8x8 CPaaS vs Sinch vs Vonage vs Infobip: Australia and APAC Comparison

Choosing a CPaaS provider for Australia involves more than comparing SMS rates. Consider how well each provider supports local messaging requirements, verification, WhatsApp and other channels, APIs and integrations, fraud prevention, customer support and expansion into other APAC markets.

Four providers commonly considered for these requirements are 8×8 CPaaS, Sinch, Vonage and Infobip. All four offer programmable communications, but their product portfolios and strengths differ across messaging, voice, video, verification, omnichannel engagement and network intelligence.

For an Australia-based business, the right fit depends on your use case, target markets and technical requirements. Local deliverability, Sender ID compliance, channel availability, API capabilities, and APAC coverage can all affect the decision.

How Do I Compare CPaaS Providers in Australia?

Before comparing individual providers, look at the capabilities that will affect your actual communications workflows.

1. Messaging channels

Start with the channels your customers already use and the ones you expect to add.

For example, an Australian business may need SMS for transactional notifications and OTPs, WhatsApp for customer conversations, and voice as a fallback or escalation channel. An APAC expansion may also introduce channels such as LINE or Zalo.

2. OTP and verification

If you are using CPaaS for authentication, consider more than SMS OTP.

Look at:

• SMS, voice and WhatsApp verification
• Email and RCS verification where supported
• Silent authentication or data verification
• Flash Call
• Automatic channel fallback
• Number intelligence
• SIM-swap detection
• Traffic-pumping and SMS-fraud controls
• Verification analytics

3. Australia’s SMS Sender ID Register and compliance

Australia’s Sender ID requirements should be part of the initial vendor assessment, not something you address after choosing a provider. Under the Telecommunications (SMS Sender ID Register) Industry Standard 2025, ACMA’s SMS Sender ID Register becomes mandatory from 1 July 2026 – businesses that have not registered an alphanumeric Sender ID risk having their messages labelled “Unverified” to recipients. Commercial SMS also needs to meet the consent, identification and unsubscribe requirements of the Spam Act 2003, enforced by ACMA.

Check how each provider supports Sender ID registration, provisioning and troubleshooting, including who manages the registration process and what support is available if traffic is blocked or a Sender ID is not recognised.

4. APAC coverage

A provider’s global country count is useful, but it does not tell you everything about a specific APAC market.

For each country you plan to enter, check factors including SMS availability, local carrier connectivity, verification methods, and data and privacy requirements.

5. APIs, SDKs and integrations

Your technical team should assess the actual development experience, not just the number of APIs listed on a product page.

Look at API documentation, SDKs, webhooks, developer tools, integration options and how easily your existing applications and systems can connect to the provider.

6. Fraud prevention

For high-volume messaging and verification, fraud protection deserves its own assessment.

Ask providers how they detect and respond to threats like SMS pumping, SIM-swap risks, invalid or unreachable numbers, and suspicious traffic patterns.

7. Support and onboarding

A technically capable API is only part of the implementation.

For Australia and APAC deployments, ask about local support, account management, implementation assistance, escalation routes and service-level commitments.

Australia CPaaS Providers Compared: Services, Features and Security

1. 8×8 CPaaS

   

   8×8 CPaaS gives businesses a way to build programmable communications into their applications and customer journeys. Its offering covers SMS, voice, video, WhatsApp and other messaging channels, alongside verification, fraud protection and tools for managing customer conversations.

   For businesses in Australia, that means you can use 8×8 CPaaS for everything from transactional SMS and OTPs to two-way WhatsApp conversations and automated customer notifications. If you are expanding across APAC, the same platform can also support communications across multiple markets and channels.

    

   SMS and messaging APIs

   The 8×8 CPaaS SMS API lets you send SMS directly from your applications. You can use it for transactional messages, notifications, alerts, campaigns and other application-triggered communications.

   It also supports inbound SMS, allowing you to receive replies through a webhook rather than treating SMS as a one-way channel.

   This makes the SMS API useful when you need messaging to happen automatically, for example, sending an order update after a purchase or an OTP when a customer signs in.

    

   WhatsApp and omnichannel messaging

   Beyond SMS, 8×8 supports channels including WhatsApp, RCS, Viber, Zalo and LINE, with additional channels available through its broader communications products.

   WhatsApp can be used for both business messaging and customer conversations, while WhatsApp Business Calling is also available through Converse.

   This gives businesses more options when SMS is not the best channel for the interaction – whether that means sending a richer notification, continuing a customer conversation or giving customers another way to contact your team.

    

   OTP and user verification

   The 8×8 CPaaS Verification API is designed for applications that need to verify users during sign-ups, logins, account recovery or transactions.

   You can send verification codes through SMS, WhatsApp, Viber or voice, giving you different options when a customer does not receive or cannot use their first-choice channel.

   8×8 also supports Silent Mobile Authentication, which verifies eligible users through their mobile devices, helping reduce friction while strengthening authentication against risks such as phishing and account takeover.

    

   Voice and video

   8×8 also extends beyond messaging with programmable voice and video capabilities.

   Its voice API can support use cases such as programmable calls, virtual numbers, call flows and IVR. This can be useful when a customer journey needs more than a text message, for example, offering a voice fallback when an SMS OTP is not received.

   For video, Video Interaction allows a business to send an SMS invitation that opens a browser-based video session. Customers do not need to download a separate app, which can make video support easier to add to an existing customer journey. For businesses that need video embedded directly into their own app rather than opened from an SMS link, Jitsi as a Service (JaaS) offers a cloud-native video SDK that can be built into existing web and mobile experiences, with options like recording, RTMP streaming, and branded UI.

    

   Fraud protection

   

   8×8 CPaas takes a broad approach to protecting messaging, verification and identity workflows, with solutions covering different stages of the customer journey:

   • Omni Shield – Monitors messaging and verification traffic for suspicious patterns and helps detect and prevent fraud such as SMS pumping, toll fraud and artificially inflated traffic. During early-stage deployments, Omni Shield identified more than 85% of fraudulent SMS traffic while maintaining reliable message delivery for authorised communications.
   • Mobile Verification – Supports OTP generation and validation across SMS, voice and messaging channels, with Sender ID management, channel orchestration, automatic voice fallback and visibility into delivery, conversion and fraud performance.
   • Number Lookup– Provides real-time phone number insights, including validity, activity, carrier and location information, helping businesses improve routing, reduce failed attempts and avoid unnecessary messaging costs.
   • Descope CIAM – Adds authentication, authorisation and identity management within applications, with tools such as risk-based MFA, step-up authentication and passkeys to help businesses strengthen identity controls.

   Together, these solutions work to protect against fraud across the customer journey.

    

   8×8 Connect and 8×8 Converse

   These two platforms serve different parts of the communications workflow.

   8×8 Connect is a no-code platform focused on outbound campaigns. Teams can use it to manage messaging and voice campaigns, templates, services and reporting, while APIs and automation tools connect those communications to applications and customer journeys.

   

    

   8×8 Converse is focused on two-way conversations. It brings WhatsApp, SMS, voice, email, web chat and other channels into one workspace, allowing agents to manage two-way customer interactions without switching between separate tools.

   

    

   Developer support

   8×8 provides API documentation, developer resources and SDKs to support integrations across its communications services. Its APIs can be managed through 8×8 Connect, with tools for API keys, messaging and other programmable communications.

   In 2025, 8×8 CPaaS was named Best CPaaS Platform at the CX Awards, with judges highlighting its composability, embedded AI and ability to bring internal and external communications together on a modular platform.

   The following year, 8×8 was named a MetriStar Top Provider for CPaaS by Metrigy, and also received the Top Provider recognition for Contact Center as a Service (CCaaS). The company scored above average on both business success and customer sentiment, with particular strength in platform reliability and no-code and low-code application quality.

    

2. Sinch

   Sinch is a global communications platform offering APIs for messaging, verification, voice, video and email, alongside tools for customer engagement and contact centres.

   For businesses operating in Australia and expanding across APAC, Sinch covers use cases such as transactional SMS, OTP verification, customer notifications and two-way messaging.

    

   SMS and messaging APIs

   Sinch provides APIs for sending programmable messages, including SMS and other messaging channels. You can integrate messaging into applications for notifications, alerts, authentication and customer communications.

   For businesses that need more control over how messages are delivered, Sinch also provides connectivity and routing capabilities through its wider communications network. Sinch’s communications portfolio also extends into email, with separate products for no-code and code-heavy use.

    

   Conversation API

   Sinch Conversation API provides a single integration for communicating across multiple messaging channels. It supports SMS, RCS, WhatsApp, LINE, Telegram, Instagram, Facebook Messenger, Viber and other channels, with availability and capabilities varying by market.

   Instead of building a separate integration for every messaging channel, you can work with a common API structure and configure the channels you need.

   It supports both one-way and two-way messaging, making it useful for customer notifications, service, and engagement.

    

   Sinch Verify

   Sinch Verify is Sinch’s dedicated verification solution for businesses that need to confirm a user’s phone number during sign-ups, logins, account recovery and other authentication flows.

   It supports several verification methods, including SMS, voice, Flashcall and data verification, giving businesses alternatives when a standard SMS OTP is not the best fit.

   Sinch Verify also supports REST APIs and SDKs for iOS and Android, so developers can integrate verification into both web and mobile applications.

    

   Fraud protection

   Sinch provides authentication controls around its verification APIs to help prevent unauthorised verification requests from generating traffic. This is relevant to Artificial Inflation of Traffic (AIT), where fraudulent requests can drive up SMS or voice traffic and associated costs.

   Sinch also offers fraud and number intelligence capabilities across its broader communications portfolio, including tools designed to identify risks such as traffic pumping and SIM-swap activity.

   Developer support

   Sinch provides API documentation, SDKs and developer tools across messaging, verification, voice and other communications services. Its developer portal includes API references, guides and code samples to support implementation and testing.

   Voice and video APIs

   Beyond messaging, Vonage provides a programmable Voice API that lets businesses build calling into their applications, with Automatic Speech Recognition in 120 languages.

   Use cases can include automated calls, IVR, call control and other application-driven voice interactions. This can be useful when a customer journey needs a voice option alongside SMS or messaging.

   Vonage also provides a Video API for adding real-time video capabilities to applications.

   This feature supports video consultations, remote assistance, virtual appointments and other situations where customers need to interact with a person rather than simply receive a message.

    

   Vonage Verify

   Vonage Verify is the platform’s dedicated solution for phone number verification and two-factor authentication.

   It allows businesses to verify users through SMS, voice, WhatsApp, RCS, email and Silent Authentication, with workflows that determine which channels are used and in what order.

   Additionally, their Number Insight service can identify whether a number is valid, reachable, virtual or a landline, while SIM Swap Insight provides additional security by detecting if the SIM card linked to a given phone number has recently changed.

    

   Fraud protection

   Fraud prevention is built into Vonage Verify through Fraud Defender, which is designed to detect and block Artificially Inflated Traffic (AIT).

   Fraud Defender is included with Verify at no additional cost, providing customisable controls for different markets and accounts, and SMS burst protection, which caps the number of text messages sent to a specific country or destination within a short window, like 10 minutes, to stop fraud.

CPaaS Providers in Australia & APAC: Coverage & Support

If your Australian business is expanding across APAC, country coverage is only part of the picture when selecting a CPaaS provider. Local carrier relationships, channel availability, onboarding and support can all affect how easily you can launch and operate communications in each market.

1. 8×8 CPaaS

   8×8 CPaaS supports 160+ direct mobile network operators in more than 190 countries, with Singapore as its primary data centre, delivering reliable, low-latency performance across the entire region.

   Onboarding

   8×8 CPaaS has a dedicated Sender ID Self-Registration Module built into the 8×8 Connect Portal, designed to simplify Sender ID registration in regulated markets. Instead of handling registration through separate paperwork and email exchanges, businesses can submit and track applications through the portal.

   

   The module can automatically generate the required Letter of Authorisation (LOA) based on the registration details, while a central dashboard lets you track the status of Sender ID applications by destination country or Sender ID. The self-registration workflow currently supports markets including Indonesia, Thailand and the Philippines.

   Australia is not yet part of that self-registration workflow, so Australian businesses register and manage their own Sender ID directly with ACMA’s SMS Sender ID Register through their telco or provider. For Australian businesses expanding into Indonesia, Thailand or the Philippines, though, the module can make Sender ID onboarding more straightforward across those neighbouring APAC markets.

    

   Support

   8×8 offers a structured support model, tailored to meet the needs of small, growing, and enterprise-level businesses. Depending on the support tier, features include 24/7 availability, web and email support, and a line to a dedicated engineer. The highest support tiers offer a dedicated Customer Success Manager (CSM) and a Service Delivery Manager who oversees the day-to-day quality of your support experience.

    

2. Sinch

   Sinch’s Super Network has 600+ direct carrier connections and provides access to 190+ countries. Sinch also has an APAC presence, including its APAC headquarters in Singapore.

   Sinch provides an Alphanumeric Sender ID service, ensuring that your business stays compliant with the relevant regulations in Australia, Indonesia, and other APAC countries.

   Additionally, the company’s specialists can assist you in configuring your project using the Sinch Build Dashboard or Customer Dashboard. This includes setting up API applications, authenticating senders, and configuring key APAC channels like WhatsApp, Facebook Messenger, and SMS.

    

3. Vonage

   Vonage’s SMS API network spans over 1,600 direct-to-carrier and tier 1 connections globally, delivering high-reliability messaging across the Americas, Europe, APAC, and Africa.

   This provider has a developer-focused platform with API documentation, guides and code examples, making it well-suited to teams that want to prototype and build integrations themselves.

   Vonage’s support tiers range from Standard to Enterprise packages, encompassing an online knowledge base and standard communication channels, and expanding to include a Designated Support Engineer (DSE) and Customer Solutions Management (CSM) services.

   Vonage documents Australia’s Spam Act 2003 consent and Sender ID requirements and provides guidance on registering a compliant Sender ID for Australian traffic, including the process for having registered Sender IDs whitelisted with Vonage.

    

4. Infobip

   Infobip supports communications across 190+ countries, with 9,700+ global connections and 800+ direct operator connections. It also has a broad APAC presence, with offices across markets including Australia, China, India, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Thailand and Vietnam.

Key Takeaway

Each provider brings a slightly different focus to the CPaaS market, so the right fit depends on what matters most for your business:

• 8×8 CPaaS – Consider it if you’re looking for an Australia-focused option with transparent pricing, integrated communications and local support. It combines messaging, voice, video and verification capabilities, with tools designed to simplify onboarding and support communications across APAC markets.
• Sinch – Consider it if global messaging scale, carrier connectivity and verification are key priorities. Its broad communications platform covers messaging, verification, voice and other channels, making it suitable for businesses managing communications across multiple international markets.
• Vonage – Consider it if you’re building communications directly into applications and want a developer-focused platform. Its APIs cover messaging, voice, video and verification, giving development teams flexibility to build communications into existing products and customer journeys.
• Infobip – Consider it if you need a broader omnichannel platform that goes beyond communications APIs. Alongside messaging and verification, it brings customer engagement, data and orchestration capabilities into the same platform, which can be useful for larger customer communication programmes.

Ultimately, compare the providers based on your target markets, channels, integration requirements, support model and commercial terms, particularly if Australia or multiple APAC markets are part of your deployment.
