@AI Evy what are all the ip ranges that i need to whitelist that are invoked by the agent post chat webhook?

Thanks for tagging me @VI. I'll look through relevant sources and get back to you shortly.
### Answer Based on a Discord discussion about whitelisting for Retell AI, the following U.S. IP ranges were mentioned for firewall whitelisting: [(1) ]() -
143.223.88.0/21
-
161.115.160.0/19
However, I don't have documentation that specifically confirms these are the IP ranges used for post chat webhooks. The sources available discuss SIP/webhook traffic in general but don't explicitly detail IP ranges for chat agent webhooks specifically. For the most accurate and complete list of IP ranges to whitelist for webhooks, I'd recommend checking the official webhook documentation or reaching out for confirmation: Check out these potentially useful sources: - [List Chat Agents]() - [Contact Sales]() - [Retell AI GitHub]() Would you like me to provide a general answer based on what's available, or would you prefer to verify the specific IP ranges through official support channels?
