Changes from earlier releases and fixed issues
1. New Consultative Conference/Transfer behavior
a. If you select Consultative Conference, the system adds all parties to the conference through consultation
b. Supports switching between Consult call and existing call (from which consult conference/transfer is initiated)., However, if the switching between call is done, then the system replaces the Consultative/Complete Conference button with the Transfer button and enables the Add Work Item to conference option. It will no longer be a consult call after switching. Same behavior is applied for Consultative Transfer.
c. You cannot drag and drop from conference/transfer if call is in the consult state.
Details make sense for customer details provided working call from extension 12345. customer tried transferring it the old way and it did nothing (the transfer and conference buttons just never appear, you simply cannot drag it) so then customer transferred using the new way since the upgrade, by clicking very close to the green Hold icon and dragging and dropping. This was within the same call captured.
Per release note document provided for OneXa 2.5.10, it is working as design.
