Twilio has introduced a new feature for Twilio Elastic SIP Trunking that allows users to specify the geographic region where originating traffic is sent, which can lead to improved voice quality. This change enables users to direct calls over the Twilio Super Network to a specified region instead of the public internet, and can be achieved by including an optional region parameter in the origination SIP URI. The feature is available immediately, and Twilio offers instant provisioning with contract-free pricing, making it easier for enterprises to deploy SIP trunking quickly and at a lower cost.
