Cisco Unified Communications Manager (Call Manager)

Regardless of everything, no one can argue that the CUCM is among the best, especially when you’re using Cisco Phones. So, unless you’re on a very tight budget or have multi-vendor phones, don’t go for 3rd party systems, as they lack the simplicity of configuration that is built-in within the CUCM. Having everything within the Cisco ecosystem will exponentially lower the time required from IT to configure and manage.

I think OnSIP is well suited to be used in any organization that has a stable, reliable internet connection. The service is top notch and I haven't found a competitor that can beat the service. I've recommended the service to other manufacturing businesses and churches. The organizations that have switched have been extremely pleased with the service.

Cons

Cisco Unified Communications Manager (Call Manager)

  • 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.

  • Accept more phone brands/models
  • Make your website easier to use

Although it's very easy to use, once you understand the concepts of IP telephony, as I said before, I think Cisco could have improved the management interface of the platform, adding modern technologies and the design language of the other platforms like DNA Center, etc. This interface hasn't had a substantial improvement for about 10 years

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.

Alternatives Considered

Cisco Unified Communications Manager (Call Manager)

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.

OnSIP

We have found OnSIP to be just as good if not better than any of the other services we have researched or used. Once again, the value of OnSIP is unbelievable. Our rates at this organization are less than half of what the competitors were charging. I don't see us changing anytime soon.

  • 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.
