Whitelisting Telnyx IP Addresses

We will explain what Telnyx IP Addresses you will need to whitelist to ensure your service works properly. See Telnyx guidance and requirements.

Whitelisting Telnyx IP Addresses

To ensure optimal performance of your Telnyx services, please whitelist the following IP addresses by region and purpose.

SIP Signaling and Media Servers

If your network uses a firewall or ACL, add both our media and SIP signaling IP addresses to your firewall’s whitelist.

For the most up-to-date IP addresses, refer to: Telnyx IP Addresses.

Webhooks

Telnyx programmable services, including TeXML, Fax, Messaging, and Call Control, deliver webhooks from the following regional IPs.
