What IPs do I need to whitelist?

Depending on your location, and whether or not you have a firewall/acl configured on your network - you'll need to add both our media IP addresses and our SIP Signaling addresses to your Firewall whitelist configuration.

You can always find the updated list of addresses in https://sip.telnyx.com
