When received, this response falls
through the default handling. See Default
error handling on page 233.

The IP Deskphone can send this

Default error handling
All 4xx/5xx/6xx responses (with the exception of 401/407) received by the IP Deskphone, when
attempting to initiate a call, result in the display of an error on the screen, and typically results in fast
or regular busy tone.
If a media negotiation fails during dialog setup, the IP Deskphone terminates the dialog.
If an in-dialog failure occurs during media (re)negotiation, the IP Deskphone falls back to previously-
negotiated media settings. When a failure occurs that makes this impossible, the IP Deskphone
attempts to clear the call by terminating the dialog.
