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.

MiCollab is great for a large office to get users working from home and being able to use their home phone or cell phone like the desk phone at the office. This allows our live operators the ability to see if the end-user is on an active call before sending a new call to them. If you have a very small company of fewer than 10 people this might not be worth the investment as cell phones would work just as well.

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.

- Mitel MiCollab is great for working remotely. The twinning feature to allow calls directed to my office phone to ring on my cell phone is extremely convenient.
- The feature that allows you to set which device you want to ring (desk phone, PC, cell phone) is great as even when I am in the office, I prefer to just use my cell phone.
- The customer support for the product is first-rate. They are always present and helpful when needed.

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.

- Easy to use pop-up window alerts you to incoming calls, lets you transfer to VM or other users, helpful for conference calling
- Has chat feature to tag someone when they are on the phone, or you just don't want to call
- App for smartphone allows for desk phone to cell phone collaboration

Everyone at the company now have the experiance needed to make phone calls, meetings, video conferencing. It's easy to use is unmatched in the industry. It's been a solid product throughout. The phone tree was easy to setup with the implementation team and they guided us throughout the process

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.

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.

Support is typically handled by a reseller. Buyers should evaluate the reseller as much as they evaluate Mitel for the product suite.The few times when the reseller was not able to handle the issue directly, Mitel did step up and quickly answer/address the question/issue.

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

None that I can think of, Besides the call tree which can get complex, the problems we ran into were not a sticking point seeing the project as a whole was such a great success. One would expect more issues to arise when implementing a whole new phone infrastructure in a company this size

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.

MiCollab was great as a VOIP solution and general team collaboration solution, but it lacked in some areas, such as the mobile app, complex configuration and set up as well as the lack of user customization. Overall, the system is serviceable, but seemed rather vanilla compared to its competitors

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.

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.

- I'm not a person in a position to really speak to this question as I'm only a user and not involved in purchasing such services. Overall, though, I believe we switched to this to save money and since we seem to be sticking with it, I have to assume that objective has been achieved.
