## Global SIP trunking — new signalling and media IPs

We're expanding the **Global** region with additional signalling and media infrastructure. New IPs must be allow-listed before the rollout on **May 21, 2026**.

> **Warning**
>
> This change affects **Global-region SIP trunking customers only**. US and EU regions are not affected.

### What you need to do

Update your firewall or ACL rules to include the new Global-region signalling and media IPs:

**New signalling IPs** (ports **32681** UDP/TCP, **32682** TLS):

* `34.75.151.191/32`
* `34.23.45.239/32`
* `35.231.28.238/32`

**New media IPs** (UDP **10000–60000**):

* `34.139.134.58`
* `34.73.14.16`
* `34.139.114.28`

See the [SIP trunking network guidelines](/sip-trunking-acl) page for the full updated allow-list, effective **May 21, 2026**.
