Google Voice and Twilio both provide phone numbers; however, Twilio allows you to program how to respond to voice calls. We have only used a small portion of what Twilio is capable of. I appreciate being able to get information about a phone number to see the provider and …

I do think Google Voice works well for organizations that do not have a support team meant to provide regular telephone support, and instead do so on an ad hoc basis. I would not recommend it for high-volume call activities, such as SDR motions.

Twilio
I found Twilio to be excellent and very easy to use for a programmer in all aspects related to voice, SMS, and other features utilizing their API. I found the node client to be excellent and helpful. We previously used the Apex client for Salesforce before it was discontinued. Although we try not to use Twilio from Apex anymore, using that client was easier than implementing our own.

If you cannot use another more common solution on the market or are looking for an alternative to the known solutions, it is a great alternative. If you have other tools already, and just want to test [them], that's fine, but I think the better-known ones have a better chance of using, knowing, and the learning curve will be shorter.

Pros
Google
  • Google Voice has been great for setting up additional phone lines and numbers.
  • The voicemail inbox is a great feature and you can see when messages come in online and listen to the messages from your computer.
  • Google Voice allows us to have multiple phone numbers and lines for specific business purposes.

Twilio
  • 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.

  • Easy to use: The app is very, very easy to use. Literally just create a chat room (input a name) and access it to chat.
  • Call/video quality: I've experienced better call quality on appear.in than in almost all other chat and video conferencing services out there.

Cons
Google
  • There has not been much innovation since the initial release.
  • It doesn't handle SMS well.
  • It does not natively integrate with CRM without legacy complication
  • It is not supported by Google as it once was
  • Call Recording is non-existent
  • Call-Tree or Virtual Auto-Attendant needs are not available

Twilio
  • Segment’s email identifier is case-sensitive, which is ridiculous because emails themselves are not case-sensitive. This means that if I send a capitalized email address in an identify call, it will create a duplicate user rather than matching it with the lowercase email. I think this is a technical oversight that should be corrected.
  • I’d like to see more information about the eventual transition of existing Frontline customers to Twilio Flex
  • I’d like to see some integrations between Twilio Studio and OpenAI or another open source LLM to provide automated responses, if this hasn’t been done already
  • I would like to be able to drag and move the actual lines connecting the steps in Twilio Studio, sometimes mine can get pretty messy
  • I think a Bug Report form would be beneficial for developers

  • The paid version may have dial-in. But I have always used the free version. Dial-in is typically required for an "official" multi-purpose teleconference platform.
  • I did have some trouble with larger groups (5+) when it was Appear.in but almost always use it for small 1-on-1 or 3 person meetings.

Google Voice has been invaluable for us in our effort to provide exceptional customer service. With Google Voice, we have been able to increase our customer interactions while reducing the wait time to reach a live person on our team. We couldn't be more pleased with the way things have worked out since implementing Google Voice.

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.

We are using a larger tool suite that already includes video conferencing instead of our older approach of using different apps from different vendors. appear.in has a simple but great set of features but its pricing scheme is not as scalable as we really need in a 500+ employee company.

Usability

I think it works really well in the arena it operates in, but not so well in areas where an enterprise system would be more appropriate. It's great for quick solutions that just work, but not so much for more complex call management tasks.

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.

Support Rating
Google
They do not offer support unless you have the Business account for Google Voice under G Suite. This is tough, because Google doesn't really have a customer support team for this service, so when it gets shut down for a few hours, we have no choice but to wait it out. But this doesn't happen that often, which is great.

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.

Never had to contact support, so we cannot give a rating for their overall support. When we noticed the audio was not always great quality, we simply educated our users to mute the mic and use the in-room conference phone which is connected via a dedicated VOIP link and had much better voice quality. The video performance varied by locations network speed and found it got much worse when the room size increased to over 4 connections.

Alternatives Considered

The integrations of Google Voice with all our devices are flawless, Android, iOS, Windows, Linux and Mac. Also, the call performance is far superior on wifi as well as on mobile data. With Skype, we had several problems with personal accounts, performance issues, and in general, it felt awkward to use it.

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.

I find Zoom more complicated to use and harder to use because a lot of people do not like having to download things to their computers or devices and Whereby is so easy to get connected with . I like that Zoom offers larger rooms, but at this point the cost is not worth the extra expense.

Google Voice should be also be use to those who have difficulty in speaking English. So the contract term will need to be a little strict as Google Voice is used in navigations as the part of GPRS navigation is personal. The private data need to be in control much more securely and safely.
