Sangoma
Digium Asterisk is well suited for a city government as a communications solution for internal and external use. Other options like PBX are more expensive and hard to escalate. VoIP makes it easier to use the communications infrastructure instead that already exists rather than having to wire every phone when the solution is a digital or analog phone. In my city, government offices are not in the same place, which makes it harder to communicate everything together.

Twilio
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.

Cons
Sangoma
  • I have had trouble having my favorites list from Digium connect to my phone and save my preferences there. I have only managed to do this once, but now we have an added person in our Dept. I can add them on Digium, but my phone does not update.

Twilio
  • 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 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.

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.

I have asked in the not so recent past about having my phone updated with my saved Digium "favorites" list but it doesn't seem that this is possible

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.

Recently I've been using Vonage Business, and while it is far more expensive and a lot less configurable than Digium, the mobility is essential for my new role. Digium is ideal for a business with both a very technical staff and a user base that is not remote. Digium was selected due to price and ability to create custom applications.

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!

  • 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.
