CallSource
CallSource was great at seeing where we were failing as a company on the phone calls. It allowed us to tighten up a few spots to close those gaps and increase our call performance.

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.

Pros
CallSource
  • The reporting is easy to access and use with little to no training. Pretty straightforward.
  • It does what it's supposed to -- creates usable tracking numbers, with added features like call whisper and call notifications that can be sent to a number of email addresses.
  • It can be integrated with our CRM, Salesforce, for ease of use!

  • 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
CallSource
  • Phone Call Recording: The only place where I would like to see improvement is the number of calls that you can listen to. Calls are kept in their database for 30 days, and while they do give the option to download the calls I would prefer to be able to login and pull past calls as needed. Past calls, months down the road can be important to clients so they can compare the strength of their sales teams and see where improvement is needed. It lets you monitor overall campaign effectiveness, and if Callsource added this feature then they'd be unbeatable.

  • 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'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.

Others are similar, but this is a simpler format, quick e-mails going out and easy to make changes to the system rules for adjustments

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.
