turboDial users with corporate level local network management should provide their IT Support team with the information in this article. Firewalls that filter IP traffic based on IP addresses or ports must be checked to verify that Twilio’s addresses and ports are allowed.
turboDial users in small companies and work-at-home situations are far less likely to use a firewall that has blocked Twilio’s addresses or ports and do not need to take action unless specific problems with one-way voice and call drops are encountered.
What are the Requirements?
Twilio is making a change to the IP and port ranges for Voice products. Effective October 10, 2023, Twilio will update the media IPs and port ranges for calls in all regions. We’re moving from a per-region IP range allocation to a single global range (188.8.131.52/18).
Additionally, Twilio is expanding the media port range from 10000-20000 to 10000-60000. Old IP and port ranges will not accept or send traffic on October 10, 2023.
Before October 10, 2023, you must update your network infrastructure to allowlist the full IP and port ranges:
- IP range: 184.108.40.206/18
- UDP port range: 10000-60000
If you don’t make this update by this date, calls will experience one-way audio and will eventually be dropped. Old IP and port ranges will not accept or send traffic after October 10, 2023; however, you’ll need to keep them in your infrastructure until that date.Before October 10, 2023, you must update your network infrastructure to allowlist the full IP and port ranges:IP range: 220.127.116.11/18
