I received this email from Retell - I recevied this email from Retall - Dear Customer, As a follow-up to our earlier notice, please complete the steps below to ensure uninterrupted SIP connectivity during our upcoming telephony network update. If you use IP ACL for SIP Authentication Please ensure: All previously allowlisted Retell AI IP ranges remain in place. Add the new CIDR to your allowlist: 18.98.16.120/30 Your network firewalls also allow this CIDR. Your SIP trunking provider confirms IP-based authentication is configured correctly. Some providers (e.g., Telnyx) may require additional settings: If you use Credentials for SIP Authentication Please ensure: Your firewalls allow: 18.98.16.120/30 No further authentication changes are required. We appreciate your prompt attention to these configuration requirements. Retell Team I was wondering if there is a spot in Retell AI that we need to add that IP address to? We purchased the number through you so i'm not sure where to go about and update this.
