8x8 Express

For the price, having all of these features is amazing. If you have separate divisions and want to not have a ton of crossover with calls this is a great setup. It isn’t a great setup if you need only one phone since it doesn’t make sense since you won’t use most of the features.

Rakuten Viber

It's perfect for messaging and group messaging, especially when users in group are from different places, organizations... (unlike Slack where you have to be member of same organization to be in same group). The video calls are the weak point of the app, so Viber is not good for conference calls, video calls and especially for group video conference calls.

Pros

8x8 Express

  • Being able to forward calls to my cell phone when I am out of office.
  • So much functionality. So many options.
  • One set price instead of a bunch of add-on fees.

Rakuten Viber

  • It is very easy to use and is very user-friendly.
  • You can have high quality video and audio meetings with more than 1 person.
  • You can upload any type of file in Viber (video, audio, text, GIFs, PDF files).
  • It is a very well known messenger so all people have access to it.

Cons

8x8 Express

  • Setup is a pain.
  • Transferring numbers take a long time.

Rakuten Viber

  • As far as I can tell, Viber lacks the feature to block specific callers/numbers. I've never needed to do this, but I'd like to know I have the option.
  • Viber cannot be used without wifi, so it is not possible to connect with contacts who aren't also using Viber. (Unless you want to use the paid service.)
  • This isn't a major complaint, but I find the layout of Viber to be a little cluttered. Comparing it to WhatsApp, I don't find it to be quite as user-friendly, and I sometimes stumble around to find my way to a contact to call.

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.

Alternatives Considered

8x8 Express

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.

Rakuten Viber

Skype's user interface is really glitchy and doesn't provide same functionality in terms of fun elements - emojis or gifs. Slack is excellent communication tool but as well doesn't provide fun elements as Viber does(emojis, memes, gifs and more). I should also mention that quoting in Slack is not really easy and intuitive.

Return on Investment

8x8 Express

  • We are still learning all the nuances but we miss much fewer calls.
  • Transitioning calls to the appropriate person is much easier.
  • Ease of use.

Rakuten Viber

  • Communication across department is much easier and faster.
  • It is now easier to reach staff that are on an overseas business trip, even if that one is on the go (ex: in the car, at the airport).
  • Most of our customers use Viber, therefore, it is not only convenient to reach people inside the company, it is also used for external communication as well.
