For the price, having all of these features is amazing. If you have separate divisions and want to not have a ton of crossover with calls this is a great setup. It isn’t a great setup if you need only one phone since it doesn’t make sense since you won’t use most of the features.

- I would like to see more of their in office communications systems. Right now they seem outpaced by competitors even though their core services are superior.
- The interface could be updated a little. There is a lot of interaction that the operator needs to go through that could be automated.

There are few times that we have not been able to take advantage of the tool, but those moments are related to the bandwidth of each person in [their] home. Those who have low signal cannot access meetings on the platform smoothly.

We have never had problems with Avaya Spaces instabilities or inoperability. I believe the Avaya server is Tier3 with 99.9% availability. The meeting rooms are always active and can be accessed from anywhere and from any device because it has an official app on Android and iOS. I do not recommend going through the browser in meeting rooms because the experience is not so positive.

The software is really great, the only problem being the integration with email platforms like Outlook. It is necessary to create a plugin to optimize the invitation experience. But I have nothing to complain about the rest. It's perfect, the experience during the meetings and the audio and image quality are differentiated and with excellent quality. Avaya Spaces works great on PC, web and apps and gives us a lot of mobility.

If you get less than 4 phones you fall into the online only customer service. There were a couple of times that I could have used more assistance but figuring it out online was a bit of a hassle.

The support is good. Avaya is one of the largest companies in this area of ​​unified communications. Support can be activated by phone and email. Our team has already triggered a few times and from what they told me everything was normal and fast. The price is a little expensive but I believe it is worth buying together for more security.

I love 8x8. Having not used Polycom phones before, the hardest part was learning how to set up and use the actual phones. 8x8 makes it a seamless transition from using other service providers. Their customer service is excellent although if you get their cheapest plan you will only get online assistance.

I have experienced less technical problems with Avaya compared to other platforms. Avaya was easy to implement for all ages as it didn't require a lot to log into sessions for the younger grade students and the features are simple enough that my first graders can use Avaya without the help of their parents.

The intermediate version prices are cheaper than the leading video conferencing tools, but it does not have the recording feature. If I could change one thing, I would put this cloud recording functionality in this intermediate version of Avaya Spaces as well. I believe it would be a big differentiator from the competition.

One of the features of the PRO version, known as Power, is the possibility to record unlimited meetings in the Avaya cloud without worrying about storage space. We keep it for 30 days and then an intern downloads it to our internal network. This version also allowed us to do some events with more than 100 people connected without causing any network instability.
