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.

JustCall.Io is well suited as a backbone phone system with many capabilities for small to medium-sized businesses and their sales teams. With its rich feature set, dependable functionality, and developer and integration-friendly architecture, it could be a great solution.The platform is less well suited for those companies that have a well established telephony solution and are only looking to take advantage of one or two of its features, such as SMS for instance. There are probably other solutions that provide the same functionality at a lower price point.

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.

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.

- Customer service/ease of contacting could be better for worldwide users (I believe they're sourced overseas)
- Pricing seems to have increased, which affected the benefit we originally found in the service
- Increased functionality, such as bulk SMS Messaging and power-dialer

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.

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.

It will be compared to the quality of the service and that it is accessible to medium or small companies. It is not a tool that requires greater complexities and its functionality is quite extensive. You will discover that the benefits are more than the problems that you may have.

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.

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.

- Overall, JustCall showed us the value of having an integrated tool to allow the execution of SMS messaging from within Pipedrive. It definitely allowed us to add in additional touchpoint that some decision makers and prospects felt more comfortable using.
- Despite the tight integration with Pipedrive, the totality of the solution added more overhead in financial and configuration/personnel terms than we were looking for. Since we had established a great set up for our phone systems already, adding another one just to access SMS didn't make sense.
- SMS from inside Pipedrive was the only function we were looking for. Just Call does this, and does it really well. But since we had our phones and VOIP already providing this outside of Pipedrive, it was ultimately not suitable. It became an expense for which there was not really a clear justification for in terms of ROI.
