DS Donald S. Director of Technology Services Farming Mid-Market (51-1000 emp.) 11/17/2016 "Best of Breed" 5/5 What do you like best about Cisco Unified Communications Manager (CallManager)? I've been using, and involved in deployments of Cisco Call Manger dating back to 2005. The greatest compliment that I can give the solution is that the platform stability is "rock-solid" and the solution is extremely dependable. Personally, I've never engaged with anyone that has Cisco Call Manager that isn't pleased with the solution. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? I believe that Cisco is still playing catch-up in a few software areas, and you're required to purchase some additional 3rd party tools to perform basic functions such as detailed call reporting. However, I do feel that Cisco continues to close that software gap, in some areas, between them and their competitors. The biggest challenge is the complexity of the overall management of the platform. Once you're used to it, managing Call Manger is easy, but the learning curve to get there is steeper than other solutions. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): Personally, I feel that it's the platform of choice, but you need to consider how it will be administered and supported internally within your organization. The initial complexity of the solution can be overwhelming if you're not prepared. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? Other than the obvious basic dial-tone, we use it for it's soft-phone capabilities, single number reach, instant messaging, call control and flows, and unified messaging. It's a great help to our mobile workforce and users that migrate between our 30+ locations. Review collected by and hosted on G2.com.

MD Michael D. Network Administrator Senior Industrial Automation Enterprise (\> 1000 emp.) 11/9/2016 "CallManager Use for business" 5/5 What do you like best about Cisco Unified Communications Manager (CallManager)? The ease of Maintaining Phone system once it is installed and configured. Adding and removing users and phones to the system are pretty easy. Also reconfiguring phones are simple. I like the fact that the phones are basically computers and can be moved anywhere on the network and retain all setting and numbers. And now no need to have a telcom contractor come in and repunch the phone jack. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? The complexity of upgrading the Hardware if expansion is needed. It is not always as easy as just adding memory. When you scope out the servers needed make sure you scope for extra growth within the company. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): It is a very good and stable product. There is a great deal of options that you can do with the Call Manager Suite. If you have a large IT staff you can dole out roles for each member to be responsible for different aspects of the system. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? Getting away from a technology that is end of life. Getting a handle on all the City's phone charges. We saved a lot of money by eliminating phone number that we don't use and ones we found haven't been used in years but nobody knew what it was but still were paying for it.

Head Golf Coach and Director of Club Sports/Intramurals Mid-Market (51-1000 emp.) 7/26/2016 "Great product!" 4/5 What do you like best about Cisco Unified Communications Manager (CallManager)? This is a great product to go with our Cisco phone. It makes programming it easy. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? It was a little overwhelming at first with so many options from the phone we had in the past. A detailed instruction book on all that your phone is capable of would have been nice, but otherwise, I found many of the features very helpful and am still implementing them. The speed dial feature is nice, but I was unsure of how to use it at first. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): Have a training session and really learn how to use all the features available with the CallManager. A lot of the tools can be helpful, but if you do not know what you are looking for, you may have some difficulty in harnessing all the resources available to you. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? I am not really solving any problems, but from the phones our organization had in the past, this is a huge upgrade. I love my Cisco office phone, and can't imagine using another one.

Extremely stable, feature rich product. Easy to manage multiple endpoints. If uptime is important to you, Cisco UCM is a fantastic. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? We have to use a third party for the hospitality portion (DuVoice, which works very well). A few competing products have the hospitality functions built in. Built in conference bridge (if you can call it that) is lacking, Cisco pushes WebEx which for our purposes is a bit overkill. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): There may be less expensive options on the market, but if you are looking for a solid reliable product that will last many years and is backed by Cisco's unmatched warranty/support take a look at Cisco UCM. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? As the solo administrator of a 200 node Cisco phone network, reliability is crucial. UCM runs on top notch Cisco hardware that I can confidently rely on every day. The overall administrative time to manage this system for our needs is a fraction of what our previous system required, which in turn has saved the company thousands of dollars and me countless hours of administration.

I like that the phone is very easy to use. There are few buttons, so it is easy to keep track of where you are at and what you are looking for.

It's nice not to have to dial in a password, but have it on my computer to look at. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? I dislike when I have to call tech support for some things. Most items should be self explanatory or able to find it on the internet. tutorials are great! There should be more internet tutorials on how to solve problems on our own.

UI / UX Designer Government Administration Mid-Market (51-1000 emp.) 6/16/2016 "Great Communication Tool" 4.5/5 What do you like best about Cisco Unified Communications Manager (CallManager)? Cisco Communication is a great tool that connects you to the rest of your company. It allows you to shoot quick chat messages to people (or groups) allowing you to continue your work while collaborating with co-workers in an instant messaging format. This is great because it means as long as you have a computer with you, you can contact anyone with quick questions (especially helpful in meetings so you have more proactive to-dos). It's also nice because it allows you to integrate it into an excel spreadsheet that has a bunch phone numbers and you can use your computer to make those calls. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? The instant message feature can be a bit distracting because people do assume that if they shoot you a chat message that you are expected to reply back quickly, which inevitably distracts from your work, so it's not always ideal Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): It really is a great tool to help an enterprise stay connected, but it does take a bit of effort to get everyone to adapt to using it and making sure that everyone logs into it each morning. It does have statuses that you can apply to it so you can prevent people from calling/messaging you or to notify someone when you're away from your desk so they don't waste time going over to your desk to ask a question. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? It is helping with overall company communication. If I can still get in contact with you while you're on the phone or if I can call you with a click it really helps make sure that productivity stays up. Review collected by and hosted on G2.com.

"CUCM currently the best enterprise solution for call routing" 3.5/5 What do you like best about Cisco Unified Communications Manager (CallManager)? Currently compared to the alternatives Cisco Unified Call Manger is the best option for enterprise call routing. I work in call manager every day, and have had experience with many of the alternatives, including microsoft and avaya's offerings and call manager is by the far the best offering. It has come a long way in the past few years and is relatively easy to administer (albeit maybe not to architect for). I'm hoping it will continue to improve to keep up with an evolving market. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? It has integration issues most frustratingly with its own platform. This is most obvious currently with integration with UCCX and IM&P. Review collected by and hosted on G2.com.
