Effective July 1, 2022, a tone detection enhancement to our Answering Machine Detection (AMD) feature will be available. This will enable the application to detect answering machine tones, thus allowing the application to better time when to leave a message. 

This will be enabled for all accounts on October 1, 2022. Customers can contact their account manager or customer service manager if they would like it to be enabled before October 1. There is no additional charge for tone detection.

The tone detection addition will indicate a tone by returning a new machineDetectionResult value of “tone-detected” in machineDetectionComplete webhook. This value will only be returned if Answering Machine Detection is invoked with delayResult set to true.

We have introduced a new call modification endpoint that makes it easier for customers to pass BXML on an active call by directly calling the new API endpoint with the new BXML.

For more information, check out our API docs on how to Modify Calls with BXML or our guide on how to Modify Calls in Progress.

Starting June 23, 2022, Bandwidth is offering customers the ability to view telephone numbers prior to purchase through an advanced search in the Global Portal API. For more information, view our API docs.

Beginning July 15, 2022, Bandwidth is requiring Voxbone Portal users to explicitly select user privileges within sub-accounts to continue API accessIn order for sub-accounts to be able to continue making API calls to these endpoints, users will need to have the following privileges set via the Voxbone Portal:

/configuration  – “Configuration” privilege required

/regulation – “Regulation” privilege required

/inventory  – “Ordering” or “Configuration” privilege required

/ordering – “Ordering” privilege required

Bandwidth is enabling Outbound Call Queueing for Voice API customers on April 30, 2022.

Before, if customers exceeded their calls per second (CPS) rate, any calls over that limit were rejected. Instead of rejecting those calls, Outbound Call Queueing places them into a queue to be completed based on the customer’s CPS limits.

Beginning February 7, 2022, we’re updating message search API so that users receive 429 error codes when rate limits are exceeded.

Bandwidth has released an Answering Machine Detection feature for our V2 Voice Platform. You can now see if a call is answered by a person or was sent to Voicemail.

This enhancement to your Voice API experience will allow for better use of automated call routing. It will also be helpful as your teams design workflows and processes that are directly impacted by who’s answering the phone.

Please contact your sales account manager to contract for Answering Machine Detection.

What’s happening? The Full Phone Number Details report now includes the associated Campaign ID. Customers can use this information to validate that their 10DLC numbers are properly associated with their registered campaigns.

What do I need to do? You don’t need to take any action. The report is available for use.

Short Code (SC) SMS messages destined to US Cellular are now split out into multiple single-segment messages.

Multi-segmented SC SMS messages to US Cellular are now being split up into multiple single-segment messages, resulting in customers receiving multiple Delivery Receipts (DLR).

Prior to this fix, multi-segment messages to US Cellular were failing due to a limitation in their handling User Data Headers (UDH). This fix means that multiple single-segment messages will have their own DLR.

Customers will receive multiple DLRs unless suppression is implemented.

Voice API customers now the ability to use SIP clients directly with our Voice API platform. Customers can provision domains and user credentials to be used with their SIP clients so they can be called using a SIP URI like [email protected]. Customers can now have 10 active registrations for a specific user that can make or receive calls. Contact your sales account manager if you are interested in learning more about this feature.

Bandwidth has released the ability for V2 MMS customers to specify a “filename” when sending script file media. The “filename” can be specified in the standard Content-Disposition header of a V2 MMS message.

We are excited to be launching v3 of our WebRTC platform. This update includes:

• Upgrades to our media server infrastructure which will provide improved video and audio quality
• Improved scaling performance
• Transition to the WebRTC Unified Plan SDP format which will provide better support for Firefox and avoid the impact of Chrome’s removal of support for the deprecated Plan B format.

We’ve made it very easy to bring your WebRTC browser side application up to date: all you need to do is update your browser side SDK to the latest version (0.9.x) by August 1st, 2021.

This SDK maintains compatibility with the recent versions of the browser SDK, so none of your JavaScript code needs to be changed. We will be following up with a more detailed email notice to contracted customers.

• A slight change to the way that you log into the Bandwidth App. First you will enter your username, then another field will appear to enter your password.
• API user credentials will no longer be able to access the Bandwidth App via a web browser and will only be able to authenticate via the API. Read our support article.
