8x8 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

It is especially valuable in helping with communcation between remote team members. The ability to call and share screens is really helpful, and has become our go to method to communicate, eliminating the need for skype and our various conference call systems available in our company. Using Slack for calls and meetings is now extensive within our group, and is done many, many times per day. it is easy to add people and to share and give sharing capabilities to other team members.

Pros

8x8 Virtual Office

  • The control panel is great and gives us full flexibility over how our system is configured.
  • The customer support at initial setup was superb and we had a dedicated account manager who ensured that we were fully configured and working the way we wanted before handing over to the ongoing support team.
  • The smartphone app is great and is just like having your fully-functional desk phone in your pocket.

Cons

8x8 Virtual Office

  • A good VOIP experience relies on good connectivity, so it's frustrating when your mobile phone network doesn't give you a strong or fast enough signal for a seamless experience. This isn't an 8x8 issue, but 8x8 are affected by the weak links in the chain.

Slack

  • Performance can be slow at times
  • Using slack creates a reliance on it - like any social media, feeling that you may fall behind if you don't view it for a time
  • It can be easy to miss messages if they're not directly addressed to you (which many users may forget, although this is hardly a fault of slack — they do their best to balance message notification configuration with options)

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

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).

Reliability and Availability

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.

We haven't really had any issues with Slack -- so that's part of their support: Having a product that works perfectly out of the box and doesn't need additional setup/support.

Alternatives Considered

8x8 Virtual Office

We liked the flexibility of 8x8. We liked the fact that they supply VOIP services to the regulator in the UK. We liked the robustness of their network and the quality of their support. We liked the initial discounts and the low cost of entry. We liked that they are a NASDAQ listed company so are financially secure. We liked the ease of porting over our existing numbers.

Overall I think it has the best collection of features in an easy to use interface that feels familiar to most people. I believe it is the only one that allows you to be a part of multiple teams and toggle between that with a simple click, which is great for our organization.

Scalability

Based on 1 answer
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.
