    For the daily faxing needs, eFax gets the job done. We get notified when the fax has been received or sent successfully, but it takes so long at times. I'm not sure if it's eFax's encryption system that is delaying the Rx/Tx time, but it needs to be improved immediately.

    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.

    Cons
    Consensus Cloud Solutions
    • The user interface could use some work, as it's a little dated looking, and it's not so simple to receive faxes, at times.
    • Administrator functions. If the user's account is locked for any reason, the administrator cannot unlock their account. It causes a lot of inconveniences.
    • Unable to see the bill. For whatever reason, eFax does not allow viewing the bill from the online portal.

    • 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.

    For our logistics side of the business, we use eFax to receive orders. We are using it to transmit a variety of documents as well. It comes in handy if you really need to accept faxes.

    eFax support is great. They are quick to assist you with any issue regarding eFax. I haven't had to wait long on support services or answers. During an outage seems to be when the queue times get long but on a normal day, they are quick to answer and fast on a solution.

    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.

    eFax is for serious business professionals and it comes with so many tools, including a free App and a desktop app, which makes it extremely easy for you and your employees to send and receive faxes. You can take a photo of a document and fax it over to someone in another state in a few minutes!

    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.
