Hello , i have a quintum a400 tenor (analog series).. also ivr and radius server.. when call ended from both side (my tenor and destination number) quintum’s led turn off after one minute later.In pstntg prompt i’ve configured cassignaling to 1 and supervision 3.. Then same problem occured. And then i’ve changed casssignaling to 6 (loop fast and disconnect) and supervision 3 same problem occured too.. There is no wrong charge…Radius calculates the true calling time.. How can i solve this problem?
