Action Required update to new IP range. Starting 26 September 2023 Twilio will be updating the media IPs and port ranges for SIP and Voice SDK calls in all regions to and expanding the UDP port range to 10000-60000. You will need to update your network infrastructure to ensure that you have whitelisted the full IP and port ranges before the migration completes on 10 October 2023. Old IP and port ranges will no longer accept or send traffic after this date but will need to be kept open in your infrastructure until that time. Failure to do so will result in one-way audio and dropped calls. Learn more
