Partner ACS AA rings to answer

[AKZ3BR]

I have a Partner ACS with the voicemail PC card. The incoming calls are answered by the auto attendant and transferred
to stations with the selector code programming. The AA picks up after the 3 ring I need it to answer calls right away.
Is there a setting for the number of rings before the AA answer. Any help would be helpful.

#506-(1=Day/2=Night)-(Line Number)-(Number of rings from 0 to 6)

Unless the ACS is R1 or 2, then it's #506-(1-Immediate (2 rings)/2-Delayed (4 rings))
