The most important functions of ProCall Enterprise
Presence Management


With ProCall Enterprise, you always have an overview of the availability of your ProCall contacts with the rotating "CAP" - even with poor color vision. Thanks to the integrated calendar and MS Teams synchronization, availabilities are set automatically. However, current status messages, such as breaks, can also be set directly in ProCall itself. This way you can always choose the most appropriate communication channel for a contact depending on the situation!
