Pros / Cons
- Overall, my experience with Avaya UCaaS has been good, it delivers dependable communication and collaboration, though the interface and features could use some modernization.
- Some of the features feel a bit outdated and slow, and the interface could be more modern and user-friendly.

- It allows us to create custom dashboards, reports, and visualizations to help our teams better understand their performance and data.
- Calabrio does not do that so I have to set an alarm on my phone and when it goes off it interrupts my calls because I'm not going to change the volume from my morning alarms.
