Twilio Changelog

Voice Insights Dashboard can now be filtered by call direction and edge location.

Direction filtering allows you to compare call behavior between different call flows. For example, you can now investigate differences in network performance between Trunking Originating or Trunking Terminating calls.

Media region filtering has been available for some time, but we have updated the labeling to reflect the new Edge Location format; e.g. Ashburn (us1).

With Twilio Functions invocations moving to General Availability, you now have guaranteed service level agreements for functions and assets that you invoke. Twilio Functions replaces the need to host or stand up your own web server to serve TwiML or any other HTTP responses, underpinned by your own infrastructure and programming logic. Functions gives you the ability to develop programmatic logic to handle the orchestration of discrete tasks with the convenience of pre-built cloud infrastructure.

You can now perform inbox rendering tests across new devices and inbox providers. Inbox rendering tests help you ensure that your emails are displaying as intended across your customers’ preferred device types and inbox providers.

Customers can now view the time taken by Twilio to process their messages via the Latency report visible in the Programmable Messaging Insights console.

Message latency is calculated as "Time Twilio sent the message - Time customer made message request API call." Customers can also view the limits applied to their individual senders, messaging services, and accounts via Modals in the Insights report.

This blog contains details about the product and this new guide explains how applications can be built to handle scale from the beginning.

The Plugins Dashboard now displays all legacy plugins currently enabled for your agents. With this feature, the Plugins Dashboard is the source of truth for all plugin information in Flex. This makes it easier for admins to track the migration of their legacy plugins to the latest Plugins API. Admins can access the Plugins Dashboard via the Admin UI.

You can now bulk delete Automations using the multi-select tool from the Automation homepage.

To select one or more Automations to delete, click the checkbox to the left of the Automation. Next, open the Selected dropdown and then click Delete.

Programmable Voice SIP Registration has been updated to allow SIP Endpoints to be registered to Twilio via all of Twilio’s Edge Locations globally. Previously, all SIP endpoints were required to register to the US1/Ashburn edge.

The format for the Edge-specific domains is now as follows:

{domain-name}.sip.{edge-location}.twilio.com

You should typically have your SIP devices register and send SIP messages via the Edge Locations closest to their physical location.

When sending a call to a registered SIP endpoint it is no longer necessary to include the edge location in the URI. Twilio's backend infrastructure knows which edge location the endpoint has registered on and will automatically route the traffic to the appropriate destination. The new URI format for calls to registered SIP endpoints is:

{domain-name}.sip.twilio.com

This change will not affect SIP endpoints using the previous method, i.e., endpoints registered using the US1/Ashburn edge will still work using the previous format.

Learn more in our blog post, or see the SIP Registration documentation for more details.

You can now add any reserved field or custom fields to a signup form. This means marketers can capture more of the data that they rely on when contacts sign up via a signup form.This means marketers can capture more of the data that they rely on when contacts sign up via a signup form. The collected data will then flow directly into Contacts within Marketing Campaigns.

Programmable Voice SIP interface now supports Inbound SIP REFER to Twilio. When an inbound SIP REFER message is received on a SIP call initiated using the TwiML <Dial> verb, Twilio accepts the REFER message and generates a webhook to customer application. This allows customers to initiate call transfers from their SIP devices. Please see the SIP REFER-to-Twilio documentation for more details.

In addition, Programmable Voice SIP interface now supports multidial to <Sip> endpoints, allowing you to dial up to 10 different <Sip> endpoints using the TwiML <Dial> verb, prior to this release TwiML <Dial> only supported multidial on <Number>, or <Client>.

Learn more in our blog post, or see the SIP Multidial documentation for more details.

Emergency Calling is now generally available in the United Kingdom for Elastic SIP Trunking. Customers are now able to make Emergency Calls from their Twilio United Kingdom local phone numbers that are capable of emergency calling using Elastic SIP Trunking with the Twilio platform, which will route emergency calls to the appropriate Public Safety Answering Point (PSAP) and pass along the corresponding emergency address.
