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 audio calling service needs to improve its quality."

"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."

"We need a feature where you can virtually raise your hand to silently let the presenter know that you have a question."

"Sometimes Skype is slow, and we cannot use other elements of our devices while using the Skype solution."

"We have found that there is a lag because it cannot integrate with the internal landline."

"I feel bored with the look and feel of the tool, so it should be changed."
