The interval failed transfers post-dialog object is a metric
indicating the total number of failed transfers on second
and subsequent Customer Voice Portal transfers since system
start. After a SIP dialog is established, CVP performs SIP
transfers using re-INVITE messages. The object value does
not include rejections of SIP REFER transfers. The object
value does include failed transfers that were attempted after
a label was returned from the ICM within the CONNECT message
body.
