[Freeswitch-users] dynamic conference

[Carole O.]

Hello,

Thanks for your answers!
Concerning the creation of a new variable for the conference the problem is
that I do not create channels from the conference. I call separately a new
member on a new channel and add it on the conference only if he agrees to
enter it. So it was the same problem as for the uuid, I am not sure I can
access the good variable from anywhere in case many conferences are running.

So, I do the following if somebody is interested in:

<extension name="Local_Extension">
     .....................
      <condition field="destination_number"
expression="^${caller_id_number}$">
        <anti-action application="bind_meta_app" data="1 a o transfer::
transf_opp_leg_${db(select/conference/${caller_id_number})}_${destination_number}"/>
        <anti-action application="bind_meta_app" data="2 ab s
transfer::-both
transf_both_${uuid}_${caller_id_number}_${destination_number}"/>
       ..........
</extension>

<extension name="transf_both_legs">
     <condition field="destination_number"
expression="^transf_both_(.*)_(.*)_(.*)$">
         <action application="db" data="insert/conference/$2/conf_$1"/>
         <action application="db" data="insert/conference/$3/conf_$1"/>
         <action application="answer"/>
         <action application="conference" data="conf_$1 at conf_dynamic"/>
     </condition>
</extension>

<extension name="transf_opposite_leg">
     <condition field="destination_number"
expression="^transf_opp_leg_(.*)_(.*)$">
         <action application="db" data="insert/conference/$2/$1"/>
         <action application="answer"/>
         <action application="conference" data="$1 at conf_dynamic"/>
     </condition>
</extension>

This is not perfect and I am not sure it is "cleanly" programmed but it
works and it is flexible. All the members in the conference can invite new
members thanks to the conference name they all have in the database.

If you still have critics they are all welcome!
Thanks for your help,
Best regards,
Carole
