[Asterisk-Users] tdm dialout delay

[Diyanat Ali]

Hello!


I am using asterisk 1.2.1 with a digium TDM card and trying to reduce the 
dialout delay to 1/2 secs at the most, i could bring it down from 6/7 
seconds to 3/4 seconds by tweaking the config and tone/zone/dtmf settings in 
the source, still this is not acceptable as the regular pstn phone takes 
less than 1 sec to ring on the called number
