Twilio Changelog

This release contains a significant update to the Network Bandwidth Profile API for multi-party applications. It provides two new settings to manage video track switch on/off and video resolution selection. The update is available on JavaScript, iOS and Android SDKs.

This enhancement allows for more efficient use of bandwidth and CPU in multi-party applications, which translates into a higher quality video experience for end users. It can dynamically tailor the incoming video tracks to match the active UI layout. In addition, it provides developers with more fine grained control over the video tracks to allow developers to create unique user interfaces while still being efficient with bandwidth and CPU.

For more information on this update, see our blog post here or review the documentation here.

In some cases calls placed using the advanced SIP features <Refer>, and <Dial><Sip> Multidial are not being properly billed for Voice Insights Advanced Features usage. We have introduced a fix that will result in these call flows being billed properly.

A2P 10DLC brand and campaign registration for all 501(c) nonprofit organizations is now available as part of Twilio’s A2P 10DLC Console and ISV API onboarding experience.Nonprofit organizations can register using the Charity / 501(c)(3), Political, or Standard use cases depending on their entity type:

• 501(c)(3) organizations should register campaigns with the Charity / 501(c)(3) special use case. Charity / 501(c)(3) is a reserved use case for 501(c)(3)s to receive discounts on A2P carrier fees.
• 501(c)(4), 501(c)(5), and 501(c)(6) organizations sending messages that are political in nature should register with the Political special use case, or register non-political messaging with standard campaign use cases. The Political use case receives increased messaging throughput on A2P.
• All other 501(c) designations should register their campaigns with standard campaign use cases.

For more details on the Charity / 501(c)(3) and Political campaign use cases, please see this support article on special use cases.

Note: We're still working to enable registration for 527 Political organizations and for the Emergency Special use case.

This release features the creation of the Elastic SIP Trunking Pricing API. Use this API to query a list of countries with pricing available and the origination and termination trunking prices for a particular country with the Trunking Country subresource. Additionally, query for phone number prices for a particular country, or the price for originating from a particular Twilio phone number to any destination number with the Trunking Number subresource. Prices returned will be specific to your account.

On November 1, 2021, Twilio will discontinue support for the 2008 Calls API. Customers who are still using this interface after it’s been discontinued may receive error responses. This change was previously communicated via email to customers with 2008 API usage on December 7, 2020 and April 24, 2021.

Please follow these migration guidelines to update your code from the 2008 API to the 2010 API.

Messaging Customers are required by U.S. carriers to register for A2P 10DLC. Independent Software Vendors that offer other customers the ability send SMS and MMS need to register themselves as an ISV brand via Trust Hub in the Twilio console and then they can register each customer as a Standard Brand or a Starter Brand. Registered Brands can then register use case campaigns.

Starter Brand registration is now available for all independent software vendor (ISV) customers to register your customers for US 10DLC compliance and send SMS and MMS in the US with 10-digit long codes. Starter Brand registration is intended for customers who send fewer than 3,000 daily SMS segments and MMS messages over 10-digit long codes AND use five or fewer 10-digit U.S. long codes. Twilio is covering the costs for Starter Brand registration and monthly campaign fees.

ISV Customers can read the Starter Brand overview and step-by-step API walkthrough as they prepare to register their customers.

Version 2 of the Twilio SendGrid Segmentation API is now in Public Beta. Based on Structured Query Language (SQL), this API unlocks new segmentation use cases such as segmentation on multiple engagement events and segmentation on NOT events.

See the Segmentation v2 API documentation for examples of what's possible with this new API.

Voice Insights Call Events and Call Metrics are now available on Event Streams, in addition to Call Summary which was already available. Developers can now subscribe to these Voice Insights events and have them delivered to their preferred destination through Event Streams.
