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.

I have tried other competitors. But I always end up going back to Twilio because I feel like it is dependable, easy to use, and, has competitive pricing. The only time I wouldn't recommend Twilio to someone as if they are completely inexperienced about using webhooks or APIs. Because you can't really just sign up and start using Twilio without connecting it to another platform first.

Cons
Sangoma
  • Transferring to a Voicemail is particularly hard to do, and calls tend to drop when transferring.
  • I would like a different interface; the current one feels clumsy
  • Over the weekend, it logs you out, and you have to remember your password or reset it to gain access.

  • Control panel. Often, navigating through lists is challenging. I want endless scrolling, not pagination.
  • Conversational intelligence service require a Language. I would like it to detect it.
  • We would like to have some credit on clients that chose to use their own Twilio account.

Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

Usability

User friendly. Very little training to use it

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.

Twilio executes what it is designed to do: send SMS messages at scale while providing very good deliverability. I believe that Twilio is very good at what we use for adding SMS messages to our comms strategy. We can see those messages get opened and replied to, which is exactly what we are looking to achieve.

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 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.

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.

We evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.

Twilio
  • We found that associates who had the opportunity to respond to a survey about their assigned job were 37% more likely to return to a job site
  • We were able to reduce the number of resources required to manually respond to associates using Twilio Studio, so those resources could have more time to complete other tasks
  • We were able to scale the number of associates who received survey messages at least by a factor of 8 without increasing our resource demand
