See every variable on a call

Variables tab in Call Details with the filter, Collapse all and Copy as JSON controls, and the System group listing call_id and user_phone_number

If you’ve been piecing together what a call sent to your actions, open the new Variables tab in Call logs. It shows the value each variable had on that call:

System, pre-call, and collected variables, and inbound SIP headers
Every action’s inputs and outputs, including transfer SIP headers

Manage phone book entries via API

Once you added numbers to a phone book through the API, you could not read them back. You can now list a phone book’s entries, up to 100 per page, and update an entry by sending its new phone_number and transfer_condition.
