i think gardo you have been anwsered good with the place of mflorell.
i have just say that centos it's not good with vicidial me too i have try it before with vicidialnow and also with scratch install we will find many probleme in compiling zaptel and timig voice .
but if we forget vicidial and we speak about the difference about debian family and redhat family they are no diffrence ;redhat want to kill the use of linux with the harden use of his and debian is more beautfull and more stable is his kernel and more answered in the net and you can seach google for this
it will answer you more good than me .
with my experience with vicidial i have found the configuration of asterisk+apache+vicidial+other module more confortable in this OS "ubuntu;debian;opensure,slackware,gentoo"
but centos=zero
i will give you a exemple:
try to make multiserver with centos version+adding a voicetimer device and try to work more than 25 seats for one weak non stop and say me the result after
i wait your answer
