Elastic SIP Trunking IP Addresses and Connectivity Endpoints

Twilio's Elastic SIP Trunking is built with resiliency in mind, and as such, has SIP signaling and RTP media IP addresses in different regions around the world. This allows us to automatically fall over to different IP addresses or regions as needed, and helps ensure call deliverability. We recommend Elastic SIP Trunking customers add ALL of our regional signaling and IP addresses for maximum compatibility.
