[Freeswitch-users] Alarm Cleared on channel - Suppressing

Hi all, I'm having sangoma A102 card and I'm using freetdm. For every 5 minutes, I get "Alarm Cleared on channel 1:1 to 1:31" and in FreeSwitch console. One of my friend told that in Asterisk, he will suppress this by setting resetinterval=never . Can any one please tell when this will occur and is there any way in FreeSwitch to suppress it?? please help!.
