Fuze

I think you need to be in a user base of at least 50 or so to reap the benefits. A small company with one location and no remote users may not need the flexibility and feature-rich Fuze environment.

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

Fuze

  • The Fuze implementation process was the smoothest and best-organized roll-out of any major infrastructure project I have been involved with. The engineering and sales team provided a clear roadmap, stuck to it, and performed flawlessly.
  • The system stability, voice quality, user provisioning and de-provisioning, and overall ease of use is something Fuze has done particularly well. Whatever I need is there in the portal, and the 'take-it-for-granted' feeling the users have is a huge strength.
  • Continuous improvement- in the two years this company has used Fuze we have seen numerous updates to the softphone, new features in the desktop phones, and constant communication from our customer advocates and support team.
  • Tech support- rarely used but responsive and experienced, a definite strength.

Slack

  • Easy to use. Nice UI and UX.
  • Get a notification for every message that we receive.
  • Can form a small group to communicate with others while working on a common project.

Cons

Fuze

  • A more aggressive end-user training and help scenario. Users who are unfamiliar with UCaaS and are wedded to the traditional role of the desktop phone can be slow picking up the idea of a UCaaS account and all the benefits and possibilities. More visible links and reminders on the phones, softphones, and apps, and easy access to short videos put right in front of users' eyes might help user adoption.

Slack

  • Slack has very little room for evolvement, it has almost done everything perfectly.
  • It has an initial learning curve since it is different from other messaging apps.
  • It can be a little resource intensive but given the features, it is hardly surprising.

Most of users are now familiar with Fuze and have been using it over a year. Technical Support from Fuze has improved since we originally implemented and now have a customer success/experience rep that we have bi-weekly meetings with if any issues need to be addressed.

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

Fuze

Fuze 9.1
Based on 1 answer
Because the people who designed Fuze were Data-center people, they thought of availability first, there really isn't any excuse for telephony downtime, and they certainly do well with this. There has never been a total outage, just a few features sometimes have been offline while Fuze moves the service to other servers, NEVER calling, sometimes chat or physical phones (which can be fixed by rebooting them). The uptime on the Fuze systems is basically: Always up, always available.

Performance

Fuze

Fuze 9.1
Based on 1 answer
Since Fuze runs across multiple devices and platforms they really strived to make a lightweight interface that is optimized for phone calls, chat, and collaboration. The web client loads fast, the chat is always up-to-date, phone calls arrive on-time. The desktop client is the most feature rich and basically it just adds desktop sharing functionality as well as VoIP for calling, and the mobile client doesn't consume a lot of battery, and it stays running to get phone calls, chats, and can do meetings over Wifi, Cellular Data, or Cellular voice.

Support

Fuze

Fuze 6.6
Based on 59 answers
I have used both online and telephone support and have been completely satisfied. The overwhelming majority of our support requests have been user provisioning and de-provisioning, and with the introduction of the Fuze Hub recently I'm in a self-service mode. The only real tech support was right after go-live getting our firewall rules perfect. We have had no support calls for dropped calls or poor quality in two years. Support has been great, just haven't needed much of it.

Fuze 9.1
Based on 1 answer
At many of our sites with more than 50 users, Fuze sent someone onsite to train. This worked surprisingly well, as the trainer allowed the users to set the pace and answered TONS of questions. Fuze has a very streamlined training process, their staff is very professional, very knowledgeable and very engaging.

Fuze has vast amounts of training videos and guides on how to use its products and services. There are literally endless-hours of training and I often point end-users to a particular video which addresses the specific needs of the user, for example: how to check voicemail. Or, how to share your desktop, etc.

They dedicate a project team to implementations and are very effective at getting the job done on time and on budget. They manage the cutover process with the utility companies and losing carrier and make it as pain-free as possible

Alternatives Considered

Fuze

Overall, Fuze is better organized, easier to navigate and faster to get up and running that GoToMeeting was. I strongly prefer Fuze from both an end user and also administrators perspective

Slack

When it comes to the extensibility and the third-party integration features of slack, there are few competitors. Slack is leading the collaboration space and has created a revolution. With the precedent it is setting, it is merely a matter of time before people start moving en masse from more traditional enterprise team collaboration tools to collaboration software like Slack.

Scalability

Fuze

Fuze 9.1
Based on 1 answer
Fuze does have scalability limits but most of that is how many end-points they can put on a virtual PBX, or VCX as they call them, I THINK its limit is somewhere between 2,000 and 5,000, but we've not had issues with that because we have put users into various VCXs some by location, some by department or function. Either way, we have 7,000 currently deployed, and are going to end up with over 15,000 when we are done, Fuze is VERY scalable.

Return on Investment

Fuze

  • Positive ROI within 6 months
Travis McKeone profile photo

Slack

  • Save time due to the notification tool which lets me know when someone is updating something
  • Save time on catching up on specific tasks because of the organization in channels
  • The negative impact I have experienced is when I try to search files that were shared some time ago and I could not find them
