Interface ErrorInfoHeader

All Superinterfaces:

Cloneable, Header, Parameters, Serializable

All Known Implementing Classes:

ErrorInfo

public interface ErrorInfoHeader
extends Parameters, Header

The Error-Info header field provides a pointer to additional information about the error status response. SIP UACs have user interface capabilities ranging from pop-up windows and audio on PC softclients to audio-only on "black" phones or endpoints connected via gateways. Rather than forcing a server generating an error to choose between sending an error status code with a detailed reason phrase and playing an audio recording, the Error-Info header field allows both to be sent. The UAC then has the choice of which error indicator to render to the caller.

A UAC MAY treat a SIP or SIPS URI in an Error-Info header field as if it were a Contact in a redirect and generate a new INVITE, resulting in a recorded announcement session being established. A non-SIP URI MAY be rendered to the user.

Examples:
SIP/2.0 404 The number you have dialed is not in service
Error-Info: sip:not-in-service-recording@atlanta.com
