Hi. I have a Openvox A1200P with 8 FXOs. PSTN calls via FXO card delays up to 30s to ring extensions but I need it to ring immediately. I have only one Inbound Route type "catch all" and only ring group associated to it. I edited /etc/asterisk/chan_dahdi.conf , changing immediate=yes and rebooted the system, but it seems not to work. Any help will be apreciated... Mauricio Faria.
