Everyone in our company uses Cisco Jabber for phone calls and internal chat. We have around 1,000 users. For features like video conferences, schedules, and presentations, we use Microsoft Teams. 

We are a Cisco shop and during the COVID pandemic, we were using Jabber to create virtual environments to communicate with students in India and China.

We use Cisco Jabber on our intranet for internal communications. It is used for chat, sharing documents, and sharing links.
