/**
* 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:[email protected]
