Quota increases for WebRTC Go GA

One year after launch, we are excited to announce quota increases for WebRTC Go to allow you to build, launch, and run 1:1 video applications for free, for longer. The changes are as follows: 

  1. WebRTC Go now comes with unlimited TURN usage, removing the previous 25 GB/month limit. 
  2. You can now scale up to 500 concurrent participants or rooms, up 500% from the previous limit of 100. 

To learn more about the quota increases and some of the key improvements we made for WebRTC Go developers over the last year, refer to the One year of WebRTC Go blog post.


Phone Numbers

Changes to the Emergency Calling API GA

Customers associating emergency addresses with their phone numbers don’t have to set EmergencyStatus to Active in the IncomingPhoneNumbers resource of the Phone Numbers API. Attempting to set the EmergencyStatus to Active or Inactive will be ignored, and will not have any effect on the enablement or disablement of emergency calling. 

When fetching an Incoming Phone Number, a new parameter EmergencyAddressStatus is returned with the registration status of the emergency address with the values registered, unregistered, pending-registration, pending-unregistration, registration-failure, and unregistration-failure.

Voice customers with US and Canada phone numbers should provide their accurate physical address to comply with the FCC and CRTC E911 rules. If you make a 911 call from a US or Canada phone number without a registered emergency address, Twilio will pass through a $75 fee per 911 call for the call to be delivered to a national emergency location center where a trained agent will ask for the emergency location.


For additional information, check our SIP Trunking and Programmable Voice documentation.


Programmable Messaging

WhatsApp Phone Number Migration is Generally Available GA

Businesses can now move their existing WhatsApp Business API phone numbers to the Twilio platform at any time whether they were previously registered through a different Business Solution Provider or directly with Facebook. Upon a successful migration, the transferred number retains its display name, messaging limit tier, quality rating, and Official Business Account status. High quality message templates on the account that it was previously registered on will also be copied over to the new account on Twilio.

A2P Brand Registration Secondary Fee Waiver Ended GA

This vetting costs $40 and was being covered by Twilio till Sept 30. The Secondary Vetting fee will now be passed through to customers and reflect in customer bills as the waiver has ended. 

Note Starter Brands and Starter Campaigns continue to remain free of charge.

Super SIM Billing Periods API Public Beta Beta

You can now read the current billing period for a Super SIM using the the new Billing Periods API allowing you to see when a Super SIM's current billing period started and will end. You can use this to determine when a Super SIM in ready state will automatically transition to active or when a Super SIM in active state will next be charged a monthly subscription fee.  Learn more about this new API, see the documentation.

Additionally, data usage towards a Super SIM's data limit is measured over its current billing period. You can leverage the start and end times indicated on a Super SIM's billing period and the Super SIM Usage Records API to determine how close a Super SIM is to hitting its data limit and when the usage towards the data limit will reset. To learn more about the steps to do this, check out this guide.
