This is a product defect has been found in this CMS r16.3eg.f version which has been fixed in the CMS R16.3eg.g and higher version.
“This is related to an agent reconnecting to the caller before they complete a transfer. Code was put in place to handle this situation correctly in 16.3, however the call on hold did not have the hold properly stopped. This is what was causing the two hold times to be different.”
