Many thanks for the suggestion, but the server comes back with the message,
rpm -e hylafax
error: removing these packages would break dependencies:
hylafax >= 4.1.5 is needed by dmc-mitel-hylafax-setup-4.1.5-1
So I tried your method with the dmc-mitel-hylafax-setup-4.1.5-1 on the end. Then ran your recommendation. Seems to have worked !
