Likelihood to Recommend

Fuze

Fuze is very good around collaboration, meetings are simple to set up once initial familiarity is done. The telephony is consistently of a high quality and very reliable which keeps the users happy. The chat functionality is improving and becoming more useful and being picked up as a tool by a growing number of users. Fuze lacks the flexibility of being able to compete with WebEx regarding remote control of a computer for someone who does not have Fuze installed. This is required by customer support personnel dealing with customers who need to have an issue resolved but cannot install software without change control.

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.

Cons

Fuze

  • There is lack of customization. I would love to have access to set up background colors for my Fuze, add wallpapers as a background. Change the font, color of numbers and texts that appear on the screen.
  • I have seen a button saying you have an upgrade on Fuze. And i see it quite a few times. I would want to have like one upgrade that pushes a couple of updates together rather than couple of small upgrades.

  • It's a minor point and one that's likely outside of Slack's core competencies, but if you're looking for a communication tool that also includes voice chat, this isn't it.

Likelihood to Renew

Fuze

Fuze 7.4
Based on 14 answers
1,000% will renew. For the price, for the features, for the support, for the implementation, for the ability to deploy to a new site, or a new company acquisitioned that has an older PBX, we can get them to Fuze with so little effort, dump the phones on their desk, and give them all the features and "WOW" that they would expect from a modern enterprise.

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

Usability

Fuze

Fuze 7.7
Based on 7 answers
Fuze was built with the end-user in mind. It was built to have a common interface on mobile and desktop. Fuze Web is new, and it also has the exact same interface as the desktop and mobile, and they are still working on the ability to make phone calls from the browser itself, currently it can do meetings just fine. Everything about Fuze was built with the end-user in mind.

It's an amazing communication tool. It's like Slack took everything that made Skype amazing at the time, made it much lighter and tailored it to make it work in a business setting. I love that, even though Slack isn't a project management tool, it can help you manage and not stress the day-to-day stuff.

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 65 answers
In the case of support, they have come a long way I'd say. The support wasn't the best at first. It was fairly average. But they have improved a lot over time that we've been using Fuze. I think as the company has grown in size and customer base, so has the support, which is opposite to other companies whose support degrades when they grow. But Fuze has consistently improved support.

I haven't ever had to contact Slack's Support Team, but outages are rare and the app loading and syncing speed are as good as any app I have used.

In-Person Training

Fuze

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.

Online Training

Fuze

Fuze 9.1
Based on 1 answer
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.

Implementation

Fuze

Fuze 7.6
Based on 64 answers
The implementation of Fuze is fairly straightforward, they have 3 options, get new numbers, keep your number and migrate on your port date, or forward your existing numbers to RCF numbers that are just temporary until you are ready to port all your numbers to Fuze. We've used all 3 methods across various sites of ours.

Alternatives Considered

Fuze

At the time we were looking, Fuze was the only UCaaS provider with enough global presence to get the Holland office a local number within the Fuze system, making it easy for us to manage both locations in one place. The pricing and features from Fuze, and the ability to consolidate voice, video, and text between our two offices under one platform drove the decision.

Slack

We used to use a combo of Google Hangouts, email, and the GroupMe app for all internal communications. Slack has completely eliminated those and we use Slack for all internal communication—we don't even use email for the most part unless communicating with a client. If you work with tech savvy people, Slack also has slackbot which allows you to integrate with almost anything (JIRA, HubSpot, etc.) and save a ton of time through automation of tasks.

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.
