    In my opinion, if you have high volumes of inbound calls with many clients, I'd avoid using JustCall. I think it is far better suited for outbound calls (i.e. sales) or for small teams. I would also recommend using JustCall for 1:1 dialing, rather than a single phone number managed by a team. Their IVR setup and tracking down what happens when a call goes through IVR can be quite difficult to figure out what actually happened.

    Slack is ideal for Scrum and agile teams that need continuous communication during sprint planning, daily stand-ups, backlog refinement, testing, and retrospectives. Slack is well-suited for maintaining team knowledge through searchable conversations and dedicated channels, where experienced team members help onboard new QA analysts.

    Pros
    SaaS Labs
    • JustCall.io has a wonderful Chrome extension that plays nice with most other apps and extensions and enables things like a power dialer and click to call functionality to be launched from anywhere, even without being logged into the platform.
    • Just Call.io has the ability to launch and sync SMS messaging from within the Pipedrive app, adding another touchpoint to the sales cycle easily.
    • The platform developers are very open to other integrations and use cases and actively solicit feedback from their user community.
    • They are also very responsive to questions and support requests.

    • Customer issues: Threads feature allows us to group a particular issue in a single thread and discuss within that thread. I can use the thread link to embed in JIRA ticket for tracking progress in JIRA (which is our details engineering tracking system).
    • Ability to add folder to Slack channel helps keep important information, documents easily accessible. e.g., we use this to keep a "ramp up" folder that can be used by any new joiner.
    • Global search is effective when I forget which group a particular message was in.

    • 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

    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
    SaaS Labs
    I think the UI/UX needs to be simplified and reorganized. It was hard to find settings, understand what they did, and then replicate those across phone numbers. They need better bulk actions, better analytics and, frankly, more stability in the system. The negative impacts to our business overall make it such that I cannot recommend JustCall

    Slack has good usability. Devs that are not familiar with the platform are able to jump into conversations and start sharing code and links within just minutes. Non developers are also able to understand the layout such as the Project Managers that are keeping the projects on track. We have not seen any tickets where employees are having trouble understanding Slack.

    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.

    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.

    It will be compared to the quality of the service and that it is accessible to medium or small companies. It is not a tool that requires greater complexities and its functionality is quite extensive. You will discover that the benefits are more than the problems that you may have.

    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.
