New in ProCall Enterprise 7.4: Enable and use ProCall Meetings integration for ProCall client for Windows

PROCALL ENTERPRISE  PROCALL MEETINGS  INTEGRATION REQUIREMENTS  USER MANUAL ADMINISTRATION CONFIGURATION

The  ProCall Meetings Integration has been significantly enhanced with Version 7.4 of ProCall 7 Enterprise. More options are now available for the ProCall client for Windows with version 7.4.

By integrating ProCall Meetings into the ProCall client for Windows, you can now use ProCall Meetings functions such as starting, scheduling and inviting participants directly in the ProCall client for Windows without having to switch to the ProCall Meetings platform. The integration makes the appropriate menu items available to you simply by clicking on them in the context menu or action bars, for example in the "My" area, in the chat window, in the call window, in the monitor or in the favorites for the respective contact. Invitations to meetings and links to a meeting can be easily sent via chat or e-mail. In addition to your other upcoming appointments, you will then also be notified of upcoming online meetings via the speech bubble and can participate directly with a simple click.

The integration can be administratively made available to all ProCall Enterprise users who have a license for ProCall Meetings activated.

We have compiled for you which requirements you have to consider, how to proceed with administration/configuration and which functions you can use in which context menu in the ProCall Enterprise client for Windows with the new integration in a new article.

New in ProCall 7 Enterprise SR4: Support for new Busylight models

PROCALL ENTERPRISE   INTEROPERABILITY BUSYLIGHT  KUANDO PLENOM 

The ProCall client for Windows supports two new kuando Busylight models by Plenom:

  • Busylight Alpha Model 2
  • Busylight Omega Model 2

The Busylight is connected to a USB port of the computer. It signals the presence status of the ProCall user via an LED light. This makes it easier for those present in the office or working from home to recognize whether the respective ProCall user is available/reachable (green) or not, e.g. if they are on a telephone call (red). 

We have added to our overview of supported third-party products for the new models:

Performance monitoring for ProCall Enterprise

PROCALL ENTERPRISE  PROCALL MEETINGS  INTEGRATION REQUIREMENTS  USER MANUAL ADMINISTRATION CONFIGURATION

If necessary, it may be necessary to monitor the operation of the estos ProCall Enterprise server with regard to a wide variety of features on the Microsoft Windows operating system and also to collect the recorded performance indicators over a longer period of time.

The performance monitoring included in the Microsoft Windows operating system, also known as Windows Performance Monitor, is suitable for this purpose.

To avoid having to search for and individually compile the multitude of possible performance indicators, a template for the data collector set is available in the form of an XML file that can be easily imported so that the data collectors and their indicators can subsequently be adapted to the respective needs of the environment to be monitored.
