Join for Desktop is a fresh version of our desktop softphone product line which started as one of the first dialers on the market almost a decade ago. Since its inception as a basic, dialpad centric dialer the application has evolved into a fully geared communicator offering an excellent communications experience.

Join is contact centric, showing rich presence information of buddies and allowing instant chat and enriched voice and video calls.

The current version is based on the .NET framework (for Windows), enabling a sleek and elegant user interface with rich customization options.

Both Windows and Mac versions are based on the latest standards for SIP/IMS and other network mechanisms like ICE/TURN peer to peer calling and NAT traversal.

Among other cutting edge technologies WebRTC compliancy is ensured with the HD OPUS codec for audio and brilliant VP8 for video.
