Video meetings and presentation sharing impress but user-friendliness and pricing need attention

I don't have experience with how Avaya Spaces handles integration with other software tools, but perhaps my partners have experience regarding integration with different vendors. If Avaya can integrate Spaces with other media solutions, such as WhatsApp or WeChat, it will be more friendly and useful for customers or partners.

Relying on dependable communication features for efficient collaboration

I work with Microsoft Exchange. We use Microsoft Azure, though I am not involved with the back-end operations. I work with Microsoft Exchange and ServiceNow for the service desk. I do not work with Cloud Observability or Automation Engine. We use Microsoft Copilot with Teams. We do not use Microsoft Security Copilot as it is not cloud-based. We have moved from Skype for Business to Teams recently, though some of us still use Skype for Business because it is convenient. Skype for Business is particularly useful for remoting onto people's devices. I prefer Skype for Business over Teams for screen sharing. Sometimes there are compatibility issues when running Microsoft Teams and Skype for Business together. Phone calls in Teams might ring and then go silent, or the microphone might not detect calls from either application. I rate Skype for Business a 9 out of 10 because it works effectively with minimal issues.

Cons

"The initial setup for Avaya Spaces is very good for me, but for sharing with other users, the setup is a little bit complex compared to other solutions I have used, such as Zoom or Teams, as the installation is more complex."

"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."

"The audio calling service needs to improve its quality."

"The solution isn't connected to Microsoft Teams, and I feel like there is better communication on that particular solution. The group capabilities are a bit less than Teams."

"The video conferencing quality can be improved."

"I feel that the whole look and feel of Skype should be improved, including its user-friendliness. It should also improve its scalability."

"There are issues with the bandwidth, particularly for external meetings,"

"The solution's functionality needs to be moved to Microsoft Teams. Its technology is outdated."

"The solution lacks to provide reporting functionality, and I would like to see the solution provide that feature."

"Skype for Business could improve by having a document channel or repository. Microsoft Teams has a better repository place for documents that you can share with your team. You can access it anywhere from any device."

"There are some issues with stability during phone calls. Sometimes the connectivity drops, and it is frustrating."
