    8x8 X Series

    The 8x8 X Series allows flexibility to use the company phone system whether you are physically in the office using a handset, or are working remotely using the app on your smartphone. We are able to deploy 8x8 X Series very quickly since there is no requirement for PBX hardware or telco lines since you just need to be connected to the internet. We can easily get new users on the 8x8 phone system immediately.

    Great for conference calls internationally. Connectivity is great and it's user friendly. Great for organizations looking to communicate globally, and also for sales teams. Not the best fit for smaller organizations as there are cheaper and easier to implement solutions out there if the requirement is just for internal communication
    Aly Hajiani | TrustRadius Reviewer

    Pros

    8x8 X Series

    • We love the conference calling since many users are working from home.
    • The fact that we can reprogram it on the fly without having 8x8 do it is a big plus.
    • Being able to take the phones with us using the app on our cell phones is a bonus.
    Anonymous | TrustRadius Reviewer

    Avaya OneCloud CCaaS

    • Strengths of Avaya include the ability to answer incoming calls in a convenient format for employees.
    • The use of Avaya proves the user-friendly design and a way for employees to adjust settings in a clear and concise manner to adjust for his or her preferences.
    • Avaya also allows the employee to transfer and conference calls in an easy drag-and-drop method and is very user-friendly.
    • The functionality of Avaya allows for the virtual employee to log in, choose various auxiliaries chosen by your company to ensure schedule adherence and maintain corroboration with other applications and software programs.
    Shauna Stermer | TrustRadius Reviewer

    Cons

    8x8 X Series

    • App improvement - connectivity issues
    • Base level training - new employee handbook/training
    • Simplify steps on an overwhelming dashboard. Maybe the ability to set up quick links for functions we do often- to update VM is many, many steps.
    • Customer service when placing a ticket - we have had many issues with them not taking the time to understand our question/problem.
    Anonymous | TrustRadius Reviewer

    Avaya OneCloud CCaaS

    • Avaya could use some improvement in moving calls off the system when they have arrived at a far destination. This is a technical point and will not be often encountered by users or most technicians and really is no fault of Avaya but crossing over into local telephone systems around the world would be a great advantage.
    • The methods for interacting with some of the menus are rather involved. The system is highly complex but at this time it is mature enough to start bringing all the control features under one roof rather than through three separate interfaces.

    I am really not the decision maker on this subject but given the cost of the investment in Avaya, I do not see the company not renewing the use of Avaya. The new licensing model no longer requires expensive upgrades to stay current with new features added to the system and really helps with the cost of investment.

    Most of the easy day-to-day questions are no longer even questions due to the ease of use and simplified experience on 8x8. Changing voicemail via the desk phone or mobile app could be simplified or match the ease of using the 8x8 desktop app.

    I find Avaya easy to use but I am not a beginner. I think it is much more difficult for beginners unless the administrator has some basic programming skills. The system is getting more difficult to use but I enjoy learning and haven't found myself stumped yet.

    In the time I have used 8x8 Virtual Office, the core system has been up and running almost flawlessly though we do have a slight performance degradation from time to time as is expected of cloud software. The one recurring issue for us is that the fax connection is not always functional for outbound messages. We usually have to retry three or four times to get the fax to connect reliably to the destination machine. Once connected, it's smooth sailing.

    No problems with performance, Pages load as they should. I can't answer on the reports side as only a handful of our Admins ( call center ) currently use that side of the software. It does intergrate very well with Office for meetings and conferences. Sometimes there is a slight lag or static when users are talking, but we found this to be a cause of a users computer had not restarted in a while, Once the user restarts thier computer the problem is resolved, So this is not an issue with 8x8

    I had very good interactions with the general support staff, whether it was over the phone or using the support portal. They are very responsive and do their very best to answer my questions to my satisfaction. My experience with follow-up by our sales representative has been below expectations, especially when it came to modifying our account.

    I give it this rating because the support services of Avaya have proven to be reliable when needed. Great feedback for our queries has always been received from the support agents. 24/7 availability of support, which is very essential as our Call Center department also functions this way, therefore, the knowledge and technical support we require is always available to us.

    The person giving the training was very engaged, He also listened and answered all the questions. He created a video for our company while he was training in case we needed to reference it again in the future. The questions he could not answer were answered within 24 hours via an email to the IT support staff here so we could share the answers with the rest of the group

    Alternatives Considered

    8x8 X Series

    8x8 X Series had competitive pricing and we absorbed another environment that was already under contract. In an attempt to have a single unified ucaas we migrated to 8x8. Cisco UCM and 3CX were more involved when setting up but gave us the ability to do anything we wanted with our calls. We had more freedom and did not have forced obsolescence with our PC or wireless clients. 8x8 on the other hand was very easy to setup once we had our call routing and flow and requires us to constantly update.
    Daniel Bonilla | TrustRadius Reviewer

    Avaya OneCloud CCaaS

    There are other vendors out there, Cisco, Mitel, Shortel, etc.... We also sell Panasonic systems. Panasonic fills a gap/price point for the businesses that wants to rely on us to manage their phone system, and get their foot in the door with a phone system. The Panasonic from an administration side can be rough on a system administrator trying to do their own MAC work. Cisco and the others all have their benefits, and drawbacks. Each have their own pricing and feature models, so it is really a wash in a matter of speaking until you get into the realm of support, licensing, and integrating with 3rd party vendors.If you do need to rely on a 3rd party vendor to integrate with your AVAYA solution, if the vendor is a Dev Connect partner you know it will work. Avaya spends weeks with vendors testing and creating documentation on how to integrate a multitude of solutions with their partners. Other competitors are lacking in this department.

    At this time, we’re very happy with the pricing model that we have worked out and they have provided for us. Just be sure to do your homework, and use your comparisons to work out your cost with 8x8. They will be very straightforward with you on what they can
    adjust for you.

    Based on 6 answers
    We've had periods where our organization has grown a considerable amount and we have had no issues in scaling our communications with 8x8. The number of possible extensions that we can use is far more than we expect to go through in a very long time. The only complaint that I have is a very minor inconvenience for me where I have to download activation codes for each phone. I would prefer to have the phones automatically activated as soon as they are plugged in.

    Return on Investment

    8x8 X Series

    • 8x8 [X Series] has been a staple for our organization for years, while it has worked, it has become dated and requires a massive update.
    • The latest update took us offline for 72 hours. Despite adhering to the instructions given in the update email.
    • Mobile and desktop apps do not function properly. The "Helper Tool" does not work and is a nuisance.
    Anonymous | TrustRadius Reviewer

    Avaya OneCloud CCaaS

    • Once purchased and running, you don't need to worry about it for years.
    • Support price is following the other companies. Price is good.
    • When you need to upgrade it the cost can grow fast as most of the time you need to replace hardware.
