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.

[Google Voice is] great if you have a workforce that needs to make calls for business purposes from their personal mobile device, while keeping their personal phone number private. If you have a large company with its own telecom system, it probably won't be necessary if employees already have their own landlines or separate work phones.

- 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.

- Google Voice has been great for setting up additional phone lines and numbers.
- The voicemail inbox is a great feature and you can see when messages come in online and listen to the messages from your computer.
- Google Voice allows us to have multiple phone numbers and lines for specific business purposes.

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.

- I think there is room to improve with regards to call forwarding.
- I wish there were a concise way to know if the call was to your Google Voice number or your personal number before answering the call.
- when I add a contact to my account on the web it doesn't seem to sync with my phone even though the same email address is logged in.

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

It's user friendly, how to use it is self explanatory, they support all their own options while someone like Phone Booth uses a third party. I can cancel Google Voice anytime and I choose how much I spend with Google Voice

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 haven't had problems with dropped calls, bad reception, lost recordings - everything works the way it should. The iOS app is easy to use, and the process is easy to explain to other people. It's also the cheapest way I've found to call internationally - I've used it to interview people from London and Austraila.

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.

They do not offer support unless you have the Business account for Google Voice under G Suite. This is tough, because Google doesn't really have a customer support team for this service, so when it gets shut down for a few hours, we have no choice but to wait it out. But this doesn't happen that often, which is great.

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 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.

The integrations of Google Voice with all our devices are flawless, Android, iOS, Windows, Linux and Mac. Also, the call performance is far superior on wifi as well as on mobile data. With Skype, we had several problems with personal accounts, performance issues, and in general, it felt awkward to use it.

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.

Google Voice should be also be use to those who have difficulty in speaking English.So the contract term will need to be a little strict as Google Voice is used in navigations as the part of GPRS navigation is personal.The private data need to be in control much more securely and safely.

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] 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.

- Cost for Google Voice is stellar, starting at $10/mo per user.
- While it doesn't offer a new Audio/Video conferencing solution it does integrate with GSuite so it makes use of Google Calendar and Hangouts/ Google Meet.
- Gets the employee's to use their company phone numbers more as texting is easy and deployment is simple.
- The cell phone app is reliable and easy to deploy.
