The Avaya solution only adds to the collaboration of companies with unlimited meetings and no time limit. Cloud recording features not depending on local storage space. The software has high build quality and allows high quality video calls from anywhere.

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.

Avaya OneCloud UCaaS
- I would like to see more of their in office communications systems. Right now they seem outpaced by competitors even though their core services are superior.
- The interface could be updated a little. There is a lot of interaction that the operator needs to go through that could be automated.

eFax
- 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.

There are few times that we have not been able to take advantage of the tool, but those moments are related to the bandwidth of each person in [their] home. Those who have low signal cannot access meetings on the platform smoothly.

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.

We have never had problems with Avaya Spaces instabilities or inoperability. I believe the Avaya server is Tier3 with 99.9% availability. The meeting rooms are always active and can be accessed from anywhere and from any device because it has an official app on Android and iOS. I do not recommend going through the browser in meeting rooms because the experience is not so positive.

The software is really great, the only problem being the integration with email platforms like Outlook. It is necessary to create a plugin to optimize the invitation experience. But I have nothing to complain about the rest. It's perfect, the experience during the meetings and the audio and image quality are differentiated and with excellent quality. Avaya Spaces works great on PC, web and apps and gives us a lot of mobility.

The support is good. Avaya is one of the largest companies in this area of ​​unified communications. Support can be activated by phone and email. Our team has already triggered a few times and from what they told me everything was normal and fast. The price is a little expensive but I believe it is worth buying together for more security.

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 experienced less technical problems with Avaya compared to other platforms. Avaya was easy to implement for all ages as it didn't require a lot to log into sessions for the younger grade students and the features are simple enough that my first graders can use Avaya without the help of their parents.

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!

The intermediate version prices are cheaper than the leading video conferencing tools, but it does not have the recording feature. If I could change one thing, I would put this cloud recording functionality in this intermediate version of Avaya Spaces as well. I believe it would be a big differentiator from the competition.

One of the features of the PRO version, known as Power, is the possibility to record unlimited meetings in the Avaya cloud without worrying about storage space. We keep it for 30 days and then an intern downloads it to our internal network. This version also allowed us to do some events with more than 100 people connected without causing any network instability.
