blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } Hi Rakesh, I think if T38FaxRateManagementis not received or received with value other than "transferredTCF", it is treated as protocol error and releases the call. Can you please let me know the entity that is releasing the call? Is the release from E/// core nodes? Regards Sampat
