I have a new customer I just installed a MICS 6.0 it has a Valcom 3 zone page. Right now I press F62/1/2/3/4 for zones or all page that works O.K. what I would like to do is put all page(phones) and all page(external speakers)under a button. I do not want to put it on a co line.The valcoms 4 zones are areas 1,2,3 and then 4 for all page. can I program a button for f63 (to get the phones and loudspeakers) and then have them press 4 to get the 3 zones of the valcom ? Thanks
