does duplicate station in cm do it? if not, in smgr, you might be able to edit cm endpoints, pick that one, and make a template of it.
I do seem to recall some bugs with SMGR in the later 6.3 stream or maybe 7.1.0 where it didn't like button modules on SIP stations and sometimes making any change to a station - like a name - via smgr - would nuke the button module.
