[Freeswitch-users] BLF for database flag

[Peter P GMX]

Hello Jerry,


here is some minimal ruby code, we use to send presence data via ESL
interface

  # Send BLF presence event
  def self.send_presence(presence_id,status,hostname,direction=nil)
    uuid=UUID.new.generate
    if status==:up
      answer_state='confirmed'
    elsif status==:down
      answer_state='terminated'
    elsif status==:ringing
      answer_state='early'
    end
direction="outbound" if !direction

msg=<<EOF1
sendevent PRESENCE_IN
proto: sip
from: #{presence_id}
login: #{presence_id}
event_type: presence
alt_event_type: dialog
event_count: 1
unique-id: #{uuid}
Presence-Call-Direction: #{direction}
Answer-State: #{answer_state}
EOF1

  hostname=MY_GW_IP if !hostname
  f=FsSendEvent.new(hostname,port=8021)
  f.send_plain(msg)
end

For "FsSendEvent.new" and "f.send_plain" you should however do with
standard esl module, which can be compiled from Freeswitch sources. We
have created our own module here.

On
https://freeswitch.org/confluence/display/FREESWITCH/Event+Socket+Library
you will find an example under the bgapi section.

Presence_id can be formatted as you like, we sometimes do e.g.
**123*456789 and a phone then can subscribe to this.


Best regards

Peter
