I have a 192 that i made so the customer can page two zones (A and B). I then added some new phones and put them in zone B but can't get them to page when I dial the short code. I have been through many of the memory blocks but can not find the differences. when the group B is paged line key 4 does light up but no page. Also i do not believe that it matters but all the new phones are from ports A1 to B2.
