Notice: Twilio SIP and Client Voice Media IP Pool Expansion (September 2019)

In Fall 2019, Twilio expanded our Media IP address ranges for the following regional gateways:

  • AU1 (Asia Pacific - Sydney)
  • BR1 (South America - Sao Paulo)
  • DE1 (Europe - Frankfurt)
  • JP1 (Asia Pacific - Tokyo)
  • SG1 (Asia Pacific - Singapore)

These Media IP changes affected all of our SIP Trunking, SIP Interface, and Client products, including the following:

  • Elastic SIP Trunking
  • Programmable Voice SIP Interfaces
  • Programmable Voice SDKs for iOS and Android
  • Twilio Client JS SDK

Notice: We recommend customers allow ALL of Twilio's signaling and media IP address ranges and ports on your firewall. This is important not only for users with phone numbers in different regions, but also for resiliency purposes.
