8x8 X Series
The 8x8 X Series allows flexibility to use the company phone system whether you are physically in the office using a handset, or are working remotely using the app on your smartphone. We are able to deploy 8x8 X Series very quickly since there is no requirement for PBX hardware or telco lines since you just need to be connected to the internet. We can easily get new users on the 8x8 phone system immediately.

I have tried a few programs over the years to record and track calls and this one is by far the best. Easy to use and more functions than I will ever use. I love the reporting options. There was one particular scenario that comes to mind where I was glad to have FluentCloud. I had a client that was really really angry, cussing, yelling, threatening suit, etc. because he had gone to an appointment almost 2 hours away and when he got there the woman told him that we forced her to schedule the appointment, that we were pushy and rude and she just wanted to get off the phone. Thankfully I found the recording and was able to prove to him that she DID schedule the appointment but she also picked the day and time, answered all of the questions and took absolutely no persuasion at all. Basically it was an easy close. The client couldn't believe it and still to this day he is my client.

Pros
8x8 X Series
- We love the conference calling since many users are working from home.
- The fact that we can reprogram it on the fly without having 8x8 do it is a big plus.
- Being able to take the phones with us using the app on our cell phones is a bonus.

- FluentCloud is excellent at customer service, their staff is always helpful and responsive. I have never had a typical service experience where first diagnosis is always the user's system. Their engineering staff is also hands on, I've been so grateful to have Brian's help in selecting the right router - he even configured it for us.
- Ease of use, the system is quite easy to use even beyond adding extensions, users, new DID phone numbers and complex routing queues. It's also easy to configure feature codes and program them so users can perform multi-step tasks with a few key punches on their dial pad. We use feature codes to allow callers to switch their caller ID to our DID numbers that are local to the area on the fly.
- Robust features: ability for whisper coaching, barge in and a dashboard to visually check the status of each user.

Cons
8x8 X Series
- App improvement - connectivity issues
- Base level training - new employee handbook/training
- Simplify steps on an overwhelming dashboard. Maybe the ability to set up quick links for functions we do often- to update VM is many, many steps.
- Customer service when placing a ticket - we have had many issues with them not taking the time to understand our question/problem.

- There are times when calls are really garbled, there was a couple months there that we couldn't listen to any of the recordings because they were not decipherable.
- They changed something recently where now when you are listening to a recording and you hit pause it takes you back to the beginning when you start again rather than just continuing where you left off. That is a pain in the butt because I have to pause quite often for interruptions.

Most of the easy day-to-day questions are no longer even questions due to the ease of use and simplified experience on 8x8. Changing voicemail via the desk phone or mobile app could be simplified or match the ease of using the 8x8 desktop app.

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.

No problems with performance, Pages load as they should. I can't answer on the reports side as only a handful of our Admins ( call center ) currently use that side of the software. It does intergrate very well with Office for meetings and conferences. Sometimes there is a slight lag or static when users are talking, but we found this to be a cause of a users computer had not restarted in a while, Once the user restarts thier computer the problem is resolved, So this is not an issue with 8x8

I had very good interactions with the general support staff, whether it was over the phone or using the support portal. They are very responsive and do their very best to answer my questions to my satisfaction. My experience with follow-up by our sales representative has been below expectations, especially when it came to modifying our account.

The person giving the training was very engaged, He also listened and answered all the questions. He created a video for our company while he was training in case we needed to reference it again in the future. The questions he could not answer were answered within 24 hours via an email to the IT support staff here so we could share the answers with the rest of the group

None that I can think of, Besides the call tree which can get complex, the problems we ran into were not a sticking point seeing the project as a whole was such a great success. One would expect more issues to arise when implementing a whole new phone infrastructure in a company this size

8x8 X Series
8x8 X Series had competitive pricing and we absorbed another environment that was already under contract. In an attempt to have a single unified ucaas we migrated to 8x8. Cisco UCM and 3CX were more involved when setting up but gave us the ability to do anything we wanted with our calls. We had more freedom and did not have forced obsolescence with our PC or wireless clients. 8x8 on the other hand was very easy to setup once we had our call routing and flow and requires us to constantly update.

I have used others besides what is listed below but FluentCloud is by far the best I have used, especially when it comes to tracking and reporting call volume and production of our calls. Being a call center that is production based on call volume having something like FluentCloud is essential.

At this time, we’re very happy with the pricing model that we have worked out and they have provided for us. Just be sure to do your homework, and use your comparisons to work out your cost with 8x8. They will be very straightforward with you on what they can
adjust for you.

Based on 6 answers
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.

8x8 X Series
- 8x8 [X Series] has been a staple for our organization for years, while it has worked, it has become dated and requires a massive update.
- The latest update took us offline for 72 hours. Despite adhering to the instructions given in the update email.
- Mobile and desktop apps do not function properly. The "Helper Tool" does not work and is a nuisance.

- FluentCloud is a good value, we have done extensive cost comparison and the feature set vs price is very favorable.
- The lack of a contract and ability to dynamically add or remove extensions as needed is great, we only pay for what we use.
