Set SIP Headers

Using the Incoming Call component, it is possible to collect the UUI header that may be received on the incoming call coming from a SIP Trunk.

With the Set SIP Headers component, you can set a value to be sent on the User-to-User Information (UUI) SIP header when an outbound call is placed from that Studio Flow into a SIP Trunk.

The component can be used many times during a flow but it will override any value set in previous executions inside the same flow.

This data can include any custom information on the caller, such as location, or any call details that can be useful to route the call to the most appropriate agent.

Notes

• The values set on the Set SIP Headers component only be sent on calls placed from one of these components: Forward to External Number Component, Make Outbound Call, Request Callback from Queue, and Request Direct Callback.
• UUI can always be set but will only be applied on calls sent from Bring Your Own Carrier (BYOC) numbers and not for Public Switched Telephone Network (PSTN) numbers.
• The UUI will not be applied on agent-transferred calls and on forward to agent's external devices.
• The data’s maximum length is 256 bytes.
  The UUI data will be encoded according to RFC 7433.
