z ReasonCode (E)
Reason codes are used by the gateway when it deletes a connection to inform the call
agent about the reason for deleting the connection. They may also be used in a
RestartInProgress command to inform the gateway of the reason of the restart. The
reason code is an integer.
Table 5-9 lists the defined values.
