Gerente general de ingeniería Small-Business (50 or fewer emp.) 3/5/2020 "CUCM - Great experience" 5/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

Customer Service Specialist Telecommunications Enterprise (\> 1000 emp.) 10/2/2019 "Excellent feature set, average operability" 4/5 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. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? When working with large amounts of data it can be quite slow. For example, if you need to run a report which details the total number of each individual device type, or pull out a list of every MAC, and associated details, for every single instance of a particular model, we have to run the reports outside of office hours as it slows the system down which affects the users’ experience. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? It was installed as a replacement for an old analogue phone system. The CUCM system has made everything so much simpler to manage, and added a much wider feature set which also enables us to easily add new features and services as and when required.
