8x8 X Series (Formerly Virtual Office)
8x8 X-2 series seems to be particularly well suited for smaller, simple phone configurations with higher packages being more well suited for larger organizations with more complicated structures. It is very beneficial in scenarios where staff are working remotely but need to keep the appearance of working in the office, and for offices that have multiple locations but need their phone structure to work as if they are one organization.

Digium Asterisk is well suited for a city government as a communications solution for internal and external use. Other options like PBX are more expensive and hard to escalate. VoIP makes it easier to use the communications infrastructure instead that already exists rather than having to wire every phone when the solution is a digital or analog phone. In my city, government offices are not in the same place, which makes it harder to communicate everything together.

Pros
8x8 X Series (Formerly Virtual Office)
- Delivering voicemail via email and the ability to save, forward/share recordings with relevant parties is helpful and improves the ease and accuracy of relaying messages to the correct person.
- The ability to setup numbers to which to auto-forward in the instance of a power outage or internet outage is essential for running a customer service business like ours.
- The ability to record calls during training periods with new employees is great to improve customer service and sales abilities.

- Call forwarding that I can trust stays on even if my phone "refreshes."
- Ability to setup various call rules and save them to use as needed.

Cons
8x8 X Series (Formerly Virtual Office)
- It is very difficult to schedule meetings in the future in the smartphone app.
- The smartphone app should add the ability to temporarily disable incoming calls on the smartphone when someone is working in their office.
- It would be nice to have better ways to configure assistants to manage the phone calls of their executives. There were limitations and the workarounds were not ideal. We did come from a Cisco Call Manager system offered much more functionality.

- Documentation is scarce, so you have to learn by trial and error.
- Not cloud-based, and there's no mobile app.
- The ability to email voicemail messages would be great.

We've had an excellent experience with 8x8 Virtual Office. We have downtime very rarely and the service provided by all reps is excellent. The little quirks that I've mentioned as cons are minor inconveniences but I prefer working like that than hosting our own PBX.

It's really easy to use. You don't have to be technical at all to figure it out, you just have to be able to read and follow directions otherwise you will not set the system up properly and you'll need to call support. The system has so many checks and balances it's near impossible to screw it up.

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.

None of the features that are available slow down the application. The reports (even the ones with hundreds of records) complete very quickly and the web interface as well as the mobile application never struggle to load or complete a task. The analytics will sometimes take some time to reflect the online status of users but it is to be expected due to connection speeds.

The support team has not been very knowledgeable in my opinion. I have called for support assistance in a couple of instances and the rep didn't know what was wrong or they did and did not relay or provide good resources or knowledge on how to utilize the system correctly.

We previously used the Allworx on-site VOIP system. Having migrated away from Allworx, we are finding the administration of 8x8 very similar, so we came from a background of VOIP administration. Using that experience, helped us transition to 8x8 very easy. Also, not being tied to internal hardware made for a better, more flexible deployment.

[Based on] my experience, we initially had to deal with Avaya PBXs, the same applies to client instrumentation (telephones, etc.). Surely we are talking about a product much more "business-like", but the management and implementation has a high cost and is not as simple as it can be (or better) with Asterisk.

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 (Formerly Virtual Office)
- 8x8 has enabled us to totally streamline our voice calls.
- We now no longer publish our mobile phone numbers as we receive direct line calls straight to the 8x8 mobile app, eliminating the need to give out additional and personal number details.
- One single, fixed price gives us all the calls we need so we can budget precisely.

- being zero cost, we saved at least 3 million on what a legacy pbx would have cost
- the savings and speed means lower cost on our service making us more competitive
- stability
