Call centers where lots of calls come in per day are better suited for Cloud office. Small businesses or companies that don’t really make outgoing calls or receive a lot of incoming calls other than within the company would not really be suited for Avaya Cloud Office.

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

Cons
Avaya
  • Avaya has very strong contact center offerings and more contact with our salesperson would be helpful, so we can explore the latest offerings
  • Although it's adequate a slightly more intuitive UI would be helpful
  • More integrated reporting at the end-user level.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

Likelihood to Renew
Avaya
Things change, business requirements change so when we come to renew we may explore other options, we might go all in on Teams or look at something different - we need something that allows us to increase and importantly decrease our licence count more flexably which Avaya / Ring Central don't allow.

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

Usability
Avaya
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.

My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

Support Rating
Avaya
I have never contacted support directly. However, my rep with Enterprise Systems is excellent. Since joining Avaya, all inquiries and/or concerns have always been resolved within a reasonable amount of time. If it's a less complex issue, it is resolved in real time. I receive a response within 30 minutes or less. When he is out of the office, he always has a backup.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

Apart from Cisco Webex Calling/app no other vendor offers their own phones hardware, gateways. We need to add other vendors like yealink, Poly, Audiocodes to complete the solution. This makes things very difficult from management perspective. As you have to hire a person who can manage a multivendor environment. Also, in case of outage, multiple bridge open and every vendor blame others. Cisco is costly so we gave a chance to Avaya UCaaS based on its history and reputation in Calling market.

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

Return on Investment
Avaya
  • This made working from home possible, allowing me to take calls that I wouldn't be able to without having them forwarded by our communications department
  • It works with Teams, realizing when I'm on a conf call and automatically sets a status of away, preventing my phone from ringing, but allowing me to see the voicemail via text so that I can respond
  • If I step out of the office for a little bit, I can have my calls go directly to my cellphone to make sure I'm still available if needed
