GA Twilio SendGrid Platform

Twilio SendGrid Releases Domain Connect Support for GoDaddy

Twilio SendGrid has launched support for Domain Connect with GoDaddy to improve the Domain Authentication process. The updated Twilio SendGrid user interface eliminates the need to manually copy and paste CNAME records from Twilio SendGrid to GoDaddy, allowing you to onboard more quickly and start sending mail. Customers are now able to click a button and sign into their GoDaddy accounts from within the SendGrid platform. Twilio SendGrid will then authenticate their domains automatically by making the necessary DNS entries for them.

There are no other changes to existing capabilities. No action is required for customers at this time.

Twilio Functions is adding support for Node.js v16

We are keeping your runtime up to date in accordance with industry standards. Based on the Node.js support schedule, Node.js v14 will no longer be in Maintenance long-term support (LTS) status after April 30, 2023. Production applications should only use releases of Node.js that are Active LTS or Maintenance LTS.

Your currently deployed functions will continue to execute on the existing Node.js v14 runtime if no changes are made.

Follow these instructions to upgrade, test, and deploy your code and ensure a safe transition to Node.js v16.

Upcoming changes to Twilio Voice Media IP Addresses

In 2H 2023 Twilio will be updating the media IPs and port ranges for Elastic SIP Trunking calls in all regions. We will be moving from a per-region IP range allocation to a single global range; 168.86.128.0/18. Additionally, we will be expanding the media port range from 10000-20000, to 1024-65535.

We are making this change to provide flexibility, reliability, and scalability. There is no action required at this time, and we will provide a more precise timeline approximately six months before the change. At that time you will need to update your network infrastructure to ensure that you have whitelisted the full IP and port ranges. Failure to do so will result in one-way audio and dropped calls.

Upcoming changes to withheld caller ID behavior for <Dial> calls

Twilio is changing how we persist caller ID information for <Dial> calls where the inbound caller ID is withheld; e.g. ANONYMOUS, RESTRICTED, etc. Today Programmable Voice translates the alpha string into digits. This behavior will change and we will begin to persist the alpha string from the inbound call to the outbound <Dial> leg for calls where the caller ID is withheld by the calling party.

This represents a significant change in the behavior of our APIs and developers will need to ensure that their systems can gracefully handle alpha characters in the To and From fields for requests and responses to the /Calls API, in TwiML,webhooks, and in status callbacks.

If the callerId parameter is used with the <Dial> verb, the outbound caller ID will reflect what was provided with callerId, regardless of the caller ID on the inbound call.

Upcoming changes to Twilio Voice Media IP Addresses

In 2H 2023 Twilio will be updating the media IPs and port ranges for Frontline calls in all regions. We will be moving from a per-region IP range allocation to a single global range; 168.86.128.0/18. Additionally, we will be expanding the media port range from 10000-20000, to 1024-65535.

We are making this change to provide flexibility, reliability, and scalability. There is no action required at this time, and we will provide a more precise timeline approximately six months before the change. At that time you may need to update your internal network infrastructure to ensure that you have whitelisted the full IP and port ranges. Failure to do so could result in one-way audio and dropped calls.
