[App_rpt-users] DTMF disable or rf side

HI All, is there a function in APP_Rpt that can be used to disable any DTMF from being decoded from the RF side but still work from the console? Today there was an individual trying to linkup _*all*_ the Allstar nodes to a particular node. It might be useful to use this feature to lock down a node to prevent his happening in the future if such an attack of the twitchy fingers happens again. Thanks, Jon VA3RQ
