Media Streams IP Address Pool upcoming change

Effective November 16, 2023, Twilio will stop using the current IP pools for sending Media Streams’ media, and will begin sending Media Streams media from a broad range of publicly available AWS IPs, so that we can improve the flexibility, reliability, and scalability of our Voice products.

We’re giving advance notice to allow customers time to update your network infrastructure and applications, but before November 16, 2023, you must:

  1. Update your network infrastructure to stop allowlisting the old IP range used for U.S. Media Streams media:
       34.203.254.0/24
       3.235.111.128/25
       (Traffic is secure web socket over TCP)

  2. Configure your firewall rules to allow secure websocket connections (TCP port 443) to their websocket servers from any public IP address.

You should also configure your application to validate the X-Twilio-Signature header, to verify that the media stream is coming from an authentic Twilio source, as described here:  https://www.twilio.com/docs/usage/security#validating-requests

If customers do not update their network infrastructure, then forked media from Media Streams will not continue to be successfully delivered to your applications.

Toll-free verification API and Console now in Public Beta

Twilio’s self-service Toll-Free verification tooling is now in Public Beta. Customers who are looking to submit toll-free phone numbers for verification can now do so directly within Messaging Compliance API or Twilio Console without going through Support or Sales.

With Toll-Free verification tooling, you can:

  • Submit a new US or Canadian toll-free phone number for verification
  • Utilize customer profiles for a Toll-Free verification that were created in other compliance programs like A2P 10DLC, Shaken/Stir, etc
  • Get a list of toll-free verification records, including status and rejection reason (if rejected). Historical verifications submitted manually through CSV process are available for most toll-free numbers.
  • Re-submit a rejected verification (if rejection type is allowed to resubmit)
  • Subscribe to Event Stream’s webhook for toll-free verification events

Learn more about Toll-Free verification with Twilio docs:
