Overall Satisfaction with Cisco Unified Communications Manager (Call Manager)

Call Manager is used for our organization and for telecommunication services for all our offices globally. It provides us with seamless voice and video communication and reduces cost incurred with Telco as we route all calls within the organization internally across our WAN,
  • Call Manager provides no-cost communication between all our offices globally.
  • Call Manager administration is easier than traditional TDM and or other VoIP systems
  • We used to be a full Cisco shop with Cisco routers and switches. However, we've changed our infrastructure to use Brocade and it works well with other systems.
  • It would be nice if Cisco-provided better management tools. We used to use Prime Collaboration but moved over to Riverbed UCExpert
  • Our offices can sometimes fall victim to robocalls so it would be nice if Call Manager had an easy way to reject these calls instead of doing it on the cube router or provider side.
  • I've been using Call Manager for a while now and I find that with each subsequent upgrade that it gets better and better. Maintenance upgrades can sometimes be difficult and I'm not sure how to address it but I've been using a new tool called Prime Collaboration Deployment that's helped. I think in general CUCM is a great product.
  • Since we did transformations of all our offices from Nortel to Cisco we have not needed maintenance support from local vendors in the offices. We've centralized all support of the offices globally to our corporate site.
  • We leverage our WAN and route all internal calls within our sip trunks and save cost from our Telco providers eg AT&T, British Telecom, etc
  • We've leveraged the other tools that have worked well for our business eg Jabber for PC, iOS and it's helped our communication process within the organization as well as with our clients.
  • Cisco Unity and Cisco Expressways
We've never thought about using another product other than Call Manager. I believe Call Manager has the lion's share of the market at the enterprise level. I used to be an Avaya Engineer but moved my expertise to Cisco Call Manager. I believe it's a great product and management and ease of use is great. I also moved from Avaya to Cisco as a way to leverage my career.
I used to do Avaya TDM and Avaya VoIP but that's been over 10 years ago. Honestly, I don't think there's a product that competes with Call Manager on the Enterprise level. I believe it's come a long way. We use Cisco 8800 / 9900 devices as well as Jabber and MRA to connect our remote users. We also leverage other products such as voice messaging with Unity Connections. I've also used other products such as Contact Center Express.
