An issue with the Voice products in our US data center occurred between 13:05 and 13:13 UTC on 6th February 2019. The issue caused all new outbound Voice API calls to fail, as well as inbound SIP calls. This did not affect outbound SIP or Verify products.
All services have been restored. Please contact email@example.com
if you continue to experience problems.
A post-mortem will be published in the next few days.
