Alcatel-Lucent Rainbow vs. Cisco Unified Communications Manager (Call Manager)

The main "power" of Rainbow is the hybrid model, to mix traditional telephony and the new way of communicating
Rainbow is used in our company by "mobile" people who need to communicate easily with fixed telephones. For an emergency in a subway station, communications are very important and Rainbow provides everything we need for such communications.

Cisco Unified Communications Manager is suited for medium to large customers who are in search for a solid call control platform with added security in mind. Cisco Unified Communications Manager also supports receptions, small groups and also a mini contact center type of set up with its Hunt Group, Pick up Group and call queuing facilities and also with set up of music on hold function while calls queuing.

• Hybrid communications
• Easy to use
• In permanent evolution
• Not expensive

• This solution is extremely stable and has been running in our environment for several years without (unscheduled) downtime.
• The ability to have voicemails automatically sent as an email message is extremely helpful in helping us to keep in touch while away from the desk.
• The Call Manager provides us very granular settings to route our calls as we want.

Incentivized

• Improve the "bubbles"
• Add more "traditional" phone features
• Improve the conference experiences

• Administration web page is little bit hard to understand at the beginning specially if you are not familiar with naming convention and GU Interfaces.
• Call Detail Record interface is fine but would be desirable to include more options that fit organization needs in terms of reporting purposes.
• Self Care Portal interface could be more useful to the end user if it includes options to manage some features without administrators involving.

We have been using this product for 20+ years and will continue too. This is a great product and new features are always coming out.

The usability part of Cisco Unified Communications Manager is very much simple from a usability point of view. Day-to-day Move Add Change Delete (MACD) can be performed by the administrators very easily with simple training. From the initial deployment point of view, some of the thing can be improved to simplify the process.

CUCM is supported by most third-party vendors for related products, so it makes finding solutions to specific needs easy. Also Cisco TAC is very knowledgeable, and we have never run into a problem they have not been able to resolve. Usually they are resolved without the need to escalate tickers either.

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

Teams have better collaboration features than Rainbow, but for companies like the one I worked for, hybrid communication is essential and Teams can't provide all the phone features we need to work.
Rainbow does a good job for the people who work for our company

We have been a Cisco based shop and have looked at other cloud voice options such as MS Teams pbx, and others, but ultimately, the features, endpoints, and reliability of Cisco has been the common factor in staying with them as our voice provider. Their integrations, room systems, and hybrid design allows for us to be flexible and keep a high up time vs reliance on 100% cloud.

Incentivized

• Gain of time
• Gain of money

• Communication and collaboration - Our offices are able to communicate both internally and externally due to this system.
• Down time - Struggles with CUCM has caused a lot of down time due to the instability of the system.
• High Costs - the cost of both the license and the maintenance was much higher than other systems.
