[OpenSER-Users] transaction flags not visible in CANCEL

Hi Bogdan,
Flag inheritance by the replies works.
I did not know that it was not supposed to work for the CANCEL. It is
good to know because I was starting to loose my mind... Maybe a note
somewhere in the project's site would be useful. It is very strange
behaviour because t_check_trans() returns true which means that the
CANCEL belongs to an existing transaction, but the flags are not the
same as the original.
Last question: What about Re-INVITEs? The flags are not working there
either? If this is true, then the only way to save some information
about the transaction is to add it as a parameter in the contact? Or is
there some other way?
Thank you.
Best regards
George
