Environment variables
  • ASTERISK_AMI_PORTAsterisk Manager Interface port. Defaults to 5038.
  • ASTERISK_AMI_PASSWORDsecretAMI secret from manager.conf.
  • ASTERISK_AMI_TLSConnect to AMI over TLS. Set true if tlsenable=yes in manager.conf.
  • FREESWITCH_ESL_PORTFreeSWITCH inbound event socket port. Defaults to 8021.
  • FREESWITCH_ESL_PASSWORDsecretEvent socket password from event_socket.conf.xml. Defaults to ClueCon, which you should change.
  • PBX_MCP_ALLOW_WRITEUnlocks call control. When false the server is read-only and the originate and hangup tools are not registered at all. Placing a call on a live trunk costs real money, so leave this off unless you mean it.
  • PBX_MCP_TIMEOUT_MSPer command timeout in milliseconds. Defaults to 10000.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
