MiVoice Business is a unified communications platform from Canadian Mitel Networks Corporation, for businesses with 5 to 65,000 potential users.
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.
As a phone system, MiVoice Business is absolutely fantastic. It's equipment and even virtual appliances are extremely stable. Simple auto attendants and making/receiving calls is where the strength is. Where is needs help is the Windows-based software. Upgrading this can be extremely difficult and it frequently fails for no reason. Services stop running and needs frequent reboots. The client has improved greatly with newer releases but can be buggy. Sadly, the old ways of a traditional desktop phone is dying and I think MiVoice Business isn't as good as some other options that provide more. The end user client just isn't as stable as something like Microsoft Teams or Zoom Voice that can provide a more stable soft phone experience.
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.
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.
I've used MiVoice Business at multiple employers. Once of them was moving from a very old Avaya PBX, another was with an NEC phone system that was slightly newer. MiVoice was far more easier to setup phones, setup users, manage voicemail, ETC. While we had consultants perform any upgrades with Avaya and NEC, MiVoice we did more collaborative with our support partner but we ran into far more issues with upgrades of MiVoice. My last 2 companies have discussed moving their phone system to Microsoft Teams and my current position they've already done that. All the issues with MiVoice relating to upgrades and issues with the Connect client are not existant with Teams. Teams is the bar, sadly MiVoice Business - while a very good product - falls short. They just haven't yet resolved issues that have long existed and in a pre-covid world it was OK. Now that people are displaced, the office environment has changed and end users are not isolated to a desk with a physical phone. MiVoice Business needs to catch up.
