Atos Unify OpenScape Voice vs. Rakuten Viber

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.

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.

• Good integration with other system
• Smart features and web applications
• Good cloud and non-cloud options

• 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.

Incentivized

• Phone application could be improved
• Troubleshooting can be difficult
• Can rely on a solid network and internet connection

• 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.

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.

Rakuten Viber is overall the best. Hands down!!! Even though the other products have their own use and they are well functioning in the market, but Rakuten Viber is still top notch!

Incentivized

• Ease of use gives clients peace of mind
• Easily customisable
• Administratively very convenient

• Rakuten Viber allows me to delete any type of message I've sent
• Rakuten Viber can't access or read my private conversations in the first place, Viber can't sell them.
• Hidden Chats allows me to keep whatever chats I want away from my main chat list, so they don't show up in my main chat list. Only a PIN that I set gives me access to Hidden Chats.
