'ello all, and Hal especially, Howya been?

Just finished putting in a whole new system. New case Partner ACS R6, three 308's and a 012.

So far everything is perking along as advertised, except....

There are two stations with 6 button eurostyles on them, with three lines, the third line supposed to be the upper left button. Button no worky. Bottom two buttons intercom, just as advertised, next two up do the first two lines, top buttons don't do anything.

Plug in a 12 or 18 button phone, button works fine. Line not locked out, assigned to that ext. etc etc.

Ok, It's probably pretty obvious to the real phone techs out there, but what am I missing?

Thanks
