Asterisk does this quite well:

[Synopsis]
Radio Repeater/Remote Base Control System

[Description]
   Rpt(nodename[|options]):  Radio Remote Link or Remote Base Link
Endpoint Process.

     Not specifying an option puts it in normal endpoint mode (where source
     IP and nodename are verified).

     Options are as follows:

         X - Normal endpoint mode WITHOUT security check. Only specify
             this if you have checked security already (like with an IAX2
             user/password or something).

         Rannounce-string[|timeout[|timeout-destination]] - Amateur Radio
             Reverse Autopatch. Caller is put on hold, and announcement (as
             specified by the 'announce-string') is played on radio
system.
             Users of radio system can access autopatch, dial specified
             code, and pick up call. Announce-string is list of names of
             recordings, or "PARKED" to substitute code for
un-parking,
             or "NODE" to substitute node number.

         P - Phone Control mode. This allows a regular phone user to have
             full control and audio access to the radio system. For the
             user to have DTMF control, the 'phone_functions' parameter
             must be specified for the node in 'rpt.conf'. An additional
             function (cop,6) must be listed so that PTT control is available.

         D - Dumb Phone Control mode. This allows a regular phone user to
             have full control and audio access to the radio system. In this
             mode, the PTT is activated for the entire length of the call.
             For the user to have DTMF control (not generally recomended in
             this mode), the 'dphone_functions' parameter must be
specified
             for the node in 'rpt.conf'. Otherwise no DTMF control will
be
             available to the phone user.
