Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

All our employees love this product. No one has ever had an issue, whether it be the phone or fax. Great during the winter when employees have to work from home because of the snow. Never had an issue with the phone app. Highly recommend this product

Usability
8x8 Inc.
I'm not using it to its full capacity like a Zoom or teams Workspace. I use the service for phone calls, hate application on my cellphone and the voicemail apparatus. This we like because it gives us the feel of a large firm when we aren't.

Reliability and Availability
8x8 Inc.
As mentioned before, we have not had an outage with the phone system per say, There was an issue with the call center where we did have an outage, but it was quickly and promplty handled by 8x8 support, they got us up and going again within 24 hours. The 8x8 hard phone and softphone side of things have been rock solid, I couldn't ask for anything more seeing we are in health care and it's exactly what we were looking for. When and if there is an issue 99% of the time it's user error

Performance
8x8 Inc.
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.

Support Rating
8x8 Inc.
We are a USA based organization. Support was refreshingly quick (callback via phone or email, online live agents). Agents are knowledgeable, thorough in their explanations, and extremely patient when dealing with end-users at various levels of the ICT knowledge spectrum.

In-Person Training
8x8 Inc.
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

Implementation Rating
8x8 Inc.
The implementation of 8x8 X was rather smooth. We had training prior to getting the system. The IT company did a good job on the training. The whole system is wonderful. Saves me so much time with the faxing, as i can just let it go by itself and not have to make sure pages don't get skipped, as with a regular fax machine.

Alternatives Considered
8x8 Inc.
I prefer 8x8 Work; it has the right number of features and modes for the communication I need. I much prefer 8x8 Work meetings to zoom meetings, as it is much, much easier to transition between devices when I am on the road. 8x8 Work is also easier to manage across multiple modes of communication.

As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio SIP Server. And one server is enough to handle thousands of calls simultaneously.

Scalability

The only issue was adding licences was not via a button click but through your account admin which seems bad practice in a SaaS world as the user should be able to sign up, amend and close their account with ease

PS had all the users etc. set up by our go-live date. All hard phones were activated and when we received them, all we had to do was set them up and punch in the activation code to activate them.
