We have used 3rd party companies who have set up Unify for our customer sites and often it goes well. From a network perspective we often don't need to get involved too much and the set ups are often straight forward. This prevents us having to allocate engineers to new implementations.

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.

Usability
Atos
Clients seem to understand new feature sets early on and we don't have to allocate too much time to training. This creates a low learning curve across the board which can be essential when implementing new communication methods. The call quality and application support is generally very good and we don't have many calls logged for issues.

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.

As we predominantly have a cisco environment we have used Cisco VOIP solutions in the past, which obviously integrate very well, however Unify does an excellent job at integrating into our networks with out problems and doesn't require too much manual configuring or changes.

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.

  • 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.
