[Freeswitch-users] pass variable from dialplan to bridge

[dunchan]

Hi!

I have a simple question, how can i pass a varible from dialplan to the 
bridge?
I want to fill the 'from-user' field depends on sip user settings.

I've tryed the following in dialplan:
...
some conditions
...
<action application="set" data="from-user=${outbound_caller_id_number}"/>
<action application="bridge" data="sofia/gateway/upc/$1"/>

in a gateway xml i tryed:
<gateway name="upc">
         <param name="username" value="..."/>
         <param name="password" value="..."/>
         <param name="proxy" value="..."/>
         <param name="register" value="false"/>
         <param name="from-user" value="${from-user}"/>
     </gateway>

Above config ha no effect :(
any suggestions?

thx,
Viktor
