Dialing slows down when dialed lead is NA

Hello all,
Some of our agents using the VICIDIAL System have told us, that their Wait time between the calls is often very high, and so we took a closer look and setted up a outbound-dialing test campaign, calling us itself with following settings:
RATIO=1
AutoDialLevel=1
DialTimeout=22 sec.
If the called Lead is available and picks up the phone, talks, hung-up, and then finishing the call, then VICIDIAL immediately calls the next Lead.
(Monitored by CLI).
The problem is, if the called Lead is not available and doesn't pick up the phone (NA-Autodial), then it takes nearly exactly 100 sec. (meashured 5 times consecutively) until VICIDIAL diales the next lead and so produces a very high wait time.
Our Vicidialsystem: Multiserver (Ast/Vici+DB/Web)
Slackware 12.1+scratch install+astguiclient 2.4.0.1RC2 updated to
astguiclient 2.4.0.1RC3
The rest of the system is all working very well.
So does anybody have an idea what kind of misconfiguration that could be?
Thanks in advance
