IP Addresses for Elastic SIP Trunking Services
Updated Migration Schedule: On 23 January 2024 Twilio will be updating the media IPs and port ranges for SIP calls in all regions to 168.86.128.0/18 and expanding the UDP port range to 10000-60000. Old IP and port ranges will no longer accept or send traffic after this date. Before this new migration date, we'll perform two days of testing with limited traffic. Learn more.
You MUST allow ALL of Twilio's following IP address ranges and ports on your firewall for SIP signaling and RTP media 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.
