SLP  New versions online

Maybe you already have noticed: new versions of our products are online since 03/17/2019. Here is an overview of the changes:

SessionLinkPRO | Recording:

  • By popular request, we have added a new routing option to the “dual mono” mode. If activated, “bridged” allows the two guests to communicate with each other. Full signal separation at the host is preserved for recording both guests on dedicated channels.

  • The “Record” feature now allows to record both, local and remote signals, at once. Of course with full signal separation.

SessionLinkPRO | Conferencing:

  • Again, a popular user request turned into a new feature: we have added a group chat.

  • The SIP client now comes with an additional dial pad. For example, it comes handy if you need to enter a pin code for a phone conference.

SessionLinkPRO | Conferencing + SessionLinkPRO | Video:
We have added Firefox support for SessionLinkPRO | Conferencing and SessionLinkPRO | Video. Please note: this feature is in beta test, so no guarantee!

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  Release: SessionLinkPRO | Conferencing

We are happy to announce the commercial release of SessionLinkPRO | Conferencing. The beta test phase will end on 1st of May 2017, after an extensive testing period. Regular SessionLinkPRO | Conferencing subscriptions will then be available through our online subscription system.

SLP  Major update for SessionLinkPRO | Recording

  • the audio output device can now be selected directly from the user interface – no need to use the operating systems default output anymore
