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.

• This solution is extremely stable and has been running in our environment for several years without (unscheduled) downtime.

• The Call Manager provides us very granular settings to route our calls as we want.

• 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.

• Administration web page is little bit hard to understand at the beginning specially if you are not familiar with naming convention and GU Interfaces.
• Call Detail Record interface is fine but would be desirable to include more options that fit organization needs in terms of reporting purposes.
• Self Care Portal interface could be more useful to the end user if it includes options to manage some features without administrators involving.

• 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.

The usability part of Cisco Unified Communications Manager is very much simple from a usability point of view. Day-to-day Move Add Change Delete (MACD) can be performed by the administrators very easily with simple training. From the initial deployment point of view, some of the thing can be improved to simplify the process.

CUCM is supported by most third-party vendors for related products, so it makes finding solutions to specific needs easy. Also Cisco TAC is very knowledgeable, and we have never run into a problem they have not been able to resolve. Usually they are resolved without the need to escalate tickers either.

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.

This was the first phone system we implemented that could span multiple locations. We were very satisfied once fully implemented

We have been a Cisco based shop and have looked at other cloud voice options such as MS Teams pbx, and others, but ultimately, the features, endpoints, and reliability of Cisco has been the common factor in staying with them as our voice provider. Their integrations, room systems, and hybrid design allows for us to be flexible and keep a high up time vs reliance on 100% cloud.

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.

• Communication and collaboration - Our offices are able to communicate both internally and externally due to this system.
• Down time - Struggles with CUCM has caused a lot of down time due to the instability of the system.
• High Costs - the cost of both the license and the maintenance was much higher than other systems.

• 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.
