IP Addresses for Elastic SIP Trunking Services

Global Media IP Gateways

Public Connections - Global Media IP Range

The Public Connections Destination IP Ranges and Port Ranges are now identical across all locations:

Secure Media (ICE/STUN/SRTP) Edge Locations	Protocol	Source IP	Source Port †	Destination IP Ranges	Destination Port Range
sydney (au1 ) sao-paulo (br1 ) dublin (ie1 ) frankfurt (de1 ) tokyo (jp1 ) singapore (sg1 ) ashburn (us1 ) umatilla (us2 ) roaming (gll )	UDP	ANY	ANY	168.86.128.0/18	10,000 - 60,000

† The SDK will select any available port from the ephemeral range. On most machines, this means the port range 1,024 to 65,535.

Regional Signaling IP Gateways

You MUST allow ALL of Twilio's following IP address ranges and ports on your firewall for SIP signaling traffic. This is important if you have Numbers in different edge locations and for resiliency purposes (e.g. if North America Virginia gateways are down, then North America Oregon gateways will be used). Twilio does not guarantee which edge location the media will egress from, without using the edge parameter since it can depend on which PSTN-SIP Gateway delivers the call to which Twilio edge location.

Please also note that these IP addresses are provided for firewall configuration purposes only and not all of these IP addresses will host active gateways at a given time. However, your SIP infrastructure should be prepared to accept signaling traffic from any of these IP addresses at all times. Customers should also avoid sending traffic directly to these IP addresses and instead use your configured termination Fully Qualified Domain Name (FQDN). Please see our SIP Trunking configuration docs for more details.
