About User to User Information (UUI)
PureCloud’s User to User Information (UUI) support allows you to send data along with outbound calls as well as receive data from inbound calls. PureCloud adheres to the IETF UUI specification for UUI data.
The PureCloud UUI feature applies to both inbound and outbound calls.
The PureCloud UUI design automatically makes inbound UUI available to IVR flow and Script authors by using a system variable that contains the content of the UUI.
To send UUI data requires some trunk configuration to specify the header name and determine whether to send the the UUI data dynamically or statically.
