3CX vs Cisco Unified Communications Manager (Call Manager)

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.

The Cisco Unified Communications Manager platform would be most suited for the below scenarios. 1. An organization with very restricted policies and compliance where can't move to cloud-based solutions for data security. They can install the CUCM on-premises. 2. An organization that is still on a legacy phone system could adopt CUCM to save costs and have better services.

• 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.

• This solution is extremely stable and has been running in our environment for several years without (unscheduled) downtime.
• The ability to have voicemails automatically sent as an email message is extremely helpful in helping us to keep in touch while away from the desk.
• The Call Manager provides us very granular settings to route our calls as we want.

• 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.

• Administration web page is little bit hard to understand at the beginning specially if you are not familiar with naming convention and GU Interfaces.
• Call Detail Record interface is fine but would be desirable to include more options that fit organization needs in terms of reporting purposes.
• Self Care Portal interface could be more useful to the end user if it includes options to manage some features without administrators involving.

We have been using this product for 20+ years and will continue too. This is a great product and new features are always coming out.

Although it's very easy to use, once you understand the concepts of IP telephony, as I said before, I think Cisco could have improved the management interface of the platform, adding modern technologies and the design language of the other platforms like DNA Center, etc. This interface hasn't had a substantial improvement for about 10 years

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.

CUCM is supported by most third-party vendors for related products, so it makes finding solutions to specific needs easy. Also Cisco TAC is very knowledgeable, and we have never run into a problem they have not been able to resolve. Usually they are resolved without the need to escalate tickers either.

This was the first phone system we implemented that could span multiple locations. We were very satisfied once fully implemented

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

We have been a Cisco based shop and have looked at other cloud voice options such as MS Teams pbx, and others, but ultimately, the features, endpoints, and reliability of Cisco has been the common factor in staying with them as our voice provider. Their integrations, room systems, and hybrid design allows for us to be flexible and keep a high up time vs reliance on 100% cloud.

• 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.

• Communication and collaboration - Our offices are able to communicate both internally and externally due to this system.
• Down time - Struggles with CUCM has caused a lot of down time due to the instability of the system.
• High Costs - the cost of both the license and the maintenance was much higher than other systems.
