[App_rpt-users] MDC1200 id access restriction.

I know that there is support for MDC1200, but is there the ability to restrict users of the node only to radios that transmit a specific MDC1200 ID (or set of ID's) at the beginning of each transmission? Or for the BAOFENG owners DTMF? TIA and 73. Geoff. -- Geoffrey S. Mendelson 4X1GM/N3OWJ Jerusalem Israel.
