8x8, Inc.

Business telephone/voicemail services. This has enabled us to no longer need a receptionist, the system handles it all for us. We have been able to route callers easily to the party they need to speak with. This includes virtual mailboxes and auto forwarding which were very useful during the pandemic. Working remotely was seamless with the help of 8x8 Express. We were able to forward calls to our cell phones easily. We can write out a greeting message and they will record it and it sounds great. It's easy to update on an as-needed basis.

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.

  • 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.

    If you get less than 4 phones you fall into the online only customer service. There were a couple of times that I could have used more assistance but figuring it out online was a bit of a hassle.

    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.

    I love 8x8. Having not used Polycom phones before, the hardest part was learning how to set up and use the actual phones. 8x8 makes it a seamless transition from using other service providers. Their customer service is excellent although if you get their cheapest plan you will only get online assistance.

    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.

    Return on Investment

    8x8, Inc.

    • Positive impact - pricing is right, service is easy to use.
    • Especially during the pandemic, clients who would normally just pop by the office had to call in. 8x8 Express made that so easy as we could transfer calls to our cell phones, but also received emails when a voicemail was left with an audio recording of the message. We didn't miss a beat!
    • We use some contractors that are not even in the same state as us, but our clients wouldn't know it as autoforwarding calls is super simple and seamless

    • 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.
