Outbound Call Queue Insights in Programmable Voice REST API

Outbound calls made using the REST API are throttled and queued to never exceed the Calls Per Second (CPS) threshold value that is set up on the Account. This throttling may create undesirable behavior as call establishment may be delayed. With this release, a new attribute "QueueTime " is available to monitor the call queue time. Prior to this change, there was no indication into whether the outbound calls were being queued and delayed, which made it difficult to know when to update the CPS to an appropriate value. This change returns QueueTime with the value of the estimated call queuing time in milliseconds. This can be used to detect when CPS updates are needed.
