SLP  Updates for all products online

Today, we have released updated versions for all products. Besides some changes under the hood, we’ve added some new features:

All products:
A new button is available to toggle IPv6 support. This was necessary to prevent connection issues with IPv6 tunneling on a couple of routers. IPv6 tunneling may lead to major connection issues resulting in heavy drop outs and glitches.

SessionLinkPRO | Recording / SessionLinkPRO | Conferencing:
You now have acces to a connection log. The connection log keeps track of connect and disconnect events and can be used to determine a session length. For increased privacy, the log is stored on the local computer only and will be deleted on log out or when the browser is closed.

SessionLinkPRO | Recording:
We’ve added an audio test loop to check the selected audio input and output devices.


On the guest side, it’s now possible to choose and test audio input and output devices before starting the session.

SLP  Major update for SessionLinkPRO | Recording

SessionLinkPRO | Recording received a major update today. The following features have been added:

  • the audio output device can now be selected directly from the user interface – no need to use the operating systems default output anymore
  • the receive meter now displays incoming stereo signals correctly
  • a “dual mono” mode was added – connect two guests simultaneously with full channel separation


To use the new features, Chrome version 49 or above is mandatory. But don’t worry: older Chrome versions will still work with basic features. More information on the brand new “dual mono” mode can be found in the revised quick start guide in the support section of our homepage.
