The Cisco Unified Communications Manager platform would be most suited for the below scenarios.1. An organization with very restricted policies and compliance where can't move to cloud-based solutions for data security. They can install the CUCM on-premises.2. An organization that is still on a legacy phone system could adopt CUCM to save costs and have better services.

If you have a business page on Facebook, having Twilio’s chat not feature is a must! No more missed chat messages or clients getting upset because of a delay in replies. Twilio has helped on several occasions answer simple questions, so I didn't even have to answer the chat message manually. It also enables you to recognize when spammy messages are trying to get through.

Pros
Cisco Unified Communications Manager (Call Manager)
- 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.

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.

- Setting up response sequences should be more intuitive like an email sequence software or a chatbot service where you can send users through flows based on actions.
- Less code setup or having a graphical user interface to set it up would be nice then to be able to just export the code of what we need and send it over to developers.
- Easier multi-media sending for images, videos, or files needed.

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

Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

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.

I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries.With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.

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.

I receive regular unsolicited communications from Twilio competitors but I do not have the time to review them, given there is no reason for me to switch. Twilio works great and its pricing is acceptable for our situation. Investigating point solutions for text only or voice only would complicate our infrastructure and vendor management and would require some expensive system changes.

Return on Investment
Cisco Unified Communications Manager (Call Manager)
- 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.

- Twilio WebRTC allowed us to move a bulk of our communication to the cloud, giving us a lot of visibility on how we were communicating with our customers.
- It also gave us analytics on how much time users spent on communicating with each other over calls and helped us build features around it.
- Twilio became the center of all communication on our platform. From chat messages to phone calls, it powered everything.
