Hello, i'm a bit confused about how to port a special function i've on some asterisk system to Freeswitch. In my old asterisk scenario i've all the phones subscribe to extensions <sip:999@PBXIP> this exentions is configured not to monitor a device but a "DeviceState" variable, i.e.: 999,hint,DS/faxserver using dialplan i turn on the blinking status using DevState(DS/FaxServer,${RINGING}) and i turn it off when the call is hanged down. The same applies to other functions: queues, night service, etc. Under freeswitch the solution is http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_presence ? I tried but it didn't worked: presence in|999@PBXIP|dnd|'Do not disturb.' presence out|999@PBXIP|dnd|'Do not disturb.' The LED on the phones (Grandstream GXP 2010 or Snom 320) does not turn RED/ON. Any suggestion?
