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.

Twilio excels in customer service applications, enabling automated SMS updates or voice calls for order confirmations and support. It's ideal for implementing two-factor authentication, enhancing security for online services. However, it's less suitable for businesses needing in-depth, custom telephony infrastructure, as it primarily offers standard, API-driven solutions, or for regions with limited internet connectivity, where cloud-based services may be unreliable.

Pros
Cisco
  • 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.

  • Easy to see my team in one place, when they log in and out and what call status they are in.
  • Twilio is a simple, user friendly way to log in and out of work activities.
  • Excellent services and support.
  • The omnichannel feature which allows agents to get request from all channels.

Cons
Cisco
  • 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.

  • In my opinion, online support is extremely subpar for clients.
  • In my experience, no way to talk with anyone without a $1,500 investment monthly in their service.
  • In my experience, be prepared to wait at least 2-4 days to receive even one response from their support.

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.

We have standardized our processes surrounding Twilio. The entire process just works! There is no significant gap that we need to fill. Instead of thinking about Twilio's replacement, we'd rather focus on our customers with Twilio. It meets all our uses-cases currently. We haven't even explored the entire suite of applications to determine what other use cases we may potentially use.

Usability
Cisco
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

Overall the product API is extremely well documented so it is very easy to build a product with their technology. The website is a little bit cumbersome to use as they have greatly expanded the number of products that they have over the years, but the dashboard UI has not been improved much since.

The problem tends to be us, the user, rather than Twilio. We don't reach out to support fast enough (spend time struggling), but when we have, they've solved our issue immediately. We are rural, so there are signal issues to accommodate, however, we find that a few staff on a few cellular networks can triangulate where we all have signal to put up a sign.

Support Rating
Cisco
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've never had to contact Authy's support. Of course, that's because Authy is so simple and easy to use that there hasn't been any need to. Authy correctly implements the time-based one-time password (TOTP) protocol, and becomes it conforms to the standard, it easily replaces Google Authenticator for your needs.

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.

Twilio was referred to me by a business colleague, and I can't be more thankful! Twilio has helped my Facebook page by leaps and bounds, and I haven't even considered trying another chat option for my page. It is easy to set up, and customer service is quick to answer any and all questions you may have. I highly recommend it!

Return on Investment
Cisco
  • 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.

  • Adding in phone numbers onto our onboarding sequence has increased our user activity by about 30%. We believe due to the users being more invested in the application now.
  • On top of that, our first SMS has increased our week 1 retention by about 15%. Pushing users to go on the app more than 2-3 times has been a struggle and SMS seems to be a solid driver in retention.
