The Avaya solution only adds to the collaboration of companies with unlimited meetings and no time limit. Cloud recording features not depending on local storage space. The software has high build quality and allows high quality video calls from anywhere.

The Cisco Unified Communications Manager platform would be most suited for the below scenarios.1. An organization with very restricted policies and compliance where can't move to cloud-based solutions for data security. They can install the CUCM on-premises.2. An organization that is still on a legacy phone system could adopt CUCM to save costs and have better services.

Avaya OneCloud UCaaS
- 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.

- Administration web page is little bit hard to understand at the beginning specially if you are not familiar with naming convention and GU Interfaces.
- Call Detail Record interface is fine but would be desirable to include more options that fit organization needs in terms of reporting purposes.
- Self Care Portal interface could be more useful to the end user if it includes options to manage some features without administrators involving.

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.

Although it's very easy to use, once you understand the concepts of IP telephony, as I said before, I think Cisco could have improved the management interface of the platform, adding modern technologies and the design language of the other platforms like DNA Center, etc. This interface hasn't had a substantial improvement for about 10 years

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.

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.

CUCM is supported by most third-party vendors for related products, so it makes finding solutions to specific needs easy. Also Cisco TAC is very knowledgeable, and we have never run into a problem they have not been able to resolve. Usually they are resolved without the need to escalate tickers either.

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.

We have been a Cisco based shop and have looked at other cloud voice options such as MS Teams pbx, and others, but ultimately, the features, endpoints, and reliability of Cisco has been the common factor in staying with them as our voice provider. Their integrations, room systems, and hybrid design allows for us to be flexible and keep a high up time vs reliance on 100% cloud.

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.

- Communication and collaboration - Our offices are able to communicate both internally and externally due to this system.
- Down time - Struggles with CUCM has caused a lot of down time due to the instability of the system.
- High Costs - the cost of both the license and the maintenance was much higher than other systems.
