participate in the meeting! Launch web conferences with screen sharing and video within a few mouse clicks!

This functionality is currently in beta, and for now you can schedule meetings using 3CXPhone for Windows only. We will add the ability to schedule meetings from other 3CX clients in the next update.
