Excellent Solution with Robust Features **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Education Management | Mid-Market (51-1000 emp.) **Reviewed Date:** May 05, 2026 **What do you like best about Cisco Unified Communications Manager (CallManager)?** The system can support thousands of users and devices with high availability options, which is essential for large enterprises. CUCM integrates very well with other Cisco collaboration products such as Unity Connection and IM&P, providing a complete unified communications solution. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** Licensing and maintenance expenses may be somewhat higher than those of certain alternative solutions. Additionally, the administration panel's user interface is occasionally less intuitive, which can make troubleshooting more time-consuming if you lack the necessary expertise. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Cisco Unified Communications Manager (CUCM) stands out as a robust and widely adopted call control platform, specifically tailored for enterprise-level telephony systems. Its comprehensive feature set and dependable performance have made it a favored solution among large organizations. ### 2. Feature Rich but Complex **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** July 31, 2025 **What do you like best about Cisco Unified Communications Manager (CallManager)?** CUCM is a feature rich VOIP solution solution that can handle any business voice needs. From external network calling, PLAR's (private line automatic ringdown), hunt groups, call forwarding, app support. My organization has yet to find something CUCM cannot support. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** CUCM is very complex. While it is feature rich, every advanced calling feature requires an additional server, which often leads administrators wondering what server does what? It does create some stress keeping up with patching, server administration/management, etc. I have experience with other solutions that are able to provide a feature rich experience in a single pane. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** CUCM is a reliable VOIP solution that I have no doubt can scale to any business size and needs. ### 3. Product is OK but the service and support is a dumpster fire **Rating:** 0.5/5.0 stars **Reviewed by:** Ciprian G. | IT Director, Mid-Market (51-1000 emp.) **Reviewed Date:** September 10, 2024 **What do you like best about Cisco Unified Communications Manager (CallManager)?** It checks the boxes for minimum required features for a phone system. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** The system is incredibly complex, UIs are almost intentionally hard to understand and are almost never updated. Everything looks like it was built in the 90s because it probably was. Getting service and support on anything in the system is just as painful as getting support from Cisco on anything else. They make you jump through hoop after hoop regarding service agreements, licensing, user assignments and access. You'd think you were trying to break into Fort Knox every time you need help with something. This also seems intentional, you don't have to pay your support team as much when customers will just give up and workaround the problem rather than try to get help from you. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** It allows you to make phone calls. Whoop dee doo. For the price Cisco charges you would think it would do a heck of a lot more than that. ### 4. The Ferrari of Phone Systems **Rating:** 5.0/5.0 stars **Reviewed by:** Claudia K. | Senior Manager, Telecom Contact Center Operations, Enterprise (> 1000 emp.) **Reviewed Date:** November 09, 2023 **What do you like best about Cisco Unified Communications Manager (CallManager)?** As someone who has supported CUCM for several years, I can safely say that it is a workhorse. It's stability can be rivaled by only a few other pbx platforms, in my opinion. While there is a slight learning curve and of course requires the proper Cisco training and subject matter expertise to set you up for success, after proper hand-off the platform can be supported easily by analysts and will run-well for the most part. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** The frequency with which you must upgrade to stay current may be a concern for larger entreprises. This can put you in a position were you are severely behind on version and have to scramble. It is important to plan ahead and make time for those upgrades to minimize overall work and impact to the business. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Cisco is a robust pbx application, it provided voip service to our contact center and our admin staff. During covid , we were able to leverage Jabber to help transition our 2,000 contact center agents home in less than 72 hours. ### 5.

My review of CUCM **Rating:** 4.0/5.0 stars **Reviewed by:** Mohammed T. | Network Administrator, Small-Business (50 or fewer emp.) **Reviewed Date:** March 12, 2022 **What do you like best about Cisco Unified Communications Manager (CallManager)?** The quantity of features supported by cucm is astonishing, and the gui is simple but easy-to-use **What do you dislike about Cisco Unified Communications Manager (CallManager)?** The pricing, a lot of companies won't consider using it because of the licensing which is expensive **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** A reliable call manager that is tested and can perform at the highest level of of efficiency ### 15. nice tool for communication **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Telecommunications | Enterprise (> 1000 emp.) **Reviewed Date:** May 24, 2022 **What do you like best about Cisco Unified Communications Manager (CallManager)?** a good communication tool especially when you can make call forwarding on your mobile when you are not available **What do you dislike about Cisco Unified Communications Manager (CallManager)?** audio breaks some noises and audio distortion **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Interoperability and standards support.

CUCM - A great product that works. **Rating:** 4.0/5.0 stars **Reviewed by:** Andrew L. | IT Systems Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** April 13, 2021 **What do you like best about Cisco Unified Communications Manager (CallManager)?** I like how well it works and integrates with our existing Cisco infrastructure as well as other third part products that we use. Everything just seems to work. Now that I have worked with it enough, I am comfortable making changes for when it is needed. It sync with LDAP which makes it nice for new users as well as using the Quick User feature to quickly assign a phone to an end user. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** I would say if you need to make a configuration change, then it can become a challenge if you do not know enough about the system and what things will do. There are many menus within CUCM and you don't want to make a wrong change. I wish the UI was a little more friendly, it does seem a bit outdated. But, I get it, it works, so why change it. Additionaly, as everything Cisco, I do dislike the yearly suspport to pay to get any upgrades or to get a hold of Cisco technical support. **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** If you are in the market for a new phone system, I would consider this on premise\cloud solution, it may cost a bit more than some, but it is definitely feature full and things just work. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** We are getting flexibility to be able to plug a phone in any ethernet port and have it just work. Having this system over an old analog system allows us to manage it better than hiring someone for our old system. We also have the benifit if we can figure something out, we can just search the Internet as this is a widely known system and there is bound to be an answer for our question. ### 17.

CUCM in it's current state uses very outdate and unintuitive user interface **Rating:** 1.5/5.0 stars **Reviewed by:** Tremaine W. | Interior Design Architect, Mid-Market (51-1000 emp.) **Reviewed Date:** March 18, 2021 **What do you like best about Cisco Unified Communications Manager (CallManager)?** Its flexibility and wide adoption among many industry leaders **What do you dislike about Cisco Unified Communications Manager (CallManager)?** The Cisco TAC support team often fails to take ownership of issues and it's very rare that you'll receive a competent call manager engineer to assist you with configuration. It has been my experience that their default is to push the issue on another vendor. **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** I could only recommend the cloud iteration **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** It works. Though unintuitive, it does provide the business functionality we need. That said, we are investigating cloud options that provide a better UI for our agents with fewer complexities. ### 20. Making work from home easy with quick connect **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** August 10, 2021 **What do you like best about Cisco Unified Communications Manager (CallManager)?** Easy communication and connect with teammates. Great video calling. Work well with Less internet bandwidth Speed. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** Chat history is not available sometimes.

CUCM Solution Architect **Rating:** 5.0/5.0 stars **Reviewed by:** Pramod C. | Infrastructure Solutions Architect, Enterprise (> 1000 emp.) **Reviewed Date:** June 25, 2021 **What do you like best about Cisco Unified Communications Manager (CallManager)?** WEb GUI and Cluster management of Unfied Communication Platform to amange IPT **What do you dislike about Cisco Unified Communications Manager (CallManager)?** Additional Linux REAl time Tool Integration Piece **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Unified Communication HSC Platform ### 22. CUCM - Great experience **Rating:** 5.0/5.0 stars **Reviewed by:** Oscar A. | Gerente general de ingeniería, Small-Business (50 or fewer emp.) **Reviewed Date:** March 05, 2020 **What do you like best about Cisco Unified Communications Manager (CallManager)?** I like how easy it is to use. Making changes like extensions, phones does not take me long. That it can connect to LDAP or Active Directory is a great advantage since it simplifies the administration of users. The fact that it handles SIP protocol makes it ideal for communicating with third-party equipment. Being able to manage high availability systems is a great advantage to keep the equipment always working. And together with the manufacturer's service where they have record response times, it makes it ideal for companies that cannot afford to stop. Features included in licensing like Unity and IM & Presence Server make it a great option. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** I think the main disadvantage is the cost. For many companies that do not require all the features that the Call Manager can offer, the cost cost may not be what they are looking for. Having multiple servers for high availability can be expensive too. I also think it lacks an option for small or medium business. Before, it had the BE6KS, which was for up to 150 users. I do not like that this option is no longer available. It was really economical and helped us for the remote offices of few users who could not connect to the central site. **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** I recommend reviewing the issue of licensing well. Adjust it only to the needs they may have at the moment, with a percentage of expected growth in the next 3 years. If they acquire it in a lease plan, consider the service and growth they may have during that period. Failure to review or size the licenses properly could result in excessive and unnecessary expenses. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Communication with third parties mainly. We have managed to integrate with business partners that do not necessarily use Cisco. ### 23.

TAC is available 24/7 so if you run into problems, you can call them up anytime. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** CUCM sometimes does not "do" things logically but once you get used to how things work, then it's pretty good. They have a lot of bugs but a lot of them get addressed pretty quickly. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** I have been planning, designing and troubleshooting voice for the last 15 years ### 24. is very reliable and easy to manage. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Mid-Market (51-1000 emp.) **Reviewed Date:** August 13, 2020 **What do you like best about Cisco Unified Communications Manager (CallManager)?** Cisco Unified Call Manager provides all the bells and whistles a company that wants to succeed will ever need, it will also grow with the company. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** Initially, it is difficult to administer and not very intuitive. **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** Do your homework and hire a system administrator that is familiar with the UC platform. **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** Many of the features CUCM offers make it easy for my team to communicate with each other without a loss of productivity. ### 25.

I strongly recommend Cisco Call Manager because as Admin user gives you a lot of benefits in your compañy. Easy to set up phones and templates. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** The only thing I don't like about Cisco Call manager is that new models or versions increasingly divide the features that you can use and this requires additional licensing that sometimes is not planned in your master plan. **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** Great Cisco Solution **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** the problems I've been solving with Cisco Unified Communication Manager is the lack of communication with my end users when they try to contact other peers in other factories, the use of mobiles increase a lot the cost and with cisco, this problem dissapear. ### 27. Cisco Unified Communications Manager - Axel Olivares Review **Rating:** 5.0/5.0 stars **Reviewed by:** Axel David O. | IT Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** September 22, 2019 **What do you like best about Cisco Unified Communications Manager (CallManager)?** The interface is an interface that helps me a lot to make the necessary settings such as registering a user, a device without problems. It is a very robust system that I like very much I have had the opportunity to use other similar solutions and I would not exchange Cisco for anything. The CUCM can be adapted to several Cisco solutions to keep everything integrated including video conferencing rooms or meetings **What do you dislike about Cisco Unified Communications Manager (CallManager)?** Although the interface helps you a lot by being very clear, sometimes to do something simple you have to indicate several settings or adjustments, this may be complicated for someone inexperienced **Recommendations to others considering Cisco Unified Communications Manager (CallManager):** Read and understand very well the type of licensing that exists for the CUCM since this can greatly increase the cost of the project if it is overlooked **What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you?** The problems that have been solved have been such as: just being able to use the telephone service in your workplace so we have gained the benefit of having the service remotely, being more agile with our work by having a tool that unifies services such as chat, voice and telephone as well as presence, if we have to move from a place and we are waiting for something important we can continue to connect without problems to the telephone service. ### 28. Excellent feature set, average operability **Rating:** 4.0/5.0 stars **Reviewed by:** Andy H. | Customer Service Specialist, Telecommunications, Enterprise (> 1000 emp.) **Reviewed Date:** October 02, 2019 **What do you like best about Cisco Unified Communications Manager (CallManager)?** The wide range of options for finding a particular device or extension. If you don’t know the basic extension number or MAC there is always still a way that you can find what it is that you are looking for. It’s a great tool for management of a large fleet of devices. **What do you dislike about Cisco Unified Communications Manager (CallManager)?** When working with large amounts of data it can be quite slow.
