[Freeswitch-dev] mod_fifo

[Thierry Panthier]

Hello everyone,

If I use the below syntax, it works fine. But since I'm using
*$${variable}*(two $-signs) it only works for static values defined at
start-up.

  <fifos>
      <fifo name="emergency" importance="0">
        <member timeout="60" simo="1"
lag="0">{member_wait=nowait,origination_callee_id_name=*$${variable}*
}loopback/dequeue_emergency/default/XML</member>
      </fifo>
  </fifos>

If I use *${**variable**}* (one $-sign) I get the error:

   *Invalid data (${origination_callee_id_name} contains a variable)*
*
*
Since I couldn't find a way of using a variable from the dialplan, I
decided to solve the problem in my application.

Whenever I need to get the list of *callers* and *bridges* in the fifo*, *first
I get the list of UUIDs (with *fifo list <name>*) and then I use *uuid_getvar
<uuid> effective_caller_id_number*

I decided to share just in case someone has a similar requirement...

Regards,

Thierry Panthier
