ProCall meets ChatGPT


Artificial intelligence (AI) in everyday working life?
Modern communication can no longer ignore artificial intelligence (AI). In fact, it can be a valuable and supportive resource in everyday work. That's why you can integrate ChatGPT as a user in ProCall chat. This way, Chat GPT is always available to you as a personal assistance - no matter if you need quick information during a phone call or if you want to create a text as well as have it translated into another language! And you can generate graphics and images, e.g. for presentations.

The most important features of ProCall Enterprise
Presence management in ProCall

With ProCall Enterprise, you always have an overview of the availability of your ProCall contacts with the rotating "CAP" - even when color blind. Thanks to the integrated calendar and MS Teams synchronization, availability is 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 to a contact according to the situation!
