I have updated orthanc to the latest 1.9.7 where the feature alwaysallowmove is true in configuration file however if I use C-move protocol in my dicom viewer without putting that in dicommodality it will not do C-move
For C-MOVE to succeed, Orthanc must know where it must send its data to, which necessitates the definition of the target modality in the “DicomModalities” configuration option. This is explained in the Orthanc Book:
https://book.orthanc-server.com/dicom-guide.html#dicom-move
The “AlwaysAllowMove” option only controls what modality can issue a C-MOVE request (cf. the “ISSUER” in the figure of the Orthanc Book).
