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.

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.

- The menu options in the interactive voice response function are very efficient and necessary for the fluidity of communication with customers. The best thing is that the customer can access this menu from their phone.
- We love that it is a multi-channel platform, that allows us to be aware of the demands of our customers on all digital platforms.
- It allows us to make recordings of incoming and outgoing calls to get more details of our customer's needs.

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.

- Inbound call functionally is still limited and not something that my team utilizes.
- The reporting features for the some of the lower pricing tiers are very limited.
- Downloading reports from the cloud can be quite slow at times.

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.

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.

Return on Investment
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.

- Our sales team is making more calls and the calls have improved in quality....this is leading to more customer interactions.
- Our customer service has improved with the call recording. We are able to go back and listen to issues and customize our responses based on the recordings.
- Managers are better able to identify sales members who are consistently meeting their call targets. This has improved our goal-setting and reward system.
