Upcoming changes to Twilio Interconnect SIP Signaling IP Addresses

Thu, 02 Jul 2026 00:00:00 -0400

In the second half of 2027, Twilio will update the SIP signaling IP addresses used for Programmable Voice SIP and Elastic SIP Trunking over Interconnect in all regions. The Interconnect signaling IPs, for both inbound and outbound SIP signaling over private connections, will move to the 159.26.160.0/20 range as part of infrastructure improvements for greater flexibility, reliability, and scalability.

Customers using these products over Interconnect will need to update their network firewalls to allowlist the new IP addresses before the cutover date. Depending on the specific Twilio solution in use, IP address configurations within that solution may also need to be updated.

SIP FQDNs/hostnames, TLS certificates, public internet SIP signaling IPs, and Media IP address ranges aren’t affected by this migration.

Voice Insights Call Summary: Removal of conference_participant field

Wed, 01 Jul 2026 03:00:00 -0400

The conference_participant field in the Voice Insights Call Summary is being removed from the REST API and Event Streams August 1, 2026. This field pre-dated Conference Insights and had limited accuracy due to the complexity of conference call flows. It is currently only populated for calls eligible to participate in a Twilio conference; all others return attributes: null. After removal, all calls will uniformly return attributes: null. Use the Conference Insights API or Conference Insights Event Streams for conference data going forward.

You can now send typing indicators across RCS, WhatsApp (WA), and Apple Messages for Business (AMB) using a streamlined consistent integration with JSON payloads.

Apple Messages for Business (Private Beta): Support for Typing indicators is available! Please note that AMB access is currently restricted as it is in private beta. How to use typing indicators on AMB is available in our beta documentation.

💡 Need more time? For longer workflows, you can send additional typing indicator requests to extend the duration before the default timeouts hit.

Conference list endpoint will default to in-progress conferences only on July 13, 2026

Wed, 10 Jun 2026 02:00:00 -0400

Starting July 13, 2026, the Conference list endpoint (GET /2010-04-01/Accounts/{AccountSid}/Conferences.json) will default to returning only in-progress conferences.

If you're querying for in-progress conferences (the most common use case), no action is needed.

Currently, calling this endpoint without a Status filter returns all conferences regardless of status (init, in-progress, and completed). This change is part of an infrastructure upgrade that separates in-progress and completed conference data into distinct systems, improving reliability and performance for real-time conference operations.

Data Residency for SMS (EU) is now Generally Available (GA)

Tue, 09 Jun 2026 19:00:00 -0400

The Programmable Messaging API is now generally available for SMS in Twilio’s Ireland (IE1) region. When using this feature, SMS message personal data is stored and processed in the EU up to the point it reaches Twilio’s connections with telecommunications providers.

With this release, the Ireland (IE1) region supports the following messaging features:

Programmable Messaging API: Send outbound SMS messages using phone numbers and alphanumeric sender IDs.
Inbound SMS: Receive inbound SMS messages via webhooks configured at the phone number or messaging service level.
Messaging Services: Manage IE1 sender pools from the Twilio console or via the API. Take advantage of Sticky Sender, Country Code Geomatch, Advanced Opt-Out, and service webhooks in IE1.
Messaging Logs and Insights: Analyze and troubleshoot IE1 SMS traffic in the Twilio Console.
Phone Numbers: Configure phone numbers for use in IE1 using the Twilio Console or the API.

To learn more and get started, see the developer documentation.

Upcoming cipher suite list update for all Twilio REST API endpoints on November 18, 2026

T-Mobile A2P 10DLC Daily Limit Warning Error Codes 30025, 30026, and 30027 Being Decommissioned

Tue, 12 May 2026 02:00:00 -0400

Starting May 21, 2026, T-Mobile A2P 10DLC daily message cap warning error codes 30025 (50% threshold), 30026 (70% threshold), and 30027 (100% of the daily limit) are being retired. These error codes will no longer fire in API error logs or webhooks, and the associated proactive warning emails will stop.

Error code 30023, which triggers when traffic hits 100% of the T-Mobile daily cap, is not affected by this change.

What do customers need to do?

Customers who have webhooks or monitoring configured for error codes 30025, 30026, or 30027 should plan to remove those integrations before May 21.

Customers who relied on these error codes or warning notifications to monitor daily usage can track T-Mobile message volume through Twilio Messaging Insights. Error code 30023 will continue to fire when traffic hits 100% of the T-Mobile daily cap, so customers can use that as a trigger for monitoring and alerting.

Conversation Relay Insights is now Generally Available (GA)

Wed, 06 May 2026 03:00:00 -0400

Conversation Relay Insights provides the observability to confidently build and scale your Voice AI agents. By analyzing end-to-end conversational signals—like latency, interruptions, and handling time—the dashboard highlights exactly where your agents excel at natural turn-taking and where friction may be emerging. This visibility allows teams to replicate high-performing interaction patterns, validate deployments, and systematically deliver more natural conversations.

For deep-dive troubleshooting, the call summary view allows you to inspect individual interactions with a synchronized event timeline and recording playback with visualized audio waveforms. This level of detail enables developers to reconstruct the exact flow of a conversation, pinpointing the bottlenecks that impact your customer's experience.

These features are available exclusively as part of Voice Insights Advanced Features.

Learn more in our Conversation Relay Insights documentation.
