Overall Satisfaction with Cisco Unified Communications Manager (Call Manager)

We use Cisco Unified Communications Manager across our entire organization. This includes 30+ sites and about 1,200 phones and users. This allows for easy four digit dialing between offices and provides organization wide voicemail and instant messaging and presents. The system also allows us to receive calls originating from location and answer from another to provide better coverage between departments and regions.
  • The first strength is this is a VoIP system allowing voice to travel across a data IP network. This makes cabling for phones very easy as the phone will utilize the same network cable that your PC would. This also means less infrastructure to support voice. No need for large PBX systems and closets that hide cabling nightmares.
  • Cisco Unified Communications Manager is a very flexible product. It can be custom configured to best suit your business needs and locations. It can be used as a single tenant or multi tenant system. Each site or office location can be configured separately from others for greater control.
  • Cisco offers a wide range of phone models for various needs and supports many third party SIP phones. There are also multiple ways to integrate with legacy systems during a system migration or when integrating a new company or office.
  • Licensing can be difficult to understand. Cisco has changed licensing models multiple times over the years and determining what modes is best suited for your company can be difficult.
  • Systems backups need some work. If you are in a multi server geographically separated environment backups can be a problem. All servers are included in a backup session and if servers are across a WAN connection all that data is being pulled across the WAN. I would like to see cloud backup or multi location backup options.
  • When phones move between sites/subnets it would be nice to have a feature that could automatically move the phone configuration from one device pool to another so that location specific options are set for the moved phone.
  • A positive impact would be we no longer need any expertise to manage a legacy PBX system and running out of ports for users.
  • A negative impact would be as we grew we found we needed more expertise with Cisco Unified Communications Manager. This required additional training and time.
  • A positive impact is with many of the other applications that utilize Cisco Unified Communication Manager we have a more collaborative user base.
I have not used any other products like Cisco Unified Communications Manager.
Cisco TAC support specialist are very well trained and are responsive. They escalate the issues if need and provide excellent support.

This was the first phone system we implemented that could span multiple locations. We were very satisfied once fully implemented
