    These are not dedicated IP phone systems but they are the close I've used. Our old legacy phone system wasn't cutting it anymore. I would say our biggest hurdle for out-groups has been able to get the old legacy fax services working for 3CX and I'm not sure if it even does. …

    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.

    It's amazing as a daily driver for team communication, and document search/store. Also, if you're doing a lot of LONG meetings and have trouble remembering details, the AI summarization is amazing and convenient. It just works. I'm not saying I always do this, of course, but if I need to 'skim' instead of really digging into every detail from a meeting, the AI-generated summary is generally good enough that I can get away with it.

    If you have more than 2 people in your organization, then this will save you so much time. Delegation is the key to starting a business. Even when you're a 1 person show, being able to present to your user base the differentiation of options for client communications is critical. As a founder, feeling compelled to be always on is something I strive not to be. OpenPhone gives you that flexibility. I have found it to be less appropriate in complex HIPPA compliant areas, but that is it. OpenPhone really does seem to suit an open array of use cases.

    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.

    • The webinars feature has some missing functionally such as the ability for all users to use the Q&A feature (only those with a Microsoft Teams account can use it now), the ability to upload documents for attendees to easily access and download, and the ability for presenters and organizers to easily chat amongst themselves throughout the webinar.
    • The "Channels" organization hierarchy could be more clear. If you have several channels set up, it can get clunky and hard to find the specific channel you are looking for.
    • The MS Planner tool lacks functionality and organization. You cannot assign more than one person to a task and it's confusing when you try to share tasks with people - it would be nice if they were automatically added to someone's calendar.

    If you have the full Microsoft Office suite, it works really well because it's integrated well within its ecosystem, but if not, it can be annoying because it tries to open a shared file in the web versions of the file equivalents. The web version is also a bit slow, and the login is very difficult to handle if you have multiple Microsoft or Outlook accounts.

    In my experience, App features are buggy and confusing, and they often don't match the descriptions and screenshots in their documentation. In fact, many of their help links go to 404 "page not found" errors. In my experience, there are frequent outages and quality issues. My customers prefer to talk to me on a different line, because they find it difficult to understand me on OpenPhone.

    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 overall support provided by Microsoft for Microsoft Teams has been quite good but there is still some room for improvements. Microsoft needs to proactively work on fixing the open bugs in order to provide a seamless experience to the users. But over the service and experience provided by the Microsoft team have been quite satisfactory.

    In my experience, their support feels like the opposite of support. They send you in circles, never directly answer questions, provide vague suggestions with unwanted platitudes, and they often take days between responses to provide that. For me, it's a frustrating experience that leaves you with a net loss of time and energy versus before you reached out to them. In my opinion, you definitely don't get "support".

    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

    Microsoft Teams offers a much more integrated experience between their chat and video call function compared to Google Chat and Slack. Both other tools are much better for internal communications are they have simpler UI without other features. Whereas Microsoft Teams can be used for more critical conversations, particularly between external companies, and has been very useful in sales conversations which is what we chose it for when speaking to companies that work exclusively through Microsoft.

    OpenPhone has an easier user interface than Grasshopper. Years ago when I was using Grasshopper, I recall that their user interface looked antiquated and full of complications. They would also update the interface just as everyone was getting used to using it. OpenPhone has many more functions. Grasshopper's app did not offer basic functions such as in-app texting between team members, and its call transfer function was incredibly complicated to use. In my opinion, Grasshopper was an inferior service/product in almost every way.

    • 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.

    • Personally, I would say that by using Microsoft Teams, it upped my collaboration with my colleagues by around 50% or around more than half of what I usually did prior to using it.
    • I had 100% show rate and attendance on all of my meetings in the past 6 months.
    • If I may add, I also have been chattier & collaborative towards my colleagues in past 3 months particularly the month of December when we had huge traffic at work. I would estimate this behavior to have been increased by around 60% than what I usually incur during normal operating days.
