    Chose Google Voice
    Google Voice is great if you are a one-man business. It allows you to have a business phone number for people to call without having to give your personal cell phone number out to strangers. The cost is very affordable. But as your business grows, you need to look for a better …

    Google Voice and Dialpad, I believe, are a very equal match, and we chose Google Voice due to only a small amount of interface differences that made a difference in the service's functionality. Also, we had used google voice for a long time before Dialpad, so making the …

    I do think Google Voice works well for organizations that do not have a support team meant to provide regular telephone support, and instead do so on an ad hoc basis. I would not recommend it for high-volume call activities, such as SDR motions.

    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
    Google
    • Google Voice has been great for setting up additional phone lines and numbers.
    • The voicemail inbox is a great feature and you can see when messages come in online and listen to the messages from your computer.
    • Google Voice allows us to have multiple phone numbers and lines for specific business purposes.

    • 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.

    Cons
    Google
    • There has not been much innovation since the initial release.
    • It doesn't handle SMS well.
    • It does not natively integrate with CRM without legacy complication
    • It is not supported by Google as it once was
    • Call Recording is non-existent
    • Call-Tree or Virtual Auto-Attendant needs are not available

    • 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

    Google Voice has been invaluable for us in our effort to provide exceptional customer service. With Google Voice, we have been able to increase our customer interactions while reducing the wait time to reach a live person on our team. We couldn't be more pleased with the way things have worked out since implementing Google Voice.

    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.

    I think it works really well in the arena it operates in, but not so well in areas where an enterprise system would be more appropriate. It's great for quick solutions that just work, but not so much for more complex call management tasks.

    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.

    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.

    They do not offer support unless you have the Business account for Google Voice under G Suite. This is tough, because Google doesn't really have a customer support team for this service, so when it gets shut down for a few hours, we have no choice but to wait it out. But this doesn't happen that often, which is great.

    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.

    The integrations of Google Voice with all our devices are flawless, Android, iOS, Windows, Linux and Mac. Also, the call performance is far superior on wifi as well as on mobile data. With Skype, we had several problems with personal accounts, performance issues, and in general, it felt awkward to use it.

    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.

    Google Voice should be also be use to those who have difficulty in speaking English. So the contract term will need to be a little strict as Google Voice is used in navigations as the part of GPRS navigation is personal. The private data need to be in control much more securely and safely.
