    In terms of scaling etc, Asterisk is tons better though as I understand, 3CX uses Asterisk behind the scenes as the engine.

    3CX
    In many scenarios decision is driven by budget and compared to other solutions at the time of purchase [3CX] was simply the cheapest solution for what it has to offer. If you are looking for integrations, extensibility, and advanced functionalities, this might not be a solution for you. At the time of use (and this may have changed by now), there was a lack of APIs, CLI commands, and similar so nothing could be automated with the system. There are ways of importing data through CSV but automation would solve us so much time and support calls if we were able to connect with other systems.

    FreepBX is a great product if you are able and willing to manage your own PBX system. It requires some know-how to set up but once running, it works very well. There is a large community that helps answer questions, but it isn't "plug and play" so you will need to be able to research and troubleshoot your own issues (or pay for support).

    It is an awesome tool for companies that have a hybrid or even fully remote setup and where the integration with Salesforce is needed. The solution completely replaces old phone systems and adds another layer of data to Salesforce, to give an even better view of the interaction with clients, adding automatically events/activities which can in turn be used to reporting purposes.

    Pros
    3CX
    • Simplicity: Using a single 3CX interface we can manage every phone and extension used throughout our company.
    • Flexibility: There are a wide variety of options to configure each extension and phone. Changing anything after the hardware is deployed is very easy.
    • Portability: Phones with 3CX can be easily moved or repurposed within an office or at remote locations, including users' homes. The mobile app allows users to use their office extension anywhere without exposing their cell number.

    Cons
    3CX
    • I would like to be able to see direct-dial numbers on the handsets. Currently that is not possible but that would be a nice feature.
    • You need an SBC per location, which can be a point of failure.
    • You also need a server that might get disconnected, which is another point of failure.

    • Phone integration/firmware can be clunky and has a learning curve.
    • Relies on crowd sourcing information as expected for open-source.
    • Requires some moderate expertise for setup.

    It works well, there isn't much more to say. You can get a free ($0) phone system packed with features, then if you need even more features then the cost is extremely cheap, and it works well. On top of this, you have complete freedom in the PBX to do as you wish, and debug and see everything

    We use the Natterbox CTI interface, seating on top of and integrated with Salesforce. The interface is minimalist, popping up as the calls arrive and bringing the Caller's details if they exist in Salesforce. The user then have the possibility to open the Caller's record and visualise the details and add notes, or make the notes in the pop-up window which will end up in the contact's record activity. Very easy to use. The routing queue interface is also very user friendly with drag and drop items that make it visually easy to read and understand.

    The 3CX Phone System is only a five because while they provide set-up/how-to/Q and A documents to help your district or company get started, they do not offer support for free. The documents provided, though, are good enough for you to get you up and running. We also found a good source of help through a sip trunk provider, which was a 3CX reseller provider.

    The main differences between 8x8, Inc. and 3CX is pricing and ease of use in my opinion. The 3CX system uses annual based pricing plans based on of simultaneous calls your company needs, not the number of extensions/users and offers a free plan. 8x8, Inc. charges per extension with different plans. We currently have 19 extensions so the 3CX system makes more sense for us, however, if your company only has a few extensions you may want to throughly consider both options. In my experience, it was difficult to add new extensions and phones with 8x8 because at least at that time we had 8x8 I could not add anything on the web admin. I had to call a sales rep which took a lot more time. Also, if you didn't purchase a phone and/or headset directly from 8x8 at a usually higher price than Amazon for example then you would have to spend anywhere from 30 minutes to hours on the phone with 8x8 tech support to program the phone to work with the 8x8 system so adding a new extension could turn into a long ordeal. I can easily add new extensions on 3CX directly in the web cpanel. Granted, if you are actually adding a new phone number you would need to purchase that number from a company like ATT first before adding it to 3CX. The difference between a phone number and an extension would be a phone number allows a customer to call in directly using that number. The extension would require the customer to call the main business number then be transferred to the extension. 3CX provides a list of supported phone models on their website

    3CX may be slightly easier for a novice to use, but FreePBX completely beats it when you remove that factor. You can do anything you want, and debug and see everything. Now with AI its even easier to debug and learn how the PBX works if you hit an issue

    When signing up with Natterbox, our first goal was to replace the landline phone system as Covid hit and people moved to remote work. Second goal was to have a system that would integrate with Salesforce and provide an interface that would be easy to work with and learn for all levels of tech expertise. Those two goals were only achieved by Natterbox, by far.

    Return on Investment
    3CX
    • 3CX has a lot to offer for a very low cost as its business model is based on simultaneous calls and not per device. It's very cost effective and very affordable.
    • As the 3CX server does not require a high-performance server to run, with the Public Cloud option, it might allow even further savings.

    • It doesn't matter where anyone is physically located now, everyone can have their calls delivered to their mobile or laptop and answer them.
    • We now have internally the capacity to manage our call queues.
    • We now have a lot of data to report on, either grouping the calls by Campaign on Salesforce, or grouping them by Inbound or Outbound calls, or by User, or by Team.
