I have a 7400 with an SVMI-20E

I can't remember quite how this flows. One group overflows to another group:

SG 5010: (Main)
UCD
Distribute
Next Port 5020
Overflow 8
1: 165
2: 129
3: 104
etc

SG 5011: (Overflow)
UCD
Distribute
Next Port 5020
Overflow 1
1: 166
2: 130
etc

SG 5020 (Announcement)
Distribute
1: 3715 (Reserved VM Ports)
2: 3716
etc

UCD Group Options
5010
Group Index 10

5011
Group Index 11

Auto clear No

Is my overflow off, being that final destination on the first group is 5049 instead of 5011?

Total queue time is 210 seconds?

Is there also an option to have a system greeting say, "There are 3 calls ahead of you"?
