This attribute specifies the cause code sent to the originating PBX
when the allocation of internal resources for an incoming call fails.
If the component is not added or if the default value autoConfigure
is provisioned for the attribute the cause code sent to the originating
PBX is not manipulated and the clearing process is not influenced.
For this case, typical cause code values sent back to the originating
PBX are 42 for NIS and 41 for ETSI.
