Important Service Update: Action Required for Deactivation File Service Jun 15, 2026 15:00-16:00 UTC
Dear Client,
As part of our commitment to improving service performance and reliability, we are announcing an important update to our Deactivation File Service.
To ensure your service continues without interruption, it is essential that you update your systems to use the new endpoint before the change date.
Summary of Changes
We are decommissioning the FQDNs listed below and replacing them with a new, unified endpoint. This update also includes several enhancements to the service.
To be Terminated:
ftp01.sinch.com
ftp01.clxnetworks.com
Replacement Endpoint:
deact.prod.sinch.com
IP Address: 184.169.203.194
Start Time
2026-06-15 15:00
Service Enhancements
The new endpoint introduces the following improvements:
Directory Structure: The Sprint directory has been removed, and a new Tier_2 directory has been added to house deactivation files from our tier 2 carrier connections.
File Naming Convention: The date in the file name will now reflect the day the service is run (e.g., deactivation_20250205.txt), rather than the previous day.
Expanded Data: Deactivation data from Verizon is now available through the new endpoint.
We recommend making these changes at your earliest convenience to ensure a seamless transition. Please let us know if you have any questions.

Sinch Scheduled Maintenance - Elastic SIP Trunking Jun 16, 2026 13:00-14:00 UTC
Sinch Elastic SIP Trunking will be deploying an emergency software update to add additional features and functionality. The purpose of this update is to add support of "603+" which a newer SIP response code used in U.S. voice networks to signal that a call was blocked by the network, usually because it was identified as likely illegal, fraudulent, or unwanted traffic.
The scheduled work is not expected to impact services. This is being sent as a courtesy notice in the event that you experience issues with your service during the maintenance window.
For information about our product enhancements, we encourage you subscribe to our Elastic SIP Trunking Release Notes posted in the Sinch Community at: https://community.sinch.com/
