Thanks for the reply... So our setup is as follow examples:

There are three groups, 5001, 5003 and 5005 for example.

There are two ring plans... ring plan 1 is night mode 00:00-23:59 all week
ring plan 2 is 07:00 to 19:00 monday through saturday with closed Sunday.

The problem is that groop 5005 has totally different hours of only 07:00-14:00 and sunday hours of 16:00-18:00.

I don't have a way to get group 5005 to have it's own special plan... as it tries to follow the ring plans 1 an 2...... any way around this?
