[Freeswitch-users] different moh in conference for each call?

[Anita Hall]

Hi

I am trying to play different moh sound for each conference call by passing
a variable to moh-sound from the dialplan to
autoload_configs/conference.conf.xml

In my dialplan/default.xml

    <extension name="conference_incoming">
        <condition field="destination_number" expression="^(.*)$">
                <action application="set" data="knowlus_hold_music=$1" />
                <action application="conference" data="3001 at default"/>
                <action application="hangup" />
        </condition>
    </extension>

In my autoload_configs/conference.conf.xml

<param name="moh-sound" value="local_stream://${knowlus_hold_music}"/>

However, it does not work. It is not able to expand the variable
${knowlus_hold_music}

In the log
2012-02-15 19:55:31.195264 [WARNING] mod_local_stream.c:393 Unknown source
${knowlus_hold_music}, trying 'default'

Is it even possible to pass a channel variable to a config file ? Or is
there another way to achieve what I am trying to do ?

Thanks.

regards,
Anita
