    The Avaya [One Cloud CPaaS (formerly Zang Cloud)] of course is very well suited for any business purpose where the automated sending or handing of SMS and voice conversations, but specifically being able to use the embedded "Voice Input" functionality allows you to combine Avaya CPaaS with Natural Language and AI with these multi channel inputs which brings the customer experience to another level!

    In terms of service quality, I will conveniently recommend Twilio to colleagues without an hesitation. The only reason why I may not recommend Twilio will be because there are cheaper alternatives out there. For me and my marketing department, our relationship with Twilio's services is primarily around quick, reliable delivery of marketing content to prospects , leads and customers. I dare to say that over the last six years ,I have seen Twilio do this exceptionally well without problems.

    • 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
    Discontinued Products
    Avaya OneCloud CPaaS and Spaces Learning make it easy for learners, coaches, and teachers to connect with each other – providing an engaging and effective learning experience. The intuitive user experience, natural collaboration environment, and real-time communications tools empower virtual education that is simple, hybrid, and interactive. Imagine a day-in-the-life of Mark Rowland, a home-based customer service adviser at a large telecommunications company. Mark was recently scheduled for some customer support training, based on identified gaps in his job performance. Mark starts on the “My Classes” screen. The home page for each topic includes a live feed of announcements, learning-related posts, and other activity. The People panel displays a list of all participants and provides an indication of who is currently online. Mark clicks the ‘Join Virtual Classroom’ button to join the next Virtual Coaching Session. Mark meets with a coach and several peers in a live video collaboration environment. Next, Mark clicks the Chat tab and quickly says hi to the group. The coach shares his screen and begins walking the learners through the latest internet connection process for broadband routers. Afterwards, Mark notices that a recording of the session is now available in the Stream.

    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.

    I have always found Twilio to be reliable platform. I'm not a huge fan of the new home layout but I'm sure they changed it for a reason, and I can still find my way around. It's a very dependable platform.

    Avaya OneCloud CPaaS support has been excellent. Specifically:
    • Onboarding new users (licensing)
    • API integration support
    • Client platform support for learners
    • Seamless rollout of new features (and documentation)

    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.

    We have tried many other CPaaS platforms including Twilio, Telnyx, Nexmo, SignalWire and Bandwidth. The Avaya CPaaS has the richest set of available features combined with the most competitive pricing model!

    Twilio is the idea solution for our needs, which involves sending targeted SMS messages to prospects who have opted into our ads. We do this to communicate offers/services and also to remind prospects in the lead-up to sales appointments (plus post-meeting communications). We have just started using WhatsApp, and this could be a very useful tool for community building and may compete with Twilio over time.

    • 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
