[MT-AU Public] Asterisk Monitoring with The Dude

Hi all. I am wanting to monitor an asterisk box with our Dude implementation, I know I have done it before years ago but can't find any info on how. There are some other ways or doing it but ultimately I want to monitor the asterisk SIP port and make sure it is accepting connections and responding. Does anybody have any probe configuration information that works and that they are willing to share ? Any help would be appreciated. Thanks Paul
