apope,
You are looking at the wrong timer.
Whether this is a UCD or ACD Hunt Group all of the timers that would effect the call are within the Hunt Groups Timers.
No Answer Advance - is the amount of time it will ring a station before moving on to the next one; up to the Recall timer.
Announcement - is the amount of time a call will be queued prior to going to the Announcement location; it only happens once and is usually for a RAD.
Overflow - is similar to the Announcement Timer, but it will repeat itself and will always add the additional time of the Announcement, if there is one, before it plays the first time; this is also usually for a RAD.
Recall - is the amount of time a call will be queued before it exits the Hunt Group without coming back.
Thanks,
TE
