8x8 x series is great for a small business like mine where instead of hiring someone to be on the phone all day I can take it with me and use it on the go and it saves me a lot of money. 8x8 X Series is also great to use with your personal phone using the app and helps differentiate personal incoming calls from business calls. I highly recommend this service.

As mentioned previously, it is easy to use and access since the you can chat, send voice memos or stickers in a conversation. So in overall it's very entertaining. But throughout that, the audio quality can seem to be a bit off. (Could be personal headset issue) Overall that is the only issue that is present or consistent.

  • Viber is a cross platform product. It does not matter if someone uses Android or iOS device, it will work exactly the same.
  • Also the desktop version is very good. You can switch between the desktop and mobile versions within a conversation and see updates right away.
  • It's a very international product. It has been available for very long time, which makes it very wide spread - it has a good user base.
  • You can see the status of your messages.

Cons

8x8, Inc.

  • 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.

  • When someone sends a file in Viber, the program automatically saves it in your phone memory. This means that you must delete them manually and it really annoys me, as it takes a lot of time to do that.
  • It contains enormous amounts of adds.
  • There is file sharing limit.

Usability

8x8, Inc.

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.

Reliability and Availability

8x8, Inc.

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.

Performance

8x8, Inc.

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

Support Rating

8x8, Inc.

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.

I have not frequently used the support for Viber as I have not had many problems with it on my phone. I did use support one time for problems with the computer application and used the forums to solve my problems. They were fairly easy to follow and I appreciated the online help in that format.

In-Person Training

8x8, Inc.

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

Implementation Rating

8x8, Inc.

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

Alternatives Considered

8x8, Inc.

The 8x8 UCaaS solution provides the same functionality that we were looking for that is the same as the other cloud-only phone vendors that we also looked at. However, the integration of the 8x8 UCaaS with the 8x8 CCaaS was also a big factor in why we liked 8x8 better. The pricing of 8x8 also was more favorable and their sales team was the most responsive and helpful out of all the vendors.

End-to-end encryption scrambles my messages and delivers them as a scrambled code to my friend's device, whether mobile or desktop, so that only their device can decode them into plain text. If my friend's phone is turned off or they don't have access to the internet, my message will be stored on Viber's servers (for a limited time) until their device is ready to receive it.

Because Viber can't access or read my private conversations in the first place, Viber can't sell them.

Scalability

8x8, Inc.

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.

PS had all the users etc. set up by our go-live date. All hard phones were activated and when we received them, all we had to do was set them up and punch in the activation code to activate them.

Return on Investment

8x8, Inc.

  • 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.

  • Viber saves me financially since I am now able to communicate with my international clients for free.
  • Viber helps keep my clients engaged by the fact that I can so easily share photos, which is important as a freelance photographer.
  • Viber allows me to make my messages to clients appealing in a visual way, which I have noticed helps drive actions of my clients, such as remembering to book their next session or pay for their photo order.
