Twilio cannot send SIP trunking or domains calls using a specific IP address

Due to load balancing, redundancy, and regional restrictions, Twilio is unable to send all of your SIP traffic over a particular IP address. We recommend Elastic SIP Trunking customers allow ALL of our regional signaling and IP addresses for maximum compatibility.

You can find the full list of our SIP signaling and media IP addresses on the SIP Trunk Networking Information page in Console.
For further information to help you configure your infrastructure for your Twilio Elastic SIP Trunk, please see our SIP Trunking interconnection guides.
