Ok, I have a small officeserv system, the do not use an operator, they have the trunks ringing into about 8 stations on group 500. They have 4 trunks showing as lines 1-4 on the DS-5021 buttons, and several other buttons for stations. When a trunk rings, all the lamps for the stations listed in group 500 light up at the same time (because they are ringing). Is there a way to not have these lights light-up on the buttons of the phones when outside calls ring, The ringing trunk is flashing as it should be. The users are complaining that it is confusing when the phone rings and multiple lights are flashing. Any ideas? One other thing that might help is to have a different ringtone for outside calls vs station to station calls. But as I understand it, the ringtones are per station and the single ring for trunk calls, and double ring for station calls is fixed. Any ideas would be appreciated
