Release Notes

The voice GATHER feature allows our customers to build out voice solutions that listen for a response when a user is prompted to speak (e.g. “Say 1 to be routed to customer service, say 2 to be routed to sales”). This enables voice-centric interactions, like streamlined IVRs, to create more natural, self‑service experiences.

As our beta overview details, our WebRTC solution allows us to support both inbound and outbound voice, and leverage the full suite of Voice API features with improved call leg simplification. The EA release of our WebRTC solution also includes the addition of mobile SDKs for iOS and Android.

We’ve just expanded our services in South Africa to include emergency services. This now means we provide all necessary services in South Africa to provide full PSTN replacement connectivity. 

This release also means that we now have PSTN replacement coverage in 41 countries and territories!

This service is only available on our Universal Platform. If you’re not yet on our Universal Platform, please reach out to your Account Manager so they can help upgrade your account.

We’re excited to launch Dynamic Number Intelligence (DNI), Bandwidth’s newest package for advanced phone number data. DNI offers you a full suite of features, like carrier assignment for both voice and messaging, carrier deactivation reports, and the current observed activation status. We’ve added these high-tech upgrades to our Phone Number Lookup API and added real-time carrier info to our messaging webhooks, all for one easy flat rate.

These real-time signals can help maximize your mobile user experience, protect your sender reputation, and ensure every message reaches a valid, active destination.

DNI is available to all Bandwidth messaging customers and is priced as a fixed monthly rate based on your messaging volume, eliminating the per-lookup cost and making frequent list validation economically viable. For more information or to enable this tool on your account, please reach out to your Account Manager, or visit our product page on DNI for more information!

This launch allows our global customers to replicate the high-trust, unified identity strategies already proven in the US. By bringing voice and messaging together on a single local mobile identity, we’re enabling the seamless transitions between text and voice that modern AI experiences demand.

Available with the Gold Customer Success plan. Troubleshooting call issues just got a lot faster. Call Ladders give you a visual, step-by-step view of SIP signaling for any individual call — so you can see exactly where in the call flow something went wrong. PCAPs (packet captures) let you download the raw network traffic for that call and inspect it in your tool of choice. Together, they put the diagnostic power your engineers need directly in the portal — no support ticket required.

What’s new:

• View a SIP ladder diagram for any call directly in Call Logs
• Download a PCAP file for deeper packet-level analysis
• Quickly identify call setup failures, media issues, and carrier routing problems

Messaging Transfer Confirmation expands the functionality of Port-Out Notifications to cover internal hosting scenarios – i.e. when one customer attempts to host another customer’s messaging, the original customer can approve or deny the request. This helps prevent unexpected interruptions in messaging services.

The RCS Capabilities Lookup feature within Bandwidth’s TN Lookup API and Dynamic Number Intelligence enables customers to verify the RCS capabilities associated with the mobile endpoints they target, from high-level RCS Availability down to detailed RCS for Business feature support. With RCS Capabilities Lookup, customers can make a more informed decision as to which channel to leverage when messaging customers on their send list.

Eligible customers can now access agent provisioning within the Bandwidth App. This allows more customers to create and register RCS for Business agents, opening the gate for further adoption. Interested customers may reach out to their account manager to check eligibility.

Bandwidth has introduced Identity Authentication API, a pre-call API that gives enterprises verified control over how their outbound calls are identified to consumers. By authenticating call origins in the call flow before delivery, it prevents unauthorized brand display on mobile screens and restores consumer confidence in calls from your organization — directly improving answer rates and reducing reputational risk from spoofing.

Bandwidth has expanded Number Reputation Management (NRM) to support monitoring and remediation for a broader range of phone numbers – giving customers greater visibility and control over spam labelling across their entire calling footprint.

With this enhancement, customers can now add US phone numbers from their other Bandwidth accounts, including legacy or non-Unified Platform (UP) accounts, into their NRM account for spam monitoring and remediation.

In addition, NRM now supports non-Bandwidth US phone numbers. Customers can monitor and remediate carrier-flagged spam issues for numbers that are provisioned with other providers, helping protect brand trust and improve answer rates across all outbound calling.

This update ultimately enables customers to reduce reputation blind spots, proactively address spam labeling, and increase contact rates – regardless of where their numbers are hosted.

We have upgraded our WebRTC architecture to support inbound calling to WebRTC clients, and simplifying call legs when using Voice API features to create a better integration with our customers’ applications. This upgrade lays the foundation for a Voice WebRTC solution with greater flexibility than our In-App Calling experience today. This new architecture also improves the security model for WebRTC. The beta only supports a browser-based Java SDK.

Number Reputation Management (NRM) now supports monitoring and remediation for numbers that aren’t native to your Universal Platform account, including numbers on legacy Bandwidth accounts and non-Bandwidth US numbers. Start tracking and resolving improper call labels across your number inventory, to help boost answer rates and customer engagement. 

We’ve just expanded our services in Peru to include national and international outbound, portability, and emergency services. This now means we provide all necessary services in Peru to provide full PSTN replacement connectivity. 

This release also means that we now have PSTN replacement coverage in 40 countries and territories!

This service is only available on our Universal Platform. If you’re not yet on our Universal Platform, please reach out to your Account Manager so they can help upgrade your account.

The campaign verify token field (cvToken) has been added to the Toll Free Verification POST, PUT and GET endpoints. Please see our developer documentation for additional details. This is an optional endpoint intended for adding a token for political verification requests.

We are happy to announce that Customer Self Service for IP Whitelisting is now available. This capability allows you to add your termination and emergency services IPs to the whitelist yourself, without having to open a support ticket!

In order to streamline the process, we have introduced the ability for you to whitelist IP addresses yourself. Please follow the instructions in our support article to walk through this new process.

Effective August 1, 2025, we’re updating the MoveTns Order API to enhance the overall order experience and reduce the risk of service disruptions when moving phone numbers. This update introduces graceful handling of invalid numbers, along with protection for messaging services and 10DLC campaigns. For more information, check out our announcement.

We’re excited to announce the release of our new Zoom Contact Center integration on Bandwidth’s Universal Platform; designed to enhance the experience for customers leveraging Zoom’s Carrier Platform via Bring Your Own Carrier (BYOC). 

The Zoom Carrier Platform (Phone Provider Exchange and CCaaS) simplifies the choice of preferred PSTN provider partners for customers, supporting a rapidly growing global user base. This integration is a key part of Bandwidth’s Maestro offering, enabling seamless BYOC connectivity and supporting future onboarding or migrations for Bandwidth customers into Zoom. This initial integration supports North America (NA) and Europe regions. Additional regions will become available as we expand coverage on our Universal Platform.

We’ve improved how we track and report the status of your phone number import orders. When you import phone numbers for hosted messaging, you’ll now receive a clear breakdown of each number’s status:

• Success: Phone number was successfully added to your account.
• Failed: Phone number encountered issues during the import process.
• Processing: Phone number is still being processed.

We’re also now providing warnings and suggested actions for each phone number within your import orders to help you quickly identify and resolve any potential issues!

These updates give you better visibility into the status of your phone number orders, allowing for faster troubleshooting and reducing the amount of time you spend managing your phone numbers, making for a smooth phone number import experience.

You can review the updated API documentation for full details on the changes.

Effective May 29, 2025, Bandwidth offers STIR/SHAKEN Hosted Signing Service (HSS), which aids in complying with the FCC’s Third-Party Authentication Order’s call signing requirements, enabling you to sign your own calls with your own certificate without the need for in-house software or hardware. 

Using HSS, you can now easily load your STIR/SHAKEN certificate onto the Bandwidth platform and assign call attestation levels based on your own call signing policies. For more information or to sign up for HSS, check out our product tour or talk to a product expert.
