Had I completed this review a couple years ago, I would have given a rating of 9 or 10 as Hangouts (Classic) is an excellent product. However, now that Google Chat has succeeded Hangouts, I would not recommend that any new users begin using it where other more modern options are available. Android users who want an internet based instant messaging that also supports calling and video calling could benefit from using Hangouts (Classic) as Google Chat requires the user to also have Google Meet installed to make video calls and there is no voice only calling option.

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.

Cons
Discontinued Products
  • I would like to see improved video support, so that saved videos can be sent back and forth via Hangouts more easily, without having to start a separate meet chat
  • More pronounced notifications of messages would be helpful; pop up notifications are good, but once there is one, additional messages do not pop up
  • Custom muting times would be great, so that if I am in a 90 minute Zoom meeting, I can set it for that time; right now, it is 1 hour or 2 hours. Easy to forget.

The tool is almost self-implemented. It is likely to be available in every pc or mobile device a user or potential user might have, and all you need to do is adding the company's account and you are done. Once you are setted up, you have almost all actual communication methods available in one tool

Google Hangouts works great and does not require a lot of work to troubleshoot. Everything is simple and easy to use. Google provides all of the tools that one requires to utilize Google Hangouts and any information can be found in the built-in help tools. There is also a forum for users to report issues and typically, Google responds well and will try to work out any issues.

Google is the white cotton socks of the conferencing world. It’s a great ad-hoc tool, but not too much more. If you are not looking to spend money or operate completely on WiFi (without data charges), it’s a great free option as well. The benefit of being free and open is also the liability. It doesn’t have a great integration story with other corporate tools, but [it doesn’t have to] if you aren’t looking for that. All in all, it’s as helpful and ubiquitous as a public payphone…without the pay…and with a video capability.

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.

  • I believe it was part of the google suite that was purchased. It was worth the cost as it was cheaper. I believe it is now free, but also becoming deprecated. It is much better to use Teams, Discord, Telegram, etc. Google does not provide enough support or features to make using hangouts worth it these days.
