 *
 * Repeater / Remote Functions:
 * "Simple" Mode:  * - autopatch access, # - autopatch hangup
 * Normal mode:
 * See the function list in rpt.conf (autopatchup, autopatchdn)
 * autopatchup can optionally take comma delimited setting=value pairs:
 *  
 *
 * context=string               :       Override default context with "string"
 * dialtime=ms                  :       Specify the max number of milliseconds between phone number digits (1000 milliseconds = 1 second)
 * farenddisconnect=1           :       Automatically disconnect when called party hangs up
 * noct=1                       :       Don't send repeater courtesy tone during autopatch calls
 * quiet=1                      :       Don't send dial tone, or connect messages. Do not send patch down message when called party hangs up
 *
 *
 * Example: 123=autopatchup,dialtime=20000,noct=1,farenddisconnect=1
 *
 *  To send an asterisk (*) while dialing or talking on phone,
 *  use the autopatch acess code.

"            user to have DTMF control, the 'phone_functions' parameter\n"

"            function (cop,6) must be listed so that PTT control is available.\n"
"\n"
"        D - Dumb Phone Control mode. This allows a regular phone user to\n"
