I am using the latest version of Panasonic's Programming Software. I can't figure out how to set the "Line Preference - Outgoing(Idle Line/No Line/Prime Line)". I've looked at all the parameters and I still can't figure out any in the programming software that will adjust this. I found out how to do it on the phones, but I can't see that the S/W wouldn't be able to adjust this setting.

Call pick up & out going CO line preferences
are set in station programming only, at the individual stations.

So there is no way to do this in the S/W programming?

No
