I have a norstar mod ICS with a valcom V-2003A for paging. Everything works great but here is the problem. I have the phones programed with one button for paging using ftr 630, the problem is the Valcom needs you to pick a zone (1-3) or 4 for all zones to work. Any way to add that 4 (I want all zones) to the end of the feature code? Or a different way of programing, I want everyone to use just one buuton for paging all sets and the speakers.
