While your business always aims for a high level of customer satisfaction, keeping up with consumer demands like fast support times, automated self-service, and personalized, authentic omnichannel communication is increasingly difficult.

This is especially true for businesses that either don’t have an in-house IT team, or that lack the time and knowledge required to build their own communication applications from scratch.

CPaaS (Communication Platform as a Service) Platforms like Avaya’s OneCloud CPaaS make it easy to meet customer demands for seamless support resolution and instant cross-channel conversation without having to recreate your entire communications infrastructure.

The Avaya OneCloud CPaaS solution leverages Artificial Intelligence, powerful APIs, and workflow management tools to optimize the omnichannel customer journey, empowering teams to create applications that are tailored to their specific markets, products, and services.

This article introduces Avaya OneCloud CPaaS along with its top features, pricing info, use cases, pros, cons, and alternatives.


What is Avaya OneCloud CPaaS?

Avaya OneCloud CPaaS is a development platform that allows users to build, access, and integrate diverse services, functions, and application APIs into pre-existing communication applications and tools.

By providing several pre-built communication platforms (like Avaya Spaces, Aura, Breeze, and Conferencing) and the building block REST APIs for DevOps teams, Avaya OneCloud CPaaS empowers companies to mix plug-and-play with ground-up design.

Users can pick and choose from Avaya’s pre-built platforms and communication API tools, avoiding paying for features and channels they don’t need.

Avaya OneCloud CPaaS serves as a solid foundation for application building and optimization, providing a customizable development platform that lets businesses fine-tune their own applications, ensuring they’re as “useful” to both teams and customers as possible.

In other words, OneCloud users don’t have to change their business processes or customer service strategies to meet the needs of existing software. Instead, they can create their own, automating and expediting workflows by integrating AI capabilities and data-driven automation.

OneCloud enables more effective communication across multiple channels, like:

  • SMS Text Messaging
  • Video Conferencing
  • Voice Calling
  • Email
  • Chatbots
  • Live Chat


Three Pathways To Your Avaya CPaaS Solution:

Here are the three primary pathway options to use Avaya’s CPaaS as a solution for your company’s needs.


1. Subscribe To A Pre-Built Solution 

Use pre-made entire applications built on CPaaS, such as IVR, Avaya Breeze, Spaces, Aura, or Conferencing, plugging the turnkey application directly into your infrastructure for immediate use: a website, webpage, CRM system, communication channel, or mobile application.

Since these applications are built on CPaaS, you can take parts of them (such as video conferencing from Spaces) and integrate them into other communication systems.


2. Avaya Builds Your Solution

If your company doesn’t have developers, Avaya’s Advanced Services team will work with you to build custom applications for your needs, ready for consumption in days.


3. Build Your Own Solution

Your company’s developers can use Avaya’s bank of REST APIs to create custom workflows that route communication avenues along customized paths, based on triggers and conditions baked into the workflow.


Avaya OneCloud CPaaS Top Features

Below, we’ll outline some of the important Avaya OneCloud CPaaS features.


Avaya Spaces

Avaya Spaces, developed on Avaya CPaaS, is a pre-built communication platform that allows a user to create a virtual communication and team collaboration space anywhere.

These Spaces combine a set of dynamic features in a single dashboard: voice, video conferencing, SMS texting, email, webchat, task assignment, and more.

Avaya Spaces


Creating a Space is easy– click “Create A Space,” give your space a name, and invite people from inside or outside the organization by name, email, phone number, web link, or even QR code.

Your Space’s dashboard organizes all the features you need, allowing users to access video conferences, chat messages, posts, task management, meetings, and more with one click.

Avaya Dashboard


Check out some of the other features and functionality in Avaya Spaces:

  • Project Flexibility: Once you create a Project Space, users can come and go, checking in on the space when needed to stay up-to-date, as Spaces saves everything with a two year automatic retention period
  • Large Meeting Capacity: A Space holds up to 1000 people, with a 61-participant HD view, so you feel like you’re in an office with your team. You can customize the video layout, choosing between auto, concert, grid, lecture, or panel views.

Avaya Video Call


During video conferences, an ongoing live chat allows participants to post documents, ask clarifying questions, use emojis, or raise a hand.

  • Meeting Scheduling: Use the Avaya Spaces Outlook add-on to schedule Spaces meetings directly from Microsoft Outlook, customize meeting details, set reminders for team members, determine meeting length and recurrence, share meeting notes, select meeting background, and invite team members
  • Rich Calling: Call participants directly from your browser using WebRTC, transfer, merge, or manage multiple calls
  • Artificial Intelligence: Noise elimination knocks out unwanted background sounds, background blur prevents your background from distracting other participants, and intelligent transcription and closed captioning recognize when there’s a new speaker
  • Security: Avaya Spaces meetings have over 30 significant security features, randomized non-guessable meeting IDs, unique private rooms where only authenticated users can enter, encrypted data, role-based control, and it’s all HIPAA and GDPR compliant

Users can also pick and choose their favorite Spaces components and integrate them into pre-existing communication channels.

For example, users can embed Spaces video conferencing into customer service platforms or on a tutoring website learning hub, or add the Spaces chat function to a contact center.

Spaces provides a CPaaS-supported whole platform, or toolbox, for you to build your communication system.



REST APIs are pieces of easily embeddable code for isolated communication functions–like talk-to-text conversion, voice transcription, or bulk messaging. These APIs individually plug into a company’s communication systems or larger communication applications.

Live Chat Avaya


Avaya CPaaS offers a wide variety of pre-formed APIs, organized based on the following general functional categories:

  • Calls
  • SMS
  • MMS
  • Conferences
  • Applications
  • SIP Registration and Domains
  • Recordings
  • Notifications
  • Transcriptions
  • Fraud Control

When building their own applications, users only need to select the REST APIs they want to add to their apps. These APIs give more capabilities to pre-existing projects or can be used to build an entirely new project, like an employee training hub.


Avaya SMS View


Avaya CPaaS provides a visual drag-and-drop interface to customize and map out API workflows.

For example, if you wanted a certain update on your website to trigger a mass SMS notification and post a message via chat within particular spaces, the visual workflow tool in CPaaS allows you to set up this path, using REST APIs.

Below, we’ve outlined some of the standout tools and commands that the Avaya REST APIs allow you to integrate into your communication channels:


Voice APIs and Integrations 

Below, we've outlined OneCloud's best Voice APIs.


Avaya Voice Call


  • Automatic Speech Recognition: Customers can navigate voice menus and IVRs by speaking their selection (in up to 26 languages)
  • SIP Registration: Connect your existing telephony infrastructure, including an IP PBX, to the cloud through Avaya
  • Embedded AI: Avaya CPaaS numbers can easily be associated to AI-enabled conversations with AI providers like Google Cloud, IBM Watson, and other Avaya-enabled AI partners
  • Text-to-Speech: Enable your app to convert written text into spoken voice (in up to 20 languages) that your readers will hear upon interaction with your webpage, app, or phone number
  • Audio Conferencing: Add voice conferencing to any app, enabling multiple parties to connect by calling the same number, while the host retains full control
  • Call Analytics: Avaya OneCloud CPaaS provides real-time analytics for every call, including tracking, billing, and caller background information

  • Other Voice APIs: Split Channel Call Recording, Caller Identity Management, Inbound Call Processing, and Call Tracking


Messaging APIs

Below are some of Avaya OneCloud's best messaging APIs.

    • Two-Way SMS: Receive text messages for free, from your purchased number, and only pay for outgoing text messages
    • Bulk Messaging: Send messages to mass groups of people, and receive real-time analytics detailing the delivery status of each SMS, so you can easily track the performance and success of messaging campaigns
    • Delivery Analytics: Allow mobile and web apps to support messaging, and gain access to analytics like response rate and open rate
    • Polling and Surveying: Gain useful insights with automated polls and surveys about customer attitudes and opinions
    • Custom Sender ID: Alter the sender ID of your SMS so that it appears as a local identity–with this service, multiple agents can contact customers from the same ID and number
    • AI Plus SMS and SMS: Apply toll-free and DID-enabled SMS and MMS to any AI-enabled conversation from AI providers like Google Cloud and IBM Watson
    • Other Messaging APIs: MMS, Automatic Long Texts Splitting, and Free Inbound Messaging

These tools allow you to scale and customize both your internal and external communication systems with ultimate control.


Mass Notifications

With Avaya Cloud Notification System (ACNS), part of OneCloud CPaaS, users can send timely outbound mass notifications through email, SMS, voice, web portal, or a combination of multiple channels.


Avaya Notification


When something important occurs–a parking lot at your university gets blocked off because of a gas leak, or a data failure brings down your company’s website–you need to be able to reach both customers and your team in moments. ACNS facilitates this.

ACNS’s functions, like geofencing and location tracking, allow you to notify audiences based on location, selecting only the particular audience you want. With two-way communication, customers or employees can respond to you for short back-and-forths, improving inter-company communication in remote settings.

The ACNS app makes it easy to organize customers and recipients into groups, and you can also provide customers the opportunity to opt into ACNS notifications with a self-submitted form.

ACNS allows you to add a question to your mass notification, which prompts a two-option response from customers–they respond 1 for a particular option, and 2 for another.


ACNS TExting


Here are a few useful functions within Mass Notifications:

  • Notifications to diverse endpoints: Notifications can reach enterprise desk phones, home phones, wireless phones, teletypewriters, and telecommunications devices for the deaf. Messages can travel through text, email, web, and social media, and can even be broadcast over speakers and horns.
  • Voicemail or answering machine detection: Automatically detect answering machines with the option to leave a voicemail
  • IP phone zone paging: Define zones of IP phones and broadcast audio or text messages, visible on the display screen and audible through the phone’s speakers
  • Integrated conferencing and collaboration: Allow key stakeholders to dial into an audio conference bridge for an impromptu conference
  • Detailed reporting: Summaries and detailed reports, available in the Web Portal, give real-time insight into who has been notified, and if and how and when they’ve responded


Business Phone Numbers

With Avaya CPaaS, users can buy local, toll-free numbers and use them fully online without any provisioning – just global coverage under a single carrier, with simple pricing.

Each number you buy is capable of implementing all voice, SMS/MMS APIs, meaning that you can use a purchased number to text mass notifications, and provide inbound-calling customers with menus and information via IVR to gain their information, or route them to an agent.


Avaya Phone Numbers


Here are some of the types of numbers and features included:

  • Shared Shortcodes: Lease pre-approved, instantly provisioned shortcodes to schedule SMS and MMS in bulk from a single, short, memorizable business number
  • Dedicated Shortcodes: Dedicate particular numbers to particular purposes by purchasing multiple numbers, schedule SMS and MMS functions from an individual number
  • Local Phone Numbers: Regardless of a business’s actual physical location, they can talk to customers with a phone number from a local area code
  • Toll-Free Numbers: Purchase toll-free numbers in over 40 countries for just $2 per month


Carrier Lookup Services

The Carrier Lookup API, within the REST APIs toolbox, is a standout feature that gives users insights about incoming calls based on the telephone number.

When an incoming call reaches your application, CPaaS can use Billing Name Address (BNA) and caller name (CNAM) lookup to provide you with the following information about the caller:

  • Phone type (mobile or landline)
  • Carrier network
  • Carrier ID
  • Calling location
  • Caller name

You can use this information to automate triggers, like responding to mobile calls with an SMS message linking to an immediate mobile experience using your website or webchat.


Avaya OneCloud CPaaS Plans and Pricing

Since Avaya OneCloud CPaaS offers such a wide range of individual APIs, turnkey experiences like Avaya Spaces, and the opportunity to build your own complete application with Avaya’s Services Team, there is no one-size-fits-all pricing plan–for a customized estimate, contact Avaya to set up a two-hour in-depth consultation, where a representative will provide you a detailed outline.

In general, however, with Avaya CPaaS you only pay for the services, APIs, and tools that you use. This means that you pay by the call, message, or number purchased.


Avaya Pricing


For each API tool used on top of a call or text, such as voice transcription or embedded surveys, you pay an additional charge–only for what you use.

Avaya OneCloud CPaaS Pros & Cons

Avaya CPaaS boasts a ton of positives, like flexible scalability along with the fact that companies can pick just the tools they want, to layer communication systems without having to purchase a whole new one.

However, integrating Avaya CPaaS’s REST APIs does require skilled developers, and if a company doesn’t have such a team, it may struggle to independently use many of Avaya’s tools and features.

Avaya OneCloud CPaaS Pros Avaya OneCloud CPaaS Cons
Easily scalable (up or down) Without developers, it can be challenging to implement the APIs
Maximum API flexibility: you can pick which APIs to use, individually or combined Difficult to buy just one API–buying one usually requires more for full functionality
Composability within pre-build platforms: Avaya Spaces, Aura, Breeze, Scopia Does not include the full Avaya Suite–Unified Communications, Contact Center, etc.
Avaya Advanced Services team will help you build your system Analytics KPIs within CPaaS are not as varied as in other platforms, like the Contact Center
Strong security (HIPAA compliant) across all channels The robust, plug-and-play API tools mainly apply to voice and text, not video or AI

One automotive retailer with over 200 locations faced a problem with communication: agents at each of their locations were using their personal mobile numbers, which gave the automotive company no visibility into the customer dialogue or contact information, and also didn’t give the automotive company a unified look in the customers’ eyes.

Leveraging Avaya Breeze, the automotive company worked with Avaya to create a two-way SMS application that enabled their existing landline numbers to deliver messages between sales reps and agents, while using a Salesforce integration to log the exchanges in CRM.


Professional Services

A home inspection services company, that connects homeowners with local home inspectors, was experiencing poor customer satisfaction due to long queues–agents were limited to phone calls in customer interactions.

This home inspection services company built a custom two-way SMS application using CPaaS APIs, allowing its agents to speak with customers and local inspectors in a single native app.
