i am confuse the param and variable in freeswitch, sometimes param is used for gateway, sometime variable is used for users
<param name="dial-string" value="{presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/>
<variables>
<variable name="record_stereo" value="true"/>
<variable name="default_gateway" value="$${default_provider}"/>
<variable name="default_areacode" value="$${default_areacode}"/>
<variable name="transfer_fallback_extension" value="operator"/>
<variable name="user_context" value="company-b.org"/>
</variables>
what is difference between param and variable
how to use param and variable
is there a list of variable and param
Thank you
