Sinch Maintenance - Elastic SIP Trunking - Revert Change for 603+ support Jun 18, 2026 23:15-23:30 UTC
Sinch Elastic SIP Trunking performed an emergency maintenance at 13:00 UTC June 18, 2026. This update has been reverted due to unforeseen circumstances. Support for 603+ will be rescheduled for a future date.
This change 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.
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/
