Cisco Unified Communications Manager (Call Manager) vs. Zello for Work

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.

• Customizability - The program allows for a lot of specific features and ways to use the program.
• Traditional - The system is a very traditional phone system, with everything you would expect and need from an enterprise phone system.
• Expandable - The system allows from a small amount of users to a large amount, with no upper limit.

• CUCM is overly complex and requires a very capable engineer to maintain it. Similarly, implementing anything new requires a great deal of specialized knowledge of CUCM.
• CUCM is difficult to troubleshoot because of it's complexity.
• CUCM is expensive licensing and they nickel and dime you with a plethora of tiny little license charges for every little feature. They have the most convoluted licensing models, ever, for their CU products in general.

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

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 Cisco Call Manager application has been around for much longer than many of the competitors. As such, they have had plenty of time to resolve bugs and increase the feature set that comes natively with this solution. One of the biggest factors for us was the professional services/support that comes along with using any Cisco product.
