November 21st – Wrong voice messages played

November 21th 8:00 AM – November 21st 07:00 PM UTC. An upgrade resulted in wrong voice messages played on calls to phone numbers.

This affected numbers connected to voice apps that had customized voice messages uploaded. Instead of the customized message, the default message, provided by Sonetel, was played.

We are working on improving our quality assurance processes to ensure that this does not happen again.
