UUI SIP Header

Defines the value to be sent on the UUI header, and can be built using free text or variables from which the value will be included.
The UUI standard SIP header is typically used to carry short pieces of information that are relevant to be shown to users receiving a given call, or that may inform a target system to better route the call to the appropriate team or user.

Example use cases:

• Having a call being handled by Auto Pilot that, when escalated, may need to be routed to an external system and should include context on UUI about the subject or call identifier to ensure that the target system can better route it.
• Building a Studio flow that collects the customer tax number and uses it to check if the customer is a subscriber. If not, route the call to another system but include the tax number collected in the UUI header so that it is visible to the user on the target system, to avoid asking for it again.

• The UUI will not be applied on agent transferred calls, on forward to agent external devices, on Make outbound call component or callbacks.
• The data’s maximum length is 256 bytes.
• The UUI data will be encoded according to RFC 7433.
