Considered Both Products
Slack
Chose Slack
Slack > Teams, but if a company's infrastructure is Microsoft, you have to use Teams. Slack + Zoom has been a good combo for chat + calls.
Zoom Phone
Chose Zoom Phone
Zoom Phone was much easier to manage and use than Cisco. It also allowed us to get off premises and into the cloud. We chose Zoom to move into the future of phone systems.

Zoom Phone/contact center was much easier to setup and use than TalkDesk. It was also quite a bit less …
Chose Zoom Phone
They are very comparable.
Chose Zoom Phone
We were using Google Meet prior to Zoom, it didn't have problems any, but just the overall experience of using it was not that pleasant. We switched to Zoom for better Quality in the video as well as video both. Zoom also gives a lot of options during screen share which is very …
Chose Zoom Phone
It was a much cheaper option for us in terms of purchase of the license. It was easier to also have 1 vendor since we were already using Zoom for our conference calls. Adding Zoom Phone just made sense. Our employees travel so they were not at their desks to answer calls, now …

Salesforce
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.

I think it works well for offices that have multiple locations. Being able to give each person and office their own extension makes it easier for colleagues to connect with each other, plus it's a costs savings for each of the offices

  • Having our Phone system all in onc place. Call, Text, Voicemail. with live transcript
  • Zoom Meeting AI companion - taking notes, creating action items, and summarizing the meetings then email immediately afterwards
  • Scheduler - being able to send links to team members or vendors to book a time that works best for them that is linked and synced to my calendar.

Cons
Salesforce
  • 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

  • We needed to link each of our team members' personal emails to the Zoom account so we have to filter VM notifications out of our personal accounts.
  • It'd be nice if you could set business hours through the webpage to include a lunch break so that you don't have to manually go in to edit.

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.

Almost perfect. Transformed from just being on my mobile phone. The phone has moved from a ituility to a value driving service in the business. Nobody yet has an AI to help manage the system. Come on Zoom, seems an obvious AI use case.

Usability
Salesforce
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.

Zoom Phone has a very sleek design which makes it very easy to operate and use both in the setting up of and interacting in a meeting space. That being said, certain features can seem a bit crowded while trying to screen share or display video which somewhat defeats the purpose of the application as compared to a standard conference call.

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.

Performance

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.

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.

I haven't had any sort of issues with Zoom as of yet to have to call Support. That right there makes me think it's a good product. Simple and easy to use. Nothing confusing or glitchy that would make me have to get in touch with them. Straightforward so I'm not trying to figure out a specific workflow.

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.

The main reason why we switched to Zoom Phone is because our VOIP system inexplicably went down for almost a month and no one could figure out what was wrong. Lumen was charging way more than Zoom Workplace, but could not get the system to work.
