Example of how POM overrides the default SIP code to completion code mapping
If a customer does not answer the call and if POM receives UA_TemporarilyUnavailable (480), then by default POM disposes the record with the completion code Ring_No_Answer.
However, if you map the SIP code, UA_TemporarilyUnavailable (480) to a custom SIP type completion code, for example, CC_temp_unavailable, then upon receiving the SIP code UA_TemporarilyUnavailable (480), POM disposes the record with the completion code CC_temp_unavailable instead of Ring_No_Answer.
