I have the following groups:
500 - Overflow (32 members) - next port 511 - (Same members as 506)
501 - Reception (1 member) - will be operator
502 - Small side company (4 members)
503 - Compliance group (5 members)
504 - Client Services (17 members)
505 - Accounting (7 members)
506 - Recruitment group 1 (32 members) - Next port 511
507 - Special recruitment group (4 members)
508 - IT (3 members)
509 - Housing (2 members)
510 - HR (1 member)
511 - Recruiting group 2 (30 members)

The reason I chose to have 5 call buttons and 5 or 6 GPIK buttons is that we have a large amount of recruiters here that deal all day long on the phone. 90% of our calls are done by the extensions in 506 and 511 (No overlap of extensions between those groups)

For example, I have seen 3 calls come in at the same time. So, I figured more call buttons would allow quicker response, especially around our peak inbound times (10am cst and 2pm cst).
The reason for the GPIK buttons is some managers want the ability to see where calls are coming in and answer calls if they ring too long. But are you saying that the GPIK will only work for the groups you are a member of? I have multiple GPIK buttons on my phone. They flash red when calls hit those groups. I guess I never tried picking up a call in a group.

As far as BARGE, I have 3 levels setup:
1 - SECURE = NO, OVERRIDE = NO - Regular employees.
2 - SECURE = NO, OVERRIDE = YES - Management / Supervisor level
3 - SECURE = YES, OVERRIDE = YES - Owners C-level only.
