8x8 X Series (Formerly Virtual Office)

Any business that has workers in multiple locations or workers who are based out for the office for significant periods of time will really benefit from the 8x8 cloud-based system. Your direct line follows you around, but because of the Virtual Attendant, office hours and out of hours can be configured so that you only receive calls when you're "at work."

Slack

When there's a team that spans time zones and continents, Slack is the perfect tool for communication & collaboration. It houses a workplace directory, so any employee can be searched for by name. Sending a direct message to any individual in the company is as simple as finding their name, then typing a message & hitting send! Essentially, it's a hub for all communication -- individual, team, and company-wide announcements can be quickly & easily disseminated using Slack.

Pros

8x8 X Series (Formerly Virtual Office)

  • Conference call feature is great. We have created multiple conference bridges, we even have one tied to our virtual attendant.
  • We like the flexibility of the auto attendant and being able to have more than one profile saved that we can change as needed
  • Having Virtual office was especially great when hurricane Irma came through last year and our office had no power, it allowed us to continue to operate from our cell phones without the customer realizing there was anything different.

Slack

  • Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application.
  • Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side.
  • Slack continues to refine and improve their product, with new features being rolled out just about every month.
  • Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.
Benjamin Plotkin | TrustRadius Reviewer

Cons

8x8 X Series (Formerly Virtual Office)

  • Ability to integrate multiple businesses onto a single desk phone (or possibility this is a lack of familiarity with the system).
  • Have had no follow-up from the sales rep following the initial onboarding to ask if everything is alright. Would appreciate this.
  • Hardware delivery was somewhat slow, but there's this thing called coronavirus which may have impacted normal delivery times so not sure.
Jonathan Harris | TrustRadius Reviewer

Slack

  • The sorting of channels - it's a bit confusing, could be better sorted, it would make it easier to search and make it more agile.
  • Search - It could also improve, it is not bad, but in some cases (rare) it is difficult to find the term that you want.
  • Heavy performance in other operating systems - At least in Linux, Slack seems to do a little more machine performance than when it is used on a computer running Windows.

We've had an excellent experience with 8x8 Virtual Office. We have downtime very rarely and the service provided by all reps is excellent. The little quirks that I've mentioned as cons are minor inconveniences but I prefer working like that than hosting our own PBX.

We've been thoroughly impressed and hence will renew the application for sure as it's meeting and at times exceeding our exceptions in getting things done. A surely shot application that is recommended for a startup, a small company and also very large enterprise and also for multiple open source projects.
Given the points stated, it's a renew for us.

Usability

The web interface is easy to navigate and the data that I need is only ever one or two clicks away. When running reports, I don't have to deal with convoluted filters or awkward logic implementations, it just works and it works well. If I had to fault it for something, I would say that the interface is not consistent all over the place; The account manager portal and the Virtual Office portal have two completely different styles.

Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

In the time I have used 8x8 Virtual Office, the core system has been up and running almost flawlessly though we do have a slight performance degradation from time to time as is expected of cloud software. The one recurring issue for us is that the fax connection is not always functional for outbound messages. We usually have to retry three or four times to get the fax to connect reliably to the destination machine. Once connected, it's smooth sailing.

None of the features that are available slow down the application. The reports (even the ones with hundreds of records) complete very quickly and the web interface as well as the mobile application never struggle to load or complete a task. The analytics will sometimes take some time to reflect the online status of users but it is to be expected due to connection speeds.

The support was lackluster. I thought my sales rep was going to set up the phone system for me and it took several weeks of going back and forth and then being handed off to an implementation person who helped a great deal, but overall there was an impatience on both the part of sales and implementation with the number of calls that were needed to understand and set the system up. They both told me they were admonished by their management for spending too much time with me on my calls. I tried the chat feature, tutorials, and webinars, but ultimately needed a live person to help me with the final questions needed to set everything up.

I don't need to be very technical to use the Slack or to integrate tools into Slack. Adding an app (integration) is seamless and the platform walks me through the process. I can communicate with my colleagues quickly either with chat or by using the call feature to phone them. If I ever have a product question, I can quickly go to one of our product channels and search for related questions or pose a question that our experts monitor. These features have made me more effective in my day and in managing my customer base

Alternatives Considered

8x8 X Series (Formerly Virtual Office)

As far as capabilities and ease to use, they all seem about the same. If you are not technologically savvy this all can be a bit difficult to set up by yourself. Nextiva had great customer service, but the service was not cost-effective and call texting was ridiculously complicated. If I could have access to tech support via chat it would be a lot less time-consuming.

Atlassian actually ended up shutting down HipChat and partnering with Slack, but these are areas in which I think Slack outperformed HipChat:
  • Better UX
  • Ability to edit messages once they've been sent
  • More functionalities and integrations with different tools
  • Ability to share channels with other organizations
  • Better mobile app
  • Dark mode

We've had periods where our organization has grown a considerable amount and we have had no issues in scaling our communications with 8x8. The number of possible extensions that we can use is far more than we expect to go through in a very long time. The only complaint that I have is a very minor inconvenience for me where I have to download activation codes for each phone. I would prefer to have the phones automatically activated as soon as they are plugged in.

Return on Investment

8x8 X Series (Formerly Virtual Office)

  • 8x8 has cut down total monthly phone system cost by approximately 25%.
  • We can now work remotely without missing important calls and messages.
  • We can run many more reports than we could before as to who is calling and when.
  • Auto-attendant allows office personnel to not always have to answer if only basic information is needed by the caller.
William Perdue | TrustRadius Reviewer

Slack

  • I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work
  • Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool
  • We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.
