600 Busy Everywhere Yes Yes
The IP Phone 1140E can send this

is set to NETWORK, and the user
chooses to ignore an incoming call.
When received, this response falls
through the default handling.

The IP Phone 1140E can send this
response when the user declines an
incoming call. An optional reason can
be supplied.

Default error handling
All 4xx/5xx/6xx responses (with the exception of 401/407) received by the
IP Phone 1140E 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 Phone 1140E
terminates the dialog.
If an in-dialog failure occurs during media (re)negotiation, the IP Phone
1140E falls back to previously negotiated media settings. When a failure
occurs that makes this impossible, the IP Phone 1140E attempts to clear
the call by terminating the dialog.
