Additional Signaling Endpoints Mar 9, 2026 19:00 - Mar 10, 2026 19:00 CDT
To continuously improve our service and platform resiliency, we will be deploying additional signaling redundancy in the Eastern United States on or after March 9th, 2026.
If you self-host your phone system and enforce strict traffic blocking or Geo-blocking, action is required.
To prevent service disruptions with your SIP devices (PBX, ATA, etc.) and ensure a seamless transition, please verify that your PBX network configuration includes our new signaling and media IP range (216.52.108.0/22) in your firewall rules and/or local ACL’s.
For a complete list of our IP addresses, please visit our developer documentation:

Please do not hesitate to contact support via ticket if you have questions or concerns. You can create a ticket on our Portal.
