Still learning Symposium Script language and have an issue with how a caller queues. When the instruction is:
IF (CLID = east_area_code) THEN
IF NOT OUT OF SERVICE sk_east
THEN QUEUE TO SKILLSET sk_east
WAIT 5
ELSE
IF NOT OUT OF SERVICE sk_cent, sk_west
THEN QUEUE TO SKILLSET sk_cent, sk_west
WAIT 4
ELSE
EXECUTE Bkup_A

I know "IF NOT OUT OF SERVICE" means that agents are logged in and available for a call however, if the agent is on the call, does that mean the system 'sees' the skill set as "out of service"?

Also: Callers are queuing for 35 seconds or more before being presented to backup group A however if the agent in backup group A is logged in but on a call, the caller is held in queue and not passed to backup group B.

Question 1: if multiple skill sets are listed, does the service check each and wait 4 seconds for each or is it 4 seconds for the whole list?

The section above is one of three clid inquiries (east, central and west) that queue to different skill sets depending on the area code but all callers are passed to back up group A if unable to present to an agent in first skill set; then, if no agent is available in group A; the caller is supposed to pass to back up group B. Each area code backs up another (Central backs up East, West backs up Central, East backs up West)

Question 2: does the caller end up in a 'loop' because of the way the skill sets back one another up?
